    Hi to all, this is a '09 Passat with a 2.0 TSI I've been solving codes one at time and now I have a misfire and multiple misfires code, however, the car runs, accelerates and feels really good. I did a live check with the VCDS while a friend was driving and I notice that when we stop at red...

    Hey all, After working on my 2002 1.8t Passat AWM, I am about to throw in the towel and send it off to the shop. I have been working on it off and on for a couple months. Here is the original thread on the PCV system and VCG fix...

    Okay- my daughter isn't shuddering and sputtering, her TSI is. It seem to happen irregularly. She took it to the dealership which told her she should run premium gas in it and charged her $300 for a fuel injector cleaning (and $50 to put in a half quart of oil). Problem was gone for a couple...

    I'm coming to you guys because I'm not really sure what could possibly be wrong. I've got a 2.0T with the BPY engine. At highway speed (60-70) and driving temperature (200 degrees), the engine will misfire if I apply any pressure to the gas at all. However, when I'm going 30-35 the problem goes...

    Getting the following codes on my 03 Passat B5.5 1.8T AWM. I have replaced the DV (diverter valve) and had no change in the codes. I have also looked at all the hoses feeding the turbo and do not see any cracks or anything to lead me to believe that any are bad. I'm not sure what else to check...

    I have worked on this care and replaced the coil packs, plugs and several of the hoses that work with the air pump. It is missing the hose from the pump to the one on the top of the engine. I just replaced the coil packs and cleared the codes. The check engine light was off for one day and it...

    Hello All, So I have been getting intermittent misfire codes and a pretty consistent Secondary Air Injection fault on both cylinder banks for an insufficient flow. I recently replaced all the upper vacuum lines, including the one to the driver unit. I also replaced all the PCV hoses and the PCV...

    Good afternoon - Passat threw up a code to change the Cam Chain Tensioner, so I did. Now I have a Cyl 1 misfire. Swapped plug and coil from Cyl 2 but no change in how it ran or code. Measured power at each injector with the engine running and had signs of voltage on 2,3 & 4 but nothing...

  14. Volkswagen Passat CC Discussion
    Dear All, My 2012 VW CC sometimes can start, sometimes can't, and sometimes it turns off very quickly after it starts. It can stop quickly in the middle of the road. The dealer checked for two weeks and came out the conclusion that it is caused by timing chain. There are also other lights on...
