fine.... tonight i guess i will get it working. sorry. same question as other guy. how do you know if vvt fails. I have an amb engine code also so you dont have to look up locations here my xdf
You can usually see values out of spec at idle when there's issues with VVT in my experience. At idle cam angle should be 0 +/- a few degrees. A faulty tensioner, stretched chain, or low oil pressure in the head will cause angles out a spec in the negatives. Not to try to keep you using VCDS over ME7L, but the measuring blocks for camshaft angle are in the 90s.
