Hi, I scanned my car today for free at Autozone, It's 1998 A6 2.8 Quattro
Here is what I got:

p1250
p0102
p0442
p0441
p1857
p0322
p1426

The only one I know of is 0441 - broken purge valve. I had problems with that for a while now, It was making crazy knocking sounds at idle, I thought it was really bad valve issue, but it turned out to be purge valve. You can hear it from inside the car =)

I was driving with it like that just fine, though a few days ago while accelerating CEL came on and it's on all the time now. I don't see any obvious problems with the car, seems to run just fine (except for purge valve, it does not knock anymore)

Can anyone pleace describe what those codes are and suggest some steps tp fix the issues?
Thanks.

 

p1250 - Fuel level too low - get your butt some gas
p0102 - Mass or Volume Air Flow Circ Low Input - ?
p0442 - EVAP Emission Contr.Sys.(small leak) Leak Detected
p0441 - EVAP Emission Contr.Sys.Incorrect Purge Flow
p1857 - Load Signal Error Message from Engine Contr.
p0332 - Knock Sensor 2 Circ Low Input
p1426 - Tank Vent.Valve Open

Sorry I can't be of assistance with what they all mean.

Thanks, this is something.
I've found some not OEM purge valve for 45$, thinking to order. OEM cost 85$
