The coolant temperature sensor warning light comes on during cool and cold weather and stays on till the engine is warmed up. At which time, if the engine is turned off and then restarted, the warning light will remain out. There are no codes listed in the ecu. This issue has occurred continuously since the car was purchased in June 2005.

My Jetta has been in the shop more times than not. The latest incident began with my car overheating. After 1300 dollars later, the repair shop told me that this year of the Jetta has a plastic part that sits on water pump. That part has had to be replaced by many Jetta owner's after the replacing of the water pump.

I purchased a 2000 vplkswagen Jetta in the year 2002, pre-owned. I have had nothing but problems with it since I bought it, and now am trading it in, and taking a $3000 loss. Here is a list of the problems I have had in the last 2 years listed from first problems to most recent: 1. Window tray broke, window fell into the door. $300 2. Trunk latch broke, had to get replaced $50 3. Sunroof broke, would not move and needed the entire thing replaced including the motor. $1800 4. Water pump leaked out all coolant, needed to be replaced $ 600 5. Strut coil snaped in half while driving, needed to replace both sides $500 6. Lastly, (this is the point when I decided to file a complaint and trade the car in for another brand) water leaking from the electrical panel on top of inside roof. Sunroof then malfunctioned, opening when the car was started and the knob was not touched. Had to pay to disconnect power sunroof. Whatever you do, please, do not buy a vw Jetta. That is unless you want to have it continually in the shop and having to spend a lot of money on repairs.

The thermostat housing needed to be replaced due to coolant leakage. This part had to be replaced to prevent coolant loss. I had to purchase the part and pay to have it replaced.

Problems with air conditioner on 2003 Volkswagen Jetta. The air intake duct leaked which caused white smoke to emit from the vehicle when parked after a 75 mile trip. The part had to be ordered. The a/c condenser leaked which caused the a/c not to cool the vehicle properly. The dealer surmised that the damage to the condenser was from an outside source therefore refused to replace it under warranty.

Consumer states vehicle burns oil prematurely. Dealer notified.

I purchased my Jetta in March 2002, and experienced no major problems within the first 30,000 miles. On July 19, 2003, I brought the car to vw after hearing a rattling noise when making turns and idling at a traffic light (mileage: 33,996). The mechanics were unable to identify a problem, however at the same time, the ignition coils were replaced due to a vw recall, the first of several. I continued to contend with the rattling for several more months, and finally brought the car back to vw on November 14, 2003 (mileage: 39,038). At this point, the pressure hose was replaced under warranty. My car functioned without incident until July 2004, when I began to notice that the air conditioning worked sporadically. I did not realize the connection to the engine cooling system until August 25, 2004, when my car began to overheat. The vehicle was towed to the nearest vw service shop in, where I was charged $4 for a cooling fan fuse and $90 in labor (not to mention the brake light switch was replaced due to another product recall). I was charged $101. 76, and the problem was still not solved! on August 27, 2004, I spent $659. 04 in parts and labor to have both the ac and radiator cooling fans replaced (mileage: 52,650). I drove my car with no problems until November 16, 2004, when the check engine light came on. I spent another $93. 28 for a new coolant sensor, coolant refill, and labor. The check engine light came back on in April 2005, and resulted in another trip to the mechanic, costing me another $45. 53. On August 5, 2005 (mileage: 68k), my car overheated yet again. The current situation I am faced with is $450 in parts and labor to replace the water pump and $150 to replace a vacuum hose. I am hesitant to drive my car, for fear that it will overheat again, or worse, while I am driving it.

A strong smell of anti freeze can be smelled inside he vehicle while driving. The dealer was notified.

The contact owns a 2003 Volkswagen Jetta. The contact stated that over the years her vehicle sporadically overheats. She took the vehicle to the dealer on numerous occasions and had the oxygen sensors replaced twice, the thermostat, the battery, the water pump, and the auxiliary water pump. Recently, while driving approximately 60 mph, the vehicle overheated and was towed to the dealer. The dealer stated that the radiator fan, secondary air pump, and the power steering pump needed to be replaced at the cost of over $2,000. The technician added that if the repair was unsuccessful in remedying the failures, they may have to replace the catalytic converter. The manufacturer would not assist. The failure mileage was 63,126 and current mileage was 76,000.

Vehicle suddenly loss engine power and can not be driven. Dealer notified. Please provide additional information. Ts.

The rear passenger tire came off on the highway while going 35mph. The wheel bearing axle failed causing the vehicle to drop to the ground with the brake drum still attached to it . The dealer was notified and the problem was due to neglecting the wheel bearing for regular service. Nlm the brake drum outer and inner wheel bearings were replaced. The cooling system was loosing coolant at times.

The coolant sensor was repaired but it failed again.

Every summer especially during 90 degree temperature, the temperature guage moves to highest setting and often times vehicle completely shut off to cool down. Vehicle will starts again after cooling down. This happens only during hot summers.

Map failure. But also "coolant migration problem. " wherein, due to faulty coolant reservoir sensor seal, coolant migrated out of coolant reservoir and into wiring harness causing speedo and cruise control failures. Was repaired at no cost, as was maf. However numerous tdi and gasser owners are constantly reporting maf failures.

This part was replaced under warranty. However, my warranty is almost up, how many more will I have to replace?.

Engine check light came on. Car was 14 months old, but out of warranty by mileage. The dealer replaced the coolant sensor for $175. 00!! now two months later the "check engine" light is on again. There appears to be water/coolant in the oil! now the car is about 16 months old. Volkswagen of America refused to pay for the prior repair, and did not pay for the failed interior lights, either.

The engine coolant system on the car has never been right. One month after purchase we brought the car into the dealer because the transmission shifted poorly when the car became hot. It would up shift and downshift for no reason. They told us there was nothing wrong. That this is how they shift. The transmission still shifts in this manner. Then in October of 2000 the coolant warning light came on. We were told by the dealer that the coolant temperature sensor needed to be reset. They reset the sensor and on 10/27/2000, just two weeks later, the coolant warning light came on again. This time they replaced the coolant temperature sensor. Then on 7/16/2001 the coolant warning light came on again and we needed to have the secondary water pump replaced. Now on 8/9/01 the vehicle is at the dealer again because the coolant warning light came on. I am writing a letter to the manufacturer. Any further advice or assistance you can give would be greatly appreciated.

While driving 60mph heard a clicking noise. Then ater pump seized & caused vehicle to stall out. Pulled over. Had vehicle towed to dealer. Informed by mechanic it was the water pump which sheared off the timing belt & damaged the valve head. Problem was repaired except for the clicking noise that was still there.

Vehicle has excessive engine oil consumption and loss of cooling at the same rate, which could cause engine failure/fire and air pollution. Owner has contacted dealership two times about the problem. Also, gear selection and engagement of the transmission are slow to respond to input. Dealer says that these problems are normal.

Electronic thermostatically controlled fan vibrations caused the electrical connection to become unreliable in vehicle. Eventually this connection was completely severed causing the fan to become inoperable leading to engine overheating. Before the connection failed completely, a spark would be created when the radiator temperature switch or the air conditioning switch would send power to the fan. I believe this is a safety problem that could have led to an engine fire.

The engine light illuminated, the dealer stated the ignition coil was defective. The vehicle over heated, and the problem was diagnosed as a ruptured coolant pump.
