Hi I have a 07 220d with 130000 odd on the clock, the car had the DPF removed a few years back and deleat from the ECU, haven't had any issues with the car in that time but recently I got the check light, checked with techstream and had the falut code p2002 diesel particulate filter below threshold bank1, after checking the numbers on the computer I checked both pipes to the differential pressure sensor, both where clear so I assumed that the sensor it's self was faulty. Replaced the sensor but got the same reading on techstream, tried disconnecting the sensor completely and checking techstream again and I'm still getting the same reading with it not connected!
My next thing to do is check the wires to the sensor but I'm not sure what reading I sould expect as I can't find any clear info .
The picture below shows the reading I'm getting regardless of witch sensor(New or old) and the same when it's not connected at all
Any help would be greatly appreciated , thanks in advance
