Car won’t perform re-gen if

  1. Engine temperature does not reach over >75c, and stay over this for a period of time (20/30 mins)
  2. Some Fault codes are stored – Mainly and Ironicly the DPF fault code it


Firstly I installed inpa software on my laptop. The software is in a mini dvd that came with the package. I read fault codes and cleared them. Within a few miles drive I plugged in and checked again, they where back. I guessed these codes where stopping the car regenning and it was stuck in a loop.


How to do the BMW PDF re-gen

– I engaged the engine temp in hidden OBC so i could see temp.

– Plugged in laptop to car (battery fully charged)

– Went for drive on M5.

– Engage Cruise Control – Adjust car to over 50mph so engine temp runs at over 75 – my temp was reading 76 to 79

– Every 10’seconds clear the fault codes or take a passenger and get them to keep hitting the clear button on your fault code scanner.

– Look at your OBC temp reading.

– After about 10 miles my temp started rising and peeked at 93c, this is DPF doing its thing.

– Rear view mirror = sooty clouds occupied by eggy smell later.

– Exhaust tips sooty.

I suspect the EGR thermostat was the initial culprit but once it throws the DPF warning fault codes keep the car stuck a loop. I noticed the car was storing the dpf code before it was reporting it on the dash when i was driving too. So need to keep clearing codes obsessively when driving..
