Diesel Engine Problems of Volkswagen Jetta - part 2

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.

1) I purchased a vw tdi with a diagnosis of a bad turbo and an intermittent check engine light. I had the car seven months and put 12,984 miles on it with no problems. I took the car to the dealer and had the car diagnosed as to why the c. E. Light was on. When asked about repairing the turbo by the counter man I told him I intend to drive it until it breaks then have it repaired. I asked him if there would be a problem doing that he explained to me the car would be sluggish then not run. Vw diagnosed my car as having a "turbo waste gate blown" I deferred the repair intending to drive the car until the turbo went. 2) on the way home, six miles from the dealership, the car ran slightly rough. I observed light smoke coming from my car in the head lights of the cars behind me. I deducted my car was burning carbon since carbon build up was noted on the report. I slightly depressed the accelerator and the car raced forward. I immediately removed my foot from the gas pedal and nothing happened. The car raced forward so quickly and with such force I would compare it to a muscle car being floored. The car kept accelerating. I looked at the tachometer and it was going by 4,000 rpm. This diesel engine was screaming. Instinctively I depressed the clutch to regain control of the car. The engine revved then blew. I was 7 miles from the dealership. Service manger stated that a gasket in the turbo let go causing the engine to suck oil from the crankcase fueling the engine. He told me that nothing could stop the engine from revving not even turning off the key. He told me that all diesel engines were made this way. There is nothing vw could do for me. I called vw customer service, level 2 operator told me since I was told about the turbo being broken there is nothing they can do. 3) my car is sitting with a blown engine and a blown turbo.

Excessive buildup of carbon in the exhaust manifold leading to the failure of the car to start. This is a known issue among vw dealers with tdi diesels and there is nothing vw is doing about it. Cost $700 to repair this.

This complaint concerns the 2000 vw Jetta tdi diesel. Apparently, the egr system, in conjunction with the closed crankcase ventilation system, provides an opportunity for the crankcase oil vapors and soot from the egr to mix in the engine intake manifold. With time, the intake manifold becomes almost completely clogged with this oil/soot mixture, causing the engine to lose power and hamper such normal driving activities such as highway merging, passing, and emergency accident avoidance procedures due to loss of power. Volkswagen USA, the manufacturer, in many cases refuses to acknowledge the safety issue in regards to this gradual and severe loss of power, resulting in owner paid service charges which may exceed $1000 dollars (in some cases). Nowhere in any of the advertising or marketing literature of the vw tdi engines is a reference made to required periodic "intake cleanings" and it's inherent service costs. This vehicle is clearly not designed for safe and continued usage in the united states - people are going to get killed driving these things if vw doesn't acknowledge and repair this design defect, especially in high traffic areas.

Fitzgerald of annapolis failed to replace the stretch bolts when they changed the timing belt at 40k miles. At 130k miles, the bolts gave and the engine fell out of the car. I repaired this and continued to drive the car. At 140k the mounting bracket on the engine block snapped and the engine fell out again. The car now needs a new.

The consumers vehicle began to smoke when he applied the accelerator. This caused soot build up on the inside of the car. The soot was worse in the back of the station wagon. Soot affected the whole vehicle. The car was taken to the repair shop five times for this complaint. Consumer stated that it was six times, but the dealer did not log the first complaint in the computer. Consumer stated that the dealership was not acknowledging the first complaint. The dealership told the consumer that there was nothing they could do about the emission problem because this was a new type of diesel engine. The type of engine had a pump made to use euro diesel which will not be available in the united states until 2007. This information was not made available to the consumer before the purchase of the vehicle. The consumer didn't wish to pollute the environment. He also stated it was not safe for breathing. Soot could cause black lung disease. Manufacturer has been notified and claimed that there was nothing wrong with the vehicle, and it will not pollute the environment until 2007 when the diesel was converted. The consumer had a meeting with the Volkswagen representative. They offered to refund the cost of cleaning the car from the soot on the inside. The dealers phone number was not provided.

Repeat incidents leading to consumer's long term driveability concerns. Worrisome panel indicator lights -- flashing: engine warning and glow plug (diesel) lights within current lease period. After first two incidents, the third (then under warranty) was found to be due to a factory defect. And repaired?. . . Dec 7 '04, at about 55k -- blinking lights again. Dealer diagnostic indicated no engine problem (this was the same result of the two previous before the third resulted in a major warranty repair). This has been diagnosed as an accelerator sensor failure. (the part will not be available for three (3) days; we are advised to drive "carefully until the part can be replaced. ) this sensor failure is then one of several others in this particular vehicle: the fuel guage has been replaced once or twice; the seat heater sensor just, and out-of-warranty, burned a hole in the front seat (three weeks awaiting factory reps 'get-back. '). An air conditioning problem (leak) was also noted and repaired at about 50,000 miles.

