    Was drinving home from work the other day and got the "emmissions workshop" with CEL. Checked the vacuum hoses, they were fine. Changed the air filter and screen, they were really dirty and the screen was loaded with crap. CEL and emmissions workshop still was coming on for a day or two...

    I know there have been a lot of posts on here about this, but I am just not getting it. My car runs like crap, revving and nearly shutting off when cold started. While driving, it will run fine except under acceleration when it misses. If I let off on the gas and then try to accelerate again...

    I just got a used 2000 1.8t Passat (i believe it is the ATW engine code) about 2 months ago. The car seemed like it was well maintained and is unmodified. Engine light went on and I got the codes P1128 and p1137 read at autozone. One is for too rich and one is for too lean. After reading...

    98 Passat manual, no chip, pretty stock. I researched it a bit and found that most likely it's a MAF issue. I Cleaned it with electrical parts cleaner and a ziplock bag, but still got the code and the car still hesitated at WOT. I disconnected the MAF and the car runs much smoother, no...

    A couple of months ago I got my first CEL(p1128) and quickly fould the culprit to be a break in the vac line connection at the front of the intake manifold-cleared it, no problem. Last week the code returned so I decided to replace all the vac. lines as they were surely due. I could not source...

    On Friday, I decided to purchase a replacement Air Filter from the dealer, for my 2000 1.8T B5. However, because the service center was about to close for the day, I was told to make an appointment for next week. I happened to see one of the VW mechanics outside on a cigarette break. I asked...

    I joined the CEL club about 2 months ago and the problem still persists. I have a 00' 1.8T wagon with 67,000 miles. The engine was running fine and didn't seem to have lost any power so I have been living with it. Finally took the car to Autozone and they came up with a P1128 code. Other...

    I am consistently getting the "Bank One is lean" message with my VAG-COM, after a CEL. Does anyone know how to level out, or adjust "Bank One" to alleviate the problem, hence, stop the CEL from coming on? Thanks - Kevin

It all started after I changed the oil, but I don't think that was related.... - After driving for more that 30 minutes my car will only boost to 6 PSI (I have the neuspeed chip & usually boost at 15 PSI) - The next time I turn...
