Looking for help with an annoying engine problem I have with my '08 328XI. About a month ago my "SES" light came on and my code reader gave me a "P0015" error code: "B" Camshaft position timing over-retarded.
Did some quick research and found out this could be caused be a bad cam shaft position sensor, so I replaced both my intake and exhaust cam shaft position sensors and the "SES" light when off. Then, after a week or so the light came back on again and was accompanied by a clicking sound in the engine. Both cam shaft position sensors I bought were OEM BMW from ECS tuning. However, assuming that maybe one of them was bad I switched back the old sensors because the clicking sound wouldn't go away...still nothing. The "SES" light has been randomly turning on and off, but now has been off for about a week or so. The clicking sound can't be heard when you first start the car, it is only when I step on the gas pedal and accelerate and then it increases proportionally to how fast i accelerate. Also, I have had several instances of stepping on the gas (while already moving) and my rpm's jump but the car doesn't accelerate any faster, THEN all of a sudden the car will jump and accelerate after a short delay.
Anyone have ANY ideas what this could be??? I have been trying to troubleshoot for about a month now because i refuse to go to the stealership. In my troubleshooting I also replaced both my vanos solenoid valves and still nothing. Any help would be much appreciated!
