Hello everyone,

I wonder if there is anybody out there, who could help me with a particularly strange issue with the DPF regen.

The car has been in the garage twice & had one forced regen (static) with new DPF sensor & one forced regen driven.

Both solved the problem for a short time.

The first regen solved the problem for around 800 miles, the second regen only lasted for 115 miles, before the engine light came back on. No amount of driving (hard) has changed the situation.

One other strange fault is the rear RHS door fault.

Any suggests gratefully received.

If everything electrically (incl. speaker) works on the rear door i don't see any problem there.
About the DPF: can you check the ash mass? or maybe the DPF is toast and needs replacing

From the past experience if it's the engine code with Adblue from 2014 then you issue may be related with Low Pressure EGR.
This is failing and not closing properly and during regeneration exhaust reading over the pressure sensors are not correct.

If don't have adblue try to monitor the DPF Pressures and temperatures during regenerations process and post it here.
