BMW Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** fault code will usually be caused by incorrect camshaft timing due to a bad chain tensioner or a stretched timing chain. If the engine is noisy I would suspect a stretched chain or collapsed tensioner or a fault with the camshaft adjuster.
Let me know if you have any questions.
The adjusters are at the front of the camshafts.
No, the adjusting units behind the plates.
Specifically the exhaust gear. You can try swapping the cam adjusting solenoids from side to side and see if anything changes.
