My Jetta diesel engine was hydro-locked due to water being pulled into the engine from the intercooler. Volkswagen has a TSB (technical service bulletin) published for this exact problem (frozen intercooler) - yet is only implementing or offering this TSB to customers on an as needed basis. In many cases - this is way too late. This is a known problem at Volkswagen -- and by not offering this TSB to all vw customers -- catastrophic engine damage can occur - if the right weather conditions are met. For my vehicle, when starting up my car - at the end of the day, to leave and return home --> when starting the car - it acted as if the battery was dead. At this point, water was ingested into the 3rd cylinder, the piston rod of the 3rd cylinder was bent, and engine damage was done. Vw should not be offering this TSB to all tdi (turbo diesel engine) owners who could be affected by the TSB. Catastrophic engine damage by neglecting to perform a known TSB is creating a very dangerous situation on the roads.

I was on my way home after work approximately 6-7 pm doing 45 mph. I looked down to my instrument cluster to check my speed to make sure I wasn't speeding. Then I saw the glow plug light blinking multiple times then about less than 5-10 seconds later my engine cut out. I cost off into a harper college parking lot came to a stop. I tried to start the car 2-3 times, each time the engine was crackin over but wouldn't start it up. I called the tow truck company and had the vehicle towed to vw dealer in schaumburg, IL ( fox valley vw) dealer said the high pressure fuel pump failed. Vwoa cover this under power train warranty 5/60k warranty. The dealer replace hpfp,lift pump, pump in gas tank,fuel lines to engine,coils etc. . . Repairs came to roughly $5300. 00. Vwoa only give 12/12k miles warranty on the hpfp. This is a known problem on some vw with cjaa 2. 0l turbo diesel engines and vwoa has not found the defect in the hpfp. Vwoa should extend the hpfp to 100k miles due to deft in the hpfp since they haven't found the problem and corrected it.

Car is a Jetta tdi (diesel engine). Engine warning light appeared while driving, approximately 50 yards later while slowing down the engine failed and would not restart. Car was stopped at intersection on a busy 5 lane road at 5:30 pm with cars coming from behind and around at speeds of 45+ mph. Sheriff came to divert traffic to prevent a wreck and allow tow truck to tow car safely. Dealer states that high pressure fuel pump failed, ruining fuel system, quotes potential repair cost of $8,500. Filled fuel tank 5 miles prior to incident with 11 gallons of diesel fuel (reputable fuel dealer, almost always use this dealer). There was no warning prior to the incident -- no rough engine or stalling or trouble of any kind. Car is driven by only one driver and is well maintained, has never been fueled with anything but diesel from reputable dealers. Car is usually driven on the freeway (dealer recommended it specifically for a long freeway commute). Lucky that it didn't stall at high speed on freeway.

I was on the exit ramp of the interstate and the go to workshop warning came on along with the glow plug warning light. Vehicle lost power, I was able to get to a side street and turned off vehicle, it restarted and seemed fine drove about 2 miles and stopped for a light, car stalled and warning lights came back on. Car did not restart had push to side of road and tow home. Towed to dealer first of week. Found to be high pressure fuel pump failure of the diesel engine. This is the second one to go bad first one at 135380 miles and now at 228605 miles only 93225 miles on repair job. Vw repaired the first one, replaced entire fuel system at no charge, do to faulty hpfp. Even though this pump has less miles they will not help with repair cost. Both times car died at a major intersection and had to be pushed to side of road.

Tdi diesel engine. Entered highway, car stuttered, engine died, displayed workshop code problem, glowplug light flashing. Restarted one time, traveled to parking area, engine died and would not restart. Code was p0087, fuel pump pressure failure. No previous problems or hints of this issue. Sudden engine failure. Very dangerous, was driving uphill, the one restart allowed me to leave road. Dealer noted no fuel contamination. System was properly primed on fuel filter changes. Used a ross-tech cable and software. Repair is expected to be about $7000. 00. Previous diesel 2001 model was still running with 332,000 miles when this one was purchased. Tdiclub. Com website has noted many of these failures, search hpfp, high pressure fuel pump. Vw is not furnishing pumps designed with the us diesel fuel quality in mind. Vw needs to correct this problem, there have been a lot of these failures.

