I would first ensure that lambda adjustments are similar between banks. If lambda is malfunctioning, corrections will be high as well as lambda adjustments. If lambda ok, then only corrections will be high.

Not yet, probably this week. May change DME, remove and clean Vanos, check valvetronic function, replace sensor just for the heck of it and probably cylinder head out to check that gasket has integrity.

What are your exact error codes?

they have problems with the aluminium rings on the camshafts!
they cut into the camshafts and that in turns also a misfire.

get back to me and ill explain if so

Error code is just misfire, cylinder 5 though of late it moved to cylinder 4 and abandoned cylinder 5! Yes, we suspect a mechanical fault if not a DME fault. I guess with open engine we will be able to detect if its camshaft, or gasket related or any other mechanical faults.

You know there are tools to check compression and leakdown, which can save you lots of time, instead of pulling head off.

Compression was OK. Will try leakdown test before pulling apart for sure.
