Hi everyone,
My 335i just got out of its CPO warranty 2 weeks ago. My car which has run like a champ started running rough throwing cels etc. I took it to a nearby shop that works on BMWs and that I trust. They worked on it yesterday and ran diagnostics and have determined it is the fuel pump. They are getting this to me in writing and I have set an appointment with BMW. Will bmw try to charge me for anything else like their own $250 diagnostics etc? Curious if anyone has had an independent shop recommend the hpfp be replaced an BMW do it.