Failure Date: 03/17/2012

Ice in the air intake caused the engine to vapor lock which caused a bent piston rod. Dealer is going to remove the factory air intake after installing a new engine under warranty and claims this is an engineered fix. Dealer also said that Volkswagen is working on some heater add on in the possible future. I suspect that the current fix is not a fix as the trouble was not when driving it was after the car set for a few days and ice formed in the intake. Nhtsa should investigate to confirm the engineering issue is addressed correctly to protect consumers.

As my wife was driving towards a stop sign at a relatively slow speed, the vehicle check engine light came on and then the car died. As she started to roll backwards, she stopped the car and waited for the other traffic to clear. She was able to restart the car and drive it home as she was less than a mile away. After I returned home, I started the car and noticed the check engine light. At that point the car seemed fine. I went to autozone to see if they could download the error codes that might provide some insight into what component was causing the problem. They could not do that according to CA law. I purchased a obdii code reader and discovered code p0191 and p0087, both relating to the fuel system. P0191 indicated the fuel rail pressure sensor a circuit range / performance. The p0087 indicated the fuel rail / system pressure too low. While researching these codes on the internet I discovered a huge amount of information relating to this issue. I am thankful my wife was not in a huge amount of traffic as she could have been in an accident as a result of the car shutting down without warning. This has been going on with the tdi diesel engine since 2009. Why has there been no recall to fix what I believe is a defective or inferior fuel pump. In the many work orders I have read vw in many cases blamed bad fuel (gas in the diesel tank) as the problem. I have written documentation for every gallon of fuel that has been put in this car since it was new. The car has had all scheduled maintenance completed since the car was new. If this is a known problem why wasn't a recall issued like they did with the dsg transmission. Is this denial on vw's part so they don't get a bunch of bad press?.

This concerns a 2009 vw Jetta tdi (clean diesel version). Car dashboard put out warning message "engine malfunction" then car began to sputter and lose power. Electronic dashboard showed there was plenty of diesel gas in the tank (enough to continue driving 250 miles). (the car had been filled up with diesel gasoline on the day before, Friday, and driven on a short trip that Saturday during the day hours; driver had filled up at that station regularly across the last 2 years since the car was purchased. ) electronic dashboard also showed all other systems functioning regarding battery, temperature sensor, etc. Driver was on busy city avenue in fullerton, California traveling at about 40 mph when sputtering began. Car power slowly decreased to about 20 mph, but fortunately driver was able to make it through several green lights to a commercial area. Fortunately Saturday night traffic was not heavy, so a lane change to the right was possible without affecting other drivers who wished to go at a faster speed. Car slowed down to about 5 mph as driver maneuvered car for the last 500 feet into a gasoline station parking lot. Car engine came to a complete stop. This was less than 5 minutes after the first "engine malfunction" warning on the electronic dashboard. Attempts to restart the engine were unsuccessful; a clicking sound in the ignition was heard. Car engine subsequently would not turn over and had to be towed Saturday night.

30 sept 2011. While sitting at an intersection we noticed a rattling sound coming from our 2009 Jetta tdi. Could also feel a slight vibration through the shift lever and steering wheel. Initial thought was an a/c clutch issue due to a squealing sound that started. Proceeded through the intersection and accelerated to approximately 30 mph when the "engine fault workshop" light came on and the sound became very loud. We immediately pulled into a parking lot to investigate. Loud metallic noises appeared to be internal to the engine not external. Shut the car off and it would not restart. Car was towed to mossy vw (classic Volkswagen) in escondido, CA at closing time and will be troubleshoot in the morning. 50,000 miles on the car. Great dealer so far, service stayed late to assist and ensured we had transportation home. A quick online search revealed hpfp failures for 2009 vw tdi cars are becoming more common and unfortunately the manufacturer is not acknowledging and some dealers are blaming on fuel contamination with unleaded gas. Owners are reporting $10,000 repair bills. We have our diesel fuel receipt from yesterday, 29 Sep 2011, confirming correct fuel was used.

