Hi Im hoping someone can shed some light? After changing the timing chain on my Cooper R56 due to a broken chain guide, the motor is running really rough! I double checked the timing again incase I had jumped a tooth! But all good and cams lock down snug! I got 3 error codes on it P0014, P0015, and P2414. The 1st 2 refer to B Camshaft! My question is does B relate to Inlet or exhaust Vanos units? Im thinking one of the two Vanos units is faulty as i have already changed the sensors with no change,If someone can verify my conclusion and point me in the right direction it would be most appreciated! Thanks in advance!,
