As SmartBear says and others experience it’s not the predictability of doom of say the 35i HPFP, injectors, waste gates etc :tumbleweed:
:( Having just changed a failed HPFP in my 35i, I guess I'm now just waiting on the injectors and waste gates :cry: . Oh well, it's fun when it works...
Current: 2010 35i DCT
Gone: 2008 2.5Si Sport
