2010 Mini Cooper Power Loss

Oct 2021 | 3 comments

This 2010 Mini Cooper arrived with the MIL on and a complaint that the vehicle lacked power since having the air intake system upgraded. The vehicle had numerous faults stored in the DME.

During the initial road test, there was no output from the MAF sensor or the B1S1 Lambda sensor. The FMEM saw this and the other faults and limited boost from the turbocharger. Scott Brown takes you through the diagnostics and repair.

    You never mentioned it, but I assume you switched the mass air meter around in the correct orientation?

      Hi Pete,
      Yes, between time marks 3:16-3:20, Scott describes how the vehicle was brought “back in, flip the Mass Air Meter around and take it out for another test drive.”
