New to the forum but been a car guy for quite some time. Picked up an '08 135i a couple months ago and just popped a CEL.

P054B - Coldstart Camshaft B position timing over-retarded.

A quick search didn't come up with any hits. Used Torque App to scan the code. Not much info.

Anyone have any other information on possible cause/fix?

A search on NAM Mini forum shows:

P054B - VANOS, exhaust-side, cold start: No closed-loop control possible

But that is just a partial list.

Car is out of warranty but had all the recalls done and I had the history checked at a BMW dealership and it had no history issues.
