Rough idle near stall, once SAP cuts out in cold weather

M62 doesn't have valvetronic uses regular vanos.

Are you getting error codes?

Look though your scanner for cam position. Should have a requested and actual. I can plot a graph overlay with foxwell scanner and it's very helpful in finding problems.

Do you get a rattle in you engine at at start up that fades away? M62 notorious for having problems when the chain tensioner sort fails. Often it will rattle at start up but when it finally throws a code it's usually a timing error when the cam advances in it's own do to slack in the chain.

I could see this leading to bad idle. Similar to soft fail cps.
