My first post so please be gentle, we've just bought a 2010 X6 3.0 40d from a local dealer, after driving only 3 miles in the car after picking it up we got a reduced power message on the info screen, dealers got the car back now says it's got the following fault codes
4DF9 throttle Valve Actuator position sensor signal
4530 charge air pressure Control deviation
3F25 charge air tube monitoring
480A particulate filter system
429A boost pressure control low pressure stage control deactivation
They've fitted a new throttle body and new EGR valve but the same fault seems to reappear and won't clear with auto logic.
Any ideas from you experienced people out there.
