Hi All,

Have a 2007 335i with about 80K on it. Serviced by BMW. 93 octane or better only.

Car's begun hesitating/staggering under acceleration. Noticeable anytime I roll the throttle on. Especially in 5th & 6th gears. Sucks.

Talked to local BMW dealership service writer. He told me it's classic carbon build-up issues associated with direct injection. He told me BMW will address the issue under the normal 3 years/50K warranty but not under my CPO warranty.

Anyone had any luck "motivating" BMW to fix their cars at BMW's expense? If so, can anyone direct me to the correct contact person at BMW?
