BMW DPF error reset
 

On a 2007 BMW 525d, the main thermostat failed - so the DPF regeneration did not start.

I have replaced both the thermostats and verified that the temperature now is above 75C.

Still no DPF regeneration.

I have been told many conflicting ideas - from driving hard on Autobahn (I did) but the error still comes up.

Car runs perfectly no problems whatsoever.

How would you fix this?


Any input appreciated

What DTC have you got?
