2011 Mini Clubman (base) - VVT Solenoid or Cam sensor

[dtolani]

Hi there. I have a 2011 Mini Cooper clubman with 42k miles on it. Ever so often it throws up the CEL. When I check for the codes it always says ‘poo15 - b camshaft position - timing over-retarded’ ‘bank 1’ In looking at various websites and videos online I am not sure it it requires replacing the A) camshaft position sensor B) VVT solenoid . Which one ? The one closest to the cabin looks like a pain to get out. The one toward the front of the car seems more Accessible, but is that the problem ? Thanks

You can get the rear one out with a 3/8 ranch and a shorty extension. It helps if you pull the PCV hose loose from the valve cover and move it out of the way. I would pull the both and inspect the screens to see if there is any debris. Hopefully you aren’t on the mini service plan and doing 15k oil changes?
