My car threw this code yesterday when driving home on the thruway doing approx 80-85 and after 3 hours of driving. i looked it up today and erased it, and after 20 minutes of driving it hasn't popped back up yet. Has anyone had this code before, and what could it possibly be? i was thinking maybe changing the air filter since i am in the northeast and they salt the roads like crazy, but i'm not sure. any ideas?
thanks

 

2.8 or 1.8?

You got a CEL with that right? Probably the maf.

 

1.8T quattro, sorry

MAF

 

Dont waste your time trying to clean the maf unless you use an aftermarket cone filter than might have been over oiled.

 

thanks guys
