hi my name is ***** ***** i am chatting from Denmark
Hi Paul I hope you are well. I’m sorry to hear that you have faults stored and I totally understand how frustrating this is. So this code is suggesting that the diesel particulate filter pressure is too high which in most cases means it’s full and requires cleaning
Customer: replied 11 days ago.
The diesel particle filter bank 1 delta pressure shows 327,58 kpa while the engine is not running, could it be that the pressure sensor need changing
I suspect so that reading is way to high
Customer: replied 11 days ago.
the inlet and outlet are at 0 when the car is not running, when i start the car the delta pressure goes to -3xx kpa while the other 2 still are at 0
It should read 0 or very close to 0 with the engine off and ignition on
Customer: replied 11 days ago.
i will try to clean or change this, if this doesnt work i will ask again. thank you for your help so far!
Perfect. Keep Me posted.

Hi kevin, i changed the pressure sensor and tried to delete the fault codes but no luck, i tried to see how high the pressure was now but the computer wouldnt let me for some reason. the new fault code now is P2204-Nox sensor
Customer: replied 11 days ago.
The original fault code P246C is still there and P2204 popped up as well
ok so you need to reset the pressure sensor when replacing does your tool have this option will be under basic settings or adaptions
Customer: replied 11 days ago.
unfortunately it doesnt, i will try and find one that does have it
keep me posted
