VDC, I kind of figured that was the case, but I was hoping it might be easy. And the fact that a dealer told me the bill sounded “about right,” probably means it’s a bit on the steep end.
As for what they checked…I didn’t think to ask, and the invoice doesn’t mention that. The interesting thing about this is that this is a car I bought from my dad, and in the summer of '06, he took the car in with error codes PO443 and PO446. They replaced the “evaporation control canister” and that seemed to fix the problem (pressure vsv not opening and closing, failed canister assembly). Is that canister the same as the charcoal canister, and if so, shouldn’t it last as long as the car is on the road?
Are there a couple quick checks I could do to see if maybe it’s just a valve issue? Or is there a way to reset the monitors myself so I can see if it’s just a matter of the gas cap needing a good tightening?
