I have a 06 Jetta TDI with the BRM, I have noticed every once in awhile I'll start from a complete stop, in 1st around 2krpms I will hear a weird knock, and the turbo doesn't build boost, I'll hit 2nd and turbo builds boost and the knock goes away. I thought that it was torsion value related, I recently changed the timing belt and never checked the torsion value. I checked it today, It was at -5.4 I set the torsion value at -.5 and I still hear the knock.

Thanks,

Dirtymax

I know the cam had one exhaust lobe showing wear, when I replaced the valve cover I looked for cam wear, but I haven't even driven it a thousand miles yet. How can I check the DMF? I do feel vibrations when I'm going like 55 and higher.

There are YouTube videos that explain DMF failure better than I can with sound.

Maybe a axel?

Thank you, probably just get a single disc and oil pan while I'm at it, it's got two patches on it that like to leak lol
Check the CV Axles. I just replaced the CV Axles in my 2006 BRM because when you put the engine under load, it would wobble like crazy but would go away if you maintained speed on a level surface and that wobble is gone now completely.
