Hi,
I've dpf issues for the past 9months on my 335d. So far I've had the dpf replaced, small turbo, several pressure sensors, both thermostats. My issue is that I keep getting too often regens, every 100/130mls or so. I used to get 300mls between them. All my issues started when my swirl flaps where removed. Was only getting 40/60mls between regens. Got these put back on (after trying a new dpf and small turbo) and got to where i am now. My mechanic is pointing at my remap. He sees the exhaust back pressure go above 250 at full throttle. He's thinking that going over this threshold sets off an early regen cycle. Recently i'ved had my dpf block up and need a forced regen after taking my car out for a serious booting it session. So clearly I still have a fundimental problem. Going to see what my tuners can do but can u offer any other advice, bar dpf removal......
Thanks,
