  2. Volkswagen Passat B6 Discussion
    Hi guys, new here but I need some help. Recently bought a 2006 B6 and was working fine until I noticed that the oil filler cap neck broke. As per a post here, I just took the cap off the neck and screwed it in directly to the engine. It fit! Then I noticed a steady check engine light. The...

    My 02 1.8t AWM would run fine till it reached around 3400 rpm then it would rev, epc light would come on and I would be in limp mode. Ross tech program showed G187, G188 and adaptation not started, no signal. At first I could delete the codes and the engine would act normally, but that quickly...

    2003 Passat W8 I was curious if any VW or Audi A8 A6 4.2l owner in here has ever had an exhaust leak in the mid section pipe union clamp and can this type of leak after the cats and o2 sensors cause erratic codes everytime?

    Guys, I'm a CEL with DTCs P0507 and P0171 on my 01 1.8T GLS w/ MT. I have also noticed a very high pitched whine on start up and corresponding high rpms. When the whine stops, the RPM drops down to normal range (about 900-950 rpm on my car). Driveability and MPG seem normal. I know this...

    alright, you guys wanted to know what my CEL light was on for when i put up the pic of my fuel mileage. sorry, but your predictions of a faulty MAF were incorrect. Now I just have to figure out what exactly is causing these codes. 2 Faults Found: 16815 - Warm Up Catalyst: Bank 2: Efficiency...

    I have not gotten a CEL for a long time, but I just happened to scan today. I got these message for all modules except for 1 (engine) & 56 (radio) which also happens to be the first & last in the scan. I have been using this OEM VAG-COM for a few years without any connection problems with a...

    Can you believe it. I turned my car in to the dealership for their second try to fix multiple HVAC flap positioning motor errors. The mechanic must have managed to erase all the DTCs and therefore refused to touch the HVAC at all?!? He he - the DTCs will return again when the car is due to 120...

    16486 P0102 Mass or Volume Air Flow Circ Low Input 17956 P1548 Boost Pressure Contr.Valve Open (N75) The very right block of MB033 was 0.1%-0.8% (760rpm-3000rpm) which I was told wasn't good even though in MB032 both blocks were in the 4%-7% range (within spec). I'm just going to get a...
