Default CEL on

friend of mine was driving his 98 1.8t manual quattro down the highway. he was going about 80, decided to take it up to just below 120. after he went above 115 he began to slow back down. as he was decellerating he noticed a CEL on...

car drives fine...

he's giac chipped, boost guage (he's running fine), custom exhaust, and a forge 007 DV......

any ideas?

Check the gas cap. Did he fill up recently?

Default As long as it is a steady lamp it's fine to drive for a bit. It's also likely it will go out if he

has the requisite number of driving cycles with no repeat of the fault.
If I was to bet, I'd bet he had misfires due to chopping the throttle ....

Default i guessed misfires, only during his high speed run

and since they wouldnt be happening now, the light might go off after a few times of driving
