This part is listed by BMW as BMW part number 13627805758 (13 62 7 805 758) and is described as the exhaust pressure sensor found after the DPF on M57 engines used in E90 335d and E70 X5 35d models. BMW now has a DPF cleaning system - it is described What is the DPF and how does it work? As stringent emissions regulations increase to reduce emissions, diesel engines use an EGR valve to reduce NOx emissions and a DPF to remove soot from diesel exhaust. Once the sensor values from the exhaust gas pressure sensor; The last successful regeneration can be read out by the diagnosis system; The following conditions must be fulfilled for a regeneration: The coolant temperature must be in excess of 75 °C; the exhaust-gas temperature before the diesel particle filter must be greater than 240 °C Still the DPF has the same back pressure. diesel particulate filter cleaning Either your DPF is full or a the pressure sensor isnt working well BMW 318d se auto 2013. Jump to Latest Exhaust back pressure sensor during diagnostic with Carly. 0d, when you are at WOT the pressure before the DPF peaks at around 480mbar.

But I'd still suggest further investigation, it could be the DPF but it could be a pressure sensor. DPF and some other sensors have just been replaced by MB. Excess back pressure on the turbo will eventually cause the turbo IF the exhaust pressure sensor is placed after the dpf in the exhaust system then coupled with a sensor before the dpf would give an indication of how blocked the dpf is. so IF the sensor is faulty it could mislead the ECU into triggering longer or more frequent re-gens and that could increase the chance or rising oil/diesel levels on dipstick I have problem with DPF filter sensors. The price of an SCR/ Cat is about $1500 from your "fwendly" dealer! My vehicle no longer needs the cooler, since air never flows through it anymore but 2) the cooler is where the exhaust back pressure sensor lives, so unless I'm taking a -Reinstall and check EBP readings.
