I'm asking this question on behalf of a good friend of mine who lives in a fairly remote town and is not very computer literate. He rang me yesterday, because he thinks I'm a car guy and can help him.

He has a 2003 VW Jetta that he wants to sell. The car has 110,000 miles on it and runs perfectly.

For the past 50,000 miles the engine warning light has been on. My buddy is sure this is because of an electrical glitch rather than because of an engine problem—because the car runs flawlessly.

He took it to the nearest VW dealer (200 km away) and was told the car needs new a "injector pump" and that this would cost $3,000.- My buddy thinks this is BS. (I guess he thinks if the injector pumps were gone, the car wouldn't run as perfectly as it does and has for 50K miles.)

Any advice from the brain trust? Clearly the car will be hard to sell with the engine light on. And he doesn't want to disconnect the light for obvious reasons. Anyone run across something similar???