The contact owns a 2005 Volkswagen Jetta. While driving approximately 65 mph, the vehicle stalled without warning. The failure would occur intermittently. The engine would also misfire and the vehicle would jerk and decelerate. The vehicle was taken to the dealer for diagnostics where the technician advised the contact that the b valve, the glow plug and the glow plug harness would have to be replaced. The vehicle was repaired but the failure continued after the repair. The vehicle was taken to a second dealer for diagnostics where the technicians stated that the direct shift gearbox unit would have to be replaced. The contact referenced a recall for the 2009-2010 models under NHTSA campaign id number: 09v333000 (power train:automatic transmission) but was advised by the manufacturer that the recall did not include the 2005 model vehicles. The vehicle was not repaired. The approximate failure mileage was 118,000. Updated 04/02/lj.

Camshaft failure causing all associated/connecting parts to also fail. Never deviated from specified manufactures required oil (505. 01). This appears to be a design problem, that is common on all these diesel engines (brm), of which the manufacture will not correct and the owner is required to correct at their own expense at a cost of $2000 plus.

I purchased a 6-speed manual transmission Jetta-tdi at the end of December of 2009. I have been driving manual transmission cars since 1975, and I was upset that my car was stalling either just starting out in first or in the lower rpm range of the lower gears when turning and moving through intersections or trying to go uphill when the rpms were in the lower range. Keeping the rpms up a bit seems to have helped, as I am not having it stall as much as before. I also noticed what seemed like a slight hesitation or jerking when cruising . It would be just for a split second and then be gone my accident occurred when I was parallel parking on a hill. I went to back up a bit to straighten out my car and it stalled, rolling forward into the car parked in front of me. Fortunately, no one was injured. Damage was minor, but was submitted to my insurance company. At this point I was just blaming myself for not being able to adjust to the difference of clutching with a diesel engine because I couldn't figure out how to explain it. Then a heard 2 radio reports about the complaints being filed. I called vw of America who listened to my story. They told me that in order to be compensated for my accident, that I would have needed to have had the car towed immediately to a dealership and had it diagnosed. She suggested that I take it to be diagnosed. I took it to the dealer who kept it for two days and could not find anything wrong. A week later, I was coming to a stop for a red light and the rpms began to fluctuate like it was going to stall and then it would come back to normal rpms. When I started to drive it was a little rough, then smoothed out. I called vw of America who recommended that I take it back to the dealer. I am waiting for them to return my call. I have also 3 intermittent problems with my am radio cutting out--are the problems connected?.

I was driving on a secondary highway going only 30 mph when a warning light came on. At the same time the engine started running very rough. I immediately pulled the car to the side of the road. At the side of the road with the engine off, I pulled out the Jetta handbook to research the meaning of the warning light. The light blinking was the engine malfunction light. After that I called the vw 800 road side program, a tow truck came and towed the Jetta to the dealer. Now this morning I go to the dealership and they inform me the cost of getting this new car fixed will be $6,800. 00. With that information I have to ask why and the dealership proceeds to say I have "bad fuel". The comment by the dealership triggered all types of responses. The first response was proof I put the right type of fuel in the tank which I did. Next I had to go and get a sample of fuel from the filling station. After that I delivered a sample of the fuel in question to the dealership for testing. As it turns out the fuel was okay. While I am running around doing all of this my wife finds out via the internet of issues the Jetta is having with the fuel pump. Keep in mind, at no point has the dealership given me information regarding a possible fuel pump issue, which would be a warranty issue, aka no cost to me! it is now 5:20 pm and I have not heard from the dealership. Now I have another issue, is the dealership trying to defraud me? and if so the dealership will have big problems.

