330d hesitation
2006 330d had dpf light, check engine light and low down hesitation on acceleration.
Local indy changed maf sensor
Still hesitation and dpf light with occasional check engine light
Had 3 dpf regens by indy
Changed thermostats myself as coolant temp low
Still hesitation, dpf, check engine and hesitationn
Changed map sensor, still same
Cleaned egr valve, still same
Back to indy removed inlet manifold, cleaned, changed all glow plugs, rechecked maf, removed and soaked,cleaned dpf overnight, refitted.
Dpf light gone, still hesitates but less so, and still occasional check engine
Light usually at idle.
Car has evolve switch remap over 2 yrs ago Aand run like a dream till recent.
Switch unit reports error code p3ff0 but unsure what this refes to
Any ideas out there, next step is back to indy, but they may suggest 1500 quid new dpf. Not sure if this is the problem. Have done some long runs recently and no dpf lights. Resetting general check engine light using switch device and always same p3ff0 code.
Any ideas, comments,,similar expeiences
