well where do i start i have a 2002 mcs and have a big isue with lack of power.t started the car and a light came on the dash (DSC ) so i ran a fault check and found fault code p0341(camshaft sensor) so i orderd a new 1 and replaced a few days later and deleted code started the car and light was still on and took for a test drive and still know power. and fault code came back again, i booked car into bmw who had it for 3 days and change the cam shaft sensor again! still no power and thay said could be the ecu.any1 know of anything else it could be anything that might help

 

did you ever resolve this I am having the same issue?

 

this is a tread from the dead, but I had the same issue and the cam timing sensor was replaced and no issues since.
