Engine lights come on. Car at times start shaking - not consistently though. Took it to shop: found out ignition coils misfires. This has occurred 4 times in a 2 year time span. The most recent 2 being a month apart. The most recent incident burned almost all of the spark plugs. Did research and this website describes my situation perfectly: http://www.vwproblems.com/trends/ignition-coil/.

A problem with the malfunction of the coils on the 03 engines of vw gl turbo. The problem causes the engine to misfire, making accelerations difficult and continuation of the operation of the vehicle dangerous. I was unable to continue driving, had to have it towed and then was charged an excessive amount at the dealership to replace the coils, even though this problem has been prevalent in these engines.

Bought a 2003 vw passat 1.8t in may 2005. Since then, I have taken the car to the dealership for repair 4 times now. The car will all of the sudden start running very rough and the check engine light came on. The first time, they replaced a "defective" spark plug. Within a few days of getting it back, it happened again. They decided to replace all the spark plugs that time. It happened a third time and they did not tell me what they had done to the car, but kept the car for a week. It is currently in the shop again (now for a week again) because it began to run rough, developed a slow oil leak, and does not always start on the first attempt. I have not yet heard from the dealership what is causing the problems. I asked them to check everything on the car. I have also lodged a complaint with vw of america.

2003 volkswagen passat w6 2.8l car will not start or fails to run properly due to ignition misfire or excessive fuel flooding engine. Volkswagen will not repair. Car has been seviced with the best synthetic lubricants and has had extremely good care. The dealership told us the reason the car would not run was because the oil needed changing due to it being loaded with gasoline. The oil had been checked 3 days prior to the incidents and was at satisfactory levels and clean. The car had 6700 miles on the synthetic oil change and was not due for a 3rd oil change. The car has 11813 miles on it. The recommended oil change interval by the dealer was 10000 miles on the synthetic oil. If the car is failing to run and has allows severe gasoline contamination of the oil there are major problems. There seems to be many complaints regarding the reliability of these cars available through other web sites. The engine failing to maintain operation or misfiring while on the highway or if it fails to operate in an unsafe environment proves this vehicle to be a failure in engineering, and reliability.

Engine starts to stall and misfires in traffic. Dealer refused to change recalled coils on 8-15-03 . Contacted vw help line and they indicated that their records show that dealer replaced the recalled coils even though he didn't. It appears the dealer filed a false warranty service claim with vw according to the information they received. Dealer still refused to change coils on 9-25-03.

This vehicle contains 4 ignition coils, one of which failed. This part which is installed on many 2002 and 2003 vw's is prone to sudden failure and vw owners have been experiencing multiple and common failures of their ignition coils. Vw has redesigned the part but is only replacing failed parts at this time. When this part fails it causes the engine to stall or misfire badly and makes the car undriveable. This is certainly a safety issue if the problem occurs on a highway, causing the car to stall, or stranding a motorist in a dangerous location. I believe that vw should replace all the defective ignition coils with the redesigned replacement part. Thanks. Scc ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****770857****
