XZBMW  EGR off F31 N47d20c solution with DPF on
HI guys
I have question i want EGR off because of carbon build in intake manifold ... but DPF need to stay. So question for tuners i know its possible to switch off EGR but still functional in cold start and in DPF regen.. process.

I need opinion of that solution because close EGR will effect bigger exhaust flow thru DPF so will effect faster degradation and regeneration.

I know opinion are 50/50 that DPF should be removed too, but in this car need to stay.

appreciate all advice
