1999 Volkswagen Eurovan Repair Question
Mileage: 80,000 miles.
Is there a particular fuse to check for check engine light staying on?
Answer
it's possible that you may have damaged the computer with the pb blaster. but check fuses 1-18-117 in underhood fuse panel and fuse 102 behind lh dash.also check for a poor ground wire from battery as the pb stuff may have gotten between fhe end of cable .
What happened was when you washed/PB blasted the engine the ignition coil got saturated in moisture and caused a mis-fire.
The reason why the guy at autozone could not scan your vehicle was most likely because he was using a cheap generic scanner that cannot scan european vehicles.
stay away from the zone! they are people that couldn't cut it anywhere else. any that i've made contact with misdiagnose and try to sell anything to make a buck. autozone and vw/audi do not go together very well.
also if it's still a problem i'd seperate the suspected connector(s) and use a brake cleaner to wash the pb residue off,it may cause resistance and thus, the cel is on. do this for the connector side but be careful doing it to the ecm.
Tom Singo: How is everything? Were you able to get the CEL to go out? Were the suggestions here useful?
