Hello, my BMW E91 320D N47D20A Pre LCI (2008) with 25,800km on it. It's driving me mad now. After days of troubleshooting i now need help.
I'm having DPF issues, it simply wont regenerate. I have tried to drive cross country trips. rev 3k rpm 10-20 minutes on highway and clear codes as i go but nothing is helping.
Bimmerlink is reporting around 46g soot. One workshop suggested me to replace exhaust gas pressure sensor and then take one cross country trip (had one planned anyway) since i had fault code on it. I replaced it and cleared all codes and went on that trip but nothing happened. I get fault code 480A.
My thermostat is showing good temps 90c. Exhaust Gas Pressure sensor is calibrated as i registrered new DPF with ISTA. Did one exhaust counterpress test and on 2k rev max value was 75mbar. Mine was showing 141mbar.
If i try to go on highway with 3k rev for 10-20 minutes. Fault code 481A is showing up but then gets removed and is not present when i restart engine.
I have also tried to request dpf regen with both ISTA+ and Bimmerlink, tried additive in diesel to lower burnt off temperature but nothing is working. I don't know why my dpf simply will not regen. Exhaust Gas temperature is about 300-400c when 480a is present.
If someone knows how i can manage to get it to regen or what i should look at. It would help me alot! Thx
