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!
