    Thread: German Guy has problems with his 2006 2.5 Jetta V

    1. 04-19-2012 09:55 AM #1
      Hi,
      first I wanna excuse for my bad english and for not finding any thread that could have helped me.
      I just need some help or advice for the following problem:
      I bought a 06/2006 2.5 Jetta (150 hp) with 126000 km and the control light of the engine electronic is lights. I checked the problem with the laptop and found following problems: misfirings in all of the five cylinders and air leak in the intake of the engine. I changed the sparkling plugs -> no difference. I broght it to a mechanic and he could not find anything too because he got no information about that angine in Germany. But he coulf find out (he contacted VW) that the sparkling plugs werde changed at 102000km and at 108000 km and also the ignition coils were changed. At 106000km the fuel pump has been changed and the injectors have been cleaned (all the stuff was done at a VW workshop).
      Yesterday i checked all the cables at the engine and the hoses but could not find anything.
      When i drive and hold my speed theres a clack from the engine but really high and the engine jerks a little.
      I really excuse for my bad english and for not finding any thread that could help me but I hope some of you can send me a link where I can find a solution or advice where I could find so. That would relly help me.
      Thank you in advance!

      I'm thinking maybe the MAF has gone bad. They are notorious to go bad.

      The MAF sensor sits on the big air intake pipe. You can't miss it.

      Yes right between the air filters and the intake. I pulled the sensor on it off and there was not really a difference... That could cause misfirings because of passing on wrong results to the engine control unit?

      Yes, the wire inside the sensor is the problem. Before replacing it, you can remove it and try cleaning it with a spray cleaner for MAF sensors. A good auto parts store will sell this. At 126.000 km you might just need to replace it, but cleaning it could work.

      I wonder about the air leak reported by the computer. (?) Did you find any loose clamps or bad vacuum lines?

      @brian81: Thanks for the advice, but neither cleaning nor replacing helped. But what makes me curious is that the engine runs the same way when the sensor is on as when it is pulled off. Regarding the air leak: I couldn`t find anything... This week I had to replace the air compressor of the air conditioning, so i removed the whole front to see if the vacuum lines are okay and to replace that compressor. Air conditioning is running now, the only problem left is that noise and jerking by the engine when i hold my speed.
      Thank you for the answer and for not criticizing my english!


      @mhjett: It was an imported car and driven by a german guy who had an accident which was pretty easy to repair. In addition the prize was accectable so is bought it. No indications about engine problems by him or the seller.

      Could any valve be the problem? Or the EGR?

      HAve you checked the coil packs? I had something similar with another car in the past and it ended up being a spark plug wire. I also know that here in the U.S. we had a recall on the coil packs.

      Have you provided anyone with the CEL error code?