Vw has changed the diesel engines (tdi) starting with aproximate year 2004 until 2007, when they stopped selling tdi to meet emission requirements. To save money and licesing fees to bosch they have changed from common rail system made by bosch (feeds the diesel fuel to engine with very high pressure) to vw system called tdi pumpe duse (or pump-nozzle injection). To accomodate the injectors inside the engine, they have changed the specs and dimensions of many parts, including the camshaft. The camshaft inside this engine has the added role to drive the pd lifters, appart from valve lifting and closing. I own this type of car vw Jetta 2006 tdi, and the camshaft wore off at 80,000 miles, and yes it was out of warranty and it costs $3000. Appart from the costs, which accrues to aprox $3000 per 50,000 to 80,000 miles rendering this car a liability cost to the owners (a long term owner will have the price of car doubled by added bills to change the camshafts many times. This impacts drasticaly financialy many famillies depending on this car), without the possibility to fix it permanently and for once . I have changed the camshaft and now at 115000 miles it starts to shows signs of wear, like last time. Not changing gears in time, car is shaking. The effect gets worse, until when the camshaft lobes wears off more, and results in valves not opening and closing in right sequence and time, and engine will stall, like mine did on my street. As well I was on highway and car will not operate and respond to acceleration pedal input, maximum pedal input was giving only 40mph, exposing me to a stampede of cars from behind in a dangerous situation unable to control the car. I have explained the situation to vw and they deny any: wrongdoing, design flaw, fault or liability. According to tdiclub. Com there is up to 20% failure of the engines via camshaft wear of lobes. I trust you will investigate and request vw to address:safety+financial impact to tdi pd owners.

1-hallmark coolsprings Volkswagen in nashville tennessee used improper oil in my 2009 Jetta tdi. I did not discover this until after the improper oil had been in the vehicle for over 7000 miles. This is documented on their service report. The vw technical supplement entitled: jetta, Jetta sportwagen equipped with tdi engine, model year 2009 which was included in the owners manual of this vehicle states:if you use engine oil that does not expressly conform to Volkswagen oil standard 507. 00, very serious and very expensive damage to your vehicles engine will occur. ¿ it goes on to state: failure to use engine oil for your diesel engine that conforms to Volkswagen oil standard 507. 00 can cause engine failure on the highway that can cause a crash and serious personal injury. ¿ 2-now I have no alternative but to drive the car, paranoid that what the owner's manual says will happen to happen and hope the engine does not lock up and cause me to wreck and hurt myself and/or someone else. 3)- Volkswagen of America will not help do anything about this and neither will hallmark Volkswagen. They basically say to disregard the owners manual - I believe they are in violation of the magnuson moss act if the oil specified in the owners manual doesn't really have to be used to avoid engine damage, resulting in a vehicle accident.

The contact owns a 2009 Volkswagen Jetta. While the contact was driving approximately 70 mph, the engine warning indicator illuminated followed by the engine stalling. The vehicle failed to restart and was towed to an authorized dealer for diagnosis. The vehicle was repaired; however, a similar failure occurred a second time and the vehicle was taken to a different dealer and repaired. The manufacturer was not made aware of the problem. The approximate failure mileage was 5,000. Updated 12/13/11.

Car stalled 5 times over a two day period duel to a failure of the fuel pump. Dash board warning said "engine fault workshop" and glow plug warning light came on. Owner manual said to bring into shop soon. Dealership found metal shavings throughout the fuel system that was caused by a failed high pressure fuel pump. The warning lights first came on when their was a near empty condition in the fuel tank. I have heard that this has happened to others when fuel is low. Cost for repair would have been around $6000, but vw warranty covered this. If this stall had happened on the interstate it would have been very dangerous. As it was I had a police car push me out of an intersection during rush hour to a safe spot.

My driver's side window suddenly stopped working. I took it to a repair shop and the mechanic said that piece that holds the window in place was stretched and about to break. When I spoke with a friend who used to own a Jetta of the same year, make, and model as mine, he said that the same thing had happened to his vehicle. He said that there had been a recall on this part. When I checked the NHTSA's web site, however, I could not find this recall. The consumer had problems with the engine and the sterring column was defective. The engine light illuminated right after the vehicle was purchased. Updated 06/01/09.

