I have a 2012 x5 5.0 with only 17,500 on the clock, and I think I'm starting to have issues related to this CCP. I've been getting "engine power reduced light" every so often, that goes away after restart, my exaust tips have black soot on them, I smell sulfur from the exhaust on during colder weather even at idle, and lately I believe the performance of the engine has reduced quite a bit.
I took the car for service back in December of 2014 and this is what they did:
• Cabin filter change at BMW dealer (2 filters)
• Brake flush
• Stored FC 2A7D Vanos solenoid Bank 2
• Performed Vanos test - OK
• Performed chain tensioner test – OK
• Oil found 2qts low – top off oil
• Clear FCs
• Recall 99BMZ0001
This was before the CCP, but so far BMW has not contacted me regarding it. All the problems still persist, and I have scheduled an appointment to take it for service on May 15th. Hope it will be more useful this time around.
Look at the amount of soot on my exhaust tips, and this is only 17,500 miles, always fuel up with premium.