2000 vw tdi manual transmission with 65,000 miles. Engine check light comes on, definite loss of power, worse when engine has been running for awhile. Car has no acceleration and can not hold speed going up relatively minor hills. Took it to the dealer who put it on the computer, said that the wastegate valve was stuck but was okay now. Problem reoccured. Definite safety problem on highway because there is no acceleration available to the driver.

Check engine light illuminated and there was no power to the vehicle. At highway speeds there was a severe vibration in the steering wheel. This resulted in a complete lost of power and a replacement of the injector system. The consumer was told that there was muddy diesel fuel but couldn't produce the fuel filter to back up the claim. There was another incident where there was a puff of smoke and a lost of power down to 25 mph on the road. The engine had a #3 valve go through the piston and run up and down the crankshaft. The engine was replaced along with another injector system and fuel pump was added. Several weeks later, a high pressure oil line broke from the weld and spewed oil everywhere. The axle assembly and the transmission slave cylinder were replaced as well.

I have a new 1999 vw Jetta tdi and I keep having problems with breaking oil pans. There is a problem with the groung clearance with the car. I am on mt 3rd oil pan and going on the 4th.

I am experiencing a loss of power on hills and when trying to accelerate an intermitant check engine light appears. I own a vw Jetta tdi 2000. The dealer diagnosed the problem 1st as a turbo control module, $252. 00. Some increase in power but not very much, check engine light off. 2nd trip to dealer after an 1-1/2 hour discussion about charging me another diagnostic fee and my consenting the problem was diagnosed as carbon in intake and egr valve replacement. I asked 4 questions :how does carbon get in an air intake?, how did the technician determine this was problem? why wasn't it identified the 1st time I took car in and what guarantee would I get? the dealer would not or could not answer these questions and the customer service rep at vw America has not answered them but has offered to pay 100% parts and labor for the repair after two days of calling and trying to get an answer from both of them. Don, is the customer service rep who offered to pay for repair upon my going to another dealer and paying for another diagnostic to verify the problem, as the first dealer has refused service to the vehicle because I insisted on answers to my questions before ok'ing repair. The number I called for vw America is 1-800- 822-8987. I have about 81,000 miles on the car and this problem creates a serious saftey hazard on the interstate or any highway where a slow moving vehicle may be a hazard.

2000 vw Jetta tdi- turbo does not appear to work for past 6-8 months. This causes the car to slow down significantly on any hills, including on entrance ramps, when trying to accelerate on merge with traffic. Dealership unable to diagnose, but has offered expensive repairs including replacing mass air flow sensor, some type of valve in the turbo, for example. Also noted is the vehicle can intermittently provide some diesel boost- seems only when the gas tank is full. And the fuel filler neck interior door has broken off sometime in the past year. Is this related? is this safe?.

Vw Jetta tdi- the turbo hasn't been working. Apparently, this vehicle is equipped with a ccv (crankcase vent) system and an egr (exhaust gas recirculation) system. Oily fumes from the ccv system combine with carbon particles from the egr system to form a black sticky tar in the intake system. This eventually starts restricting the amount of airflow into the engine, resulting in gradual power loss as the vehicle ages and the intake clogging becomes worse. This is apparently preventable by adjusting the intake air volume of 370 mg/stroke using a computer to reprogram the egr. Replacing the manifold & egr is an expensive proposition that is not covered under the powertrain warranty.

The tubo power in my vw Jetta 2002 tdi model failed multiple times over a two year period. Vw dealer in manchester, nh was not compident enough to go beyond what the diagnosis machine was telling them to fix. Vw manufacturing was more than reluctant to cover costs to fix the problem even though the problems started before the warranty was up.

Shortly after buying car I noticed it was using excessive oil, in the worst instance it used approx. A quart and a half in 1500 miles. I notified the dealer and manufacture and both said it was normal consumption. I have never had or heard of new vehicles using such an amount in so little miles. Also had a problem at 14000 miles with a throttle surge on the morning startups. Tach would read various rpm's while this was occuring. Then when I would start to accelerate slowly the engine would still surge causing the vehicle to "buck" violently! this condition is very unsafe since it is totally unpredictable. This problem is still occuring at 41000 miles and has taken over 6 days in the shop with no diagnosis. Dealer thought the timing belt was the problem since it had streched so far out the timing couldnt be reset. I will pay to have the timing belt replaced but that didnt fix the problem. In 1998 volks wagen reccomended that on the diesel engine the timing belt should be replaced at 60000 miles but the reccomendation has changed for the year 2000 to 40000. This change has to be due to early malfunction problems with the belt but Volkswagen denies any problems and will not cover the belt under warranties either. If the timing belt breaks while on the interstate or highway , it could cause an accident since there would be no power steering and or brakes not to mention if it causes the transmission to lock up. This engine has big problems that need to be addressed. . . Thank you.