The engine in our 2006 tdi dsg began to exhibit rough idling. At a certain point it became evident something was wrong. The vehicle has always been serviced by a vw dealership at the specified intervals (I call them the $400 oil changes). I could hear what sounded like an intake valve popping and could feel a pulsation in the turbo intake hose. I checked on some of the forums and was shocked to learn of the early camshaft failure problem common to the pd engines. It seems that vw narrowed up the intake and exhaust cam lobes by about 30% to make room for the injector lobe, and tried to compensate for this inadequate design by mandating "special" oil (which I can only hope our dealer used each time the oil was changed). It turns out though, that a critical can wear additive in this oil, zddp, in sufficient quantities can cause early failure of the catalytic converter (an item which has a longer warranty period than the engine). It seems that the zddp only exists in sufficient quantity in vw "special" oil to get through the engine warranty period, while at the same time protecting the converter from warranty failure. I bought an after market cam kit and installed it myself, saving nearly $3000 in the process. Since then we've put another 60k miles, using mobil td truck 5w40 oil. . . So far so good. I think this whole situation is disgraceful at best and vw should be responsible for all pd camshaft failures to a period significantly longer than the 80,000 km warranty. The primary reason we paid 32k for a compact sedan was the reputed longevity of the diesel engine. This failure, along with the dual mass flywheel fiasco has made our purchase of this silver colored lemon anything but a good investment. Until vw faces up to their moral responsibilities in this matter I would caution anyone considering this make of vehicle.

The contact owns a 2000 Volkswagen Jetta. The contact took the vehicle to the dealer for maintenance work. While it was being test driven at 30 mph, the engine failed. The mechanic stated that a seal failed, which allowed the engine to fail. The contact was unaware of which seal was affected. The dealer repaired the vehicle and installed a new engine. The mechanic also stated that they were aware of the failure due to numerous others that have experienced the same failure. The failure mileage was 86,900 and current mileage was 89,000. Updated 03/05/09 the engine had 2 broken rods the #3 and #4 and there were large holes in the block. The failure was due to hydraulic lock or a volume of oil getting in the cylinder and stopping the piston. Updated 03/12/09.

I have a 2006 Volkswagen Jetta tdi. Initially I was slowing down on the interstate, as soon as I was getting ready to stop due to construction, when the shifter hit first, the car bucked, died and I lost power steering and brakes. I also noticed that none of the gears in the transmission would sync and allow me into them. I pulled off to the side of the road, when I realesed my foot from the clutch, the pedal did not come back up. I shut down the car, crawled out the passenger side, I looked under the car for leaks and anything that may indicate a major failure. When I pulled the clutch back up manually, the pedal would not go back down but half way. I pushed hard enough to get the clutch interlock switch to disengage, and tried to start the car. When the starter engaged, the engine dragged with something else. I abandoned the car to get to a phone. When I called the dealer, they gave me a phone number to roadside assistance, they wanted to charge me to tow the car to the nearest vw certfied repair shop. Eventually I convinced them to tow the car, and when I met him at the car, I noticed a leak of either hydraulic, gear, or diesel fluid. When I got on the internet I found that this is a very common problem due to a poor desing in the flywheel. Vw tends to refuse to replace the clutch claiming that it was premature wear due to poor driving habits. The flywheel tends to crack or even shatter causing not only clutch issues but also transmission and engine issues. This issue can lead to wrecks fires and also even stranded people that may have no way of getting help. Volkswagen has recalled the flywheel in europe but refuses to do so in America. . Read more...

While driving at 65 mph on a 2 lane undivided hi-way; engine cut out, without warning of any kind (1. 9 litre diesel-2000 Jetta) this obviously caused an unsafe situation. Vehicle would turn over but not start. Dealer repaired by replacing power relay for engine control module (relay 109). Have researched this relay on various sites, and found dozens of failed relays, some in similar circumstances. Apparently, the original black relay fails, new relay is a change up (grey in colour).

I own a 2005. 5 Volkswagen Jetta. Just prior to the 40k service the car developed a dangerous power loss problem which rendered the car powerless and the only way to clear the problem was to pull over, shut the car off and restart. We took the car into the shop for our 40k service and no problem was found. In July we took the car on a road trip to santa fe nm and the problem became chronic. We took the car to premier motorcars in santa fe 505-428-5521 on July 5th, and as of today, August 24th the car is still not repaired. I have also joined a forum where I have met others with the came car, having the same problem and their cars are not being repaired. I have their names, ro numbers and vw claim numbers upon request. There appears to be a serious problem that so far appears to affect the 05. 5 Jetta tdi models. The problem causes the car to enter a "limp mode" where basically the horsepower is reduced dramatically and can happen unsuspectingly causing the driver to not be aware of an unsafe condition entering traffic. To make an example the first time it did this to me I was at a stop sign at a busy highway. I had sufficient clearance to cross but unknown to me my car had lost power but I didn't realize this until entering the intersection causing me to barely miss an oncoming car. Vw has been very uncooperative with all of us as far as letting us share our information with them. I have compiled the service info for all of these people and shared it with each and when we speak to vw they refuse the information. It appears that vw has no idea what is causing this problem leaving many of us without our cars for months.

