Ya I totally understand wish I could explain it more but it's a vibration for sure.

On the other hand its pretty difficult to diagnose a vibration/hesitation without feeling it.
So from what I understand the vanos is just a bunch of seals/gaskets. Would this really cause a vibration tho?
After reading more info on vanos.. I believe my problem is just the outside ambient temperature not the actual engine itself. Because even on a warmer day the engine needs to warm up but doesn't exhibit this issue but yet it should if it would be affected by vanos. Am I correct?
