Down on power
My 650i GC has been acting up. No codes have been thrown, but it feels down on power and has been getting some consistent waste gate rattle at WOT. Could this be a vacuum issue or a balance issue with the waste gate controller modules? How hard are those to have diagnosed? Is it best done at the dealer or a private shop? Am I off base on what might be the cause?
Thanks! |