This has not resulted in a crash on my behalf. While driving on the highway with cruise control set at 75 mph the car will occasionally (averages once per every 1500 miles) hesitate then resume normal operations. The duration of this event is approximately 1 - 2 seconds. The effect of this being that the car suddenly starts to decelerate then suddenly resume normal behaviour. There are no inidicator lights or events logged in the onboard computer. The vehicle has been in the shop numerous times where they are unable to reproduce the issue. I have offered to drive around with a computer running vagcom (a vw diagnostics app) if they would provide it in order to catch the issue, yet vw and the local dealership refuse to do so. This incident has occured at least 5 times in the previous 4 months, once while my wife was driving. That particular incident nearly resulted in her running into the highway divider. The date noted below is the first incident.

On 1/25/2007 our vehicle was taken in to dealer service department for repair of an engine vibration. Initial diagnosis was the timing belt and it was adjusted approximately 4 degrees and promised to be ready on 1/27/07. Belt adjustment did not fix the problem and car was not picked up. Additional diagnosis was performed, including compression test of engine, and technician contacted Volkswagen for assistance. After weeks of diagnosis and testing we were told that the in tank fuel pump that was replaced at a different vw dealership on 9/11/06 had failed. Researching NHTSA I also found out that it was a recalled pump. Because the mileage was almost 3k over the warranty of the part and vw already satisfied the recall vw would not cover a replacement. The new fuel pump also did not fix the vibration problem. Dealers diagnosis with Volkswagen's assistance continued until 2/8/07 when we were told that a valve lifter in the cam assembly had failed causing the vibration. Dealership recommended a complete "cylinder head replacement" at a cost of about $4,500. My husband asked to speak with the mechanic and determined that the damage was only to one valve lifter. My husband and I decided to fix what was broken and only fixed the damaged lifter which was estimated at about $500. The dealer agreed to perform this repair, but would not warranty the work because they were concerned that cylinder head might be faulty. Our vehicle was finally repaired and able to be picked up on 2/19/07. Cost of repairs was negotiated within our satisfaction, however, the service was not timely and feel that the parts in the vehicle are below standard. Now we have an additional problem we did not have before taking it in for repair. Two days after we received the vehicle from the dealership we figured out the fuel gauge is no longer working properly and has a false reading of approximately 1/4 tank when the tank is empty.

Engine light came on and the 2001 tdi was taken into the dealership. The dealership identified the problem as a faulty glow plug. Upon trying to remove the glow plug, the dealership broke the part. Now, the only way to remove the glow plug is to tear apart the engine, at a cost of over $1,000. Dealership will not allow me to take the car back either. Called vw customer service and they are fine with the dealership holding my car hostage. Vw must hate the customer.

While driving my new 2006 Jetta tdi motor vehicle with a total mileage on the odometer reading of approximately 385 miles, on June 12, 2006, on I-84 in waterbury, CT. The motor vehicle stalled while traveling in the left hand lane of the highway. At the time of the stall, the vehicle transmission was operating in the drive mode, in 5th gear with rpms at approximately 1300 rpm. During the stall the vehicle exhibited intermittent power, while the instrument panel exhibiting a flashing numeral 3, on the gear indicator. I maneuvered the vehicle to the breakdown lane with much difficulty as the engine stalled out completely. This maneuver caused a major interruption to the flow of traffic on the highway and a serious safety risk to me and other motorists on the highway. After pulling over the breakdown lane, I was able to restart the vehicle and proceed to my destination, during which time the vehicle operated normally. On June 15, 2006, driving with approx. 484 miles, while on rt. 8 southbound in waterbury, CT. The subject motor vehicle stalled once again while driving in the left hand lane. I once again was forced to make another emergency crossing of a major connecticut highway in a stalled vehicle.
