Hello!
2017 G31 540d.
Previous owner had short trips a lot. Mine have been long and I am not afraid of the throttle pedal so to speak.
When I bought the car it had 284C00 and 341D00 - Exhaust gas temp codes from DPF and CAT.
DPF temp would NOT reach above 110C, no matter how I drove. So I ordered BOTH, CAT and DPF temp sensors as genuine BMW parts.
They were a bit of pain in the ... to replace so that's why I changed both at the same time.
Issue is that the problem STILL exists after replacing the sensors.. DPF temp WONT go above 110C no matter what. It hovers around 50-110C when driving. No DPF regen is possible because ISTA says that at least 220C is needed for it..
All other temp sensors seem to be working correctly (SCR, CAT, EGR temps)
Soot mass - 60g but pressure is ~5 HPA on idle? Is that a bit weird?
Any help?
