Good morning all.
Anyone know what the back pressure means at 8192.0 with the car off? According to Gemini it means faulty wiring, it thinks it's the female pins which connect to the dpf sensor are not tight enough. I have checked the voltage which is 5v. Please see attached.

Thanks, I suppose the cheapest option is to buy a new dpf sensor and try that first.

Back pressure
I think I got that conversion wrong , 10000 hpa is 1 mpa so that would makd it 0.8 mpa which is low/essentially zero , its usually listed in mpa.
Whats the issue , looks like its full after only 22 miles is it running bad you need the pressure when the engine is running which should be under 10 mpa , ideally low single figures.mine can be over 50 at idle and car is losing power up the revs and wont regen due to high back pressure.
