F11 Dpf Problem - High Soot Mass Error
Hello, maybe someone could help me...
There is an error: 245700 - Particulate filter system: Heavily loaded particle filter (exhaust back pressure high) There is around 45-50g soot mass and differential pressure sensor shows around 30-40 hpa on idle gear DPF regeneration, using bimmerlink, isnt working Also "Driven route since regeneration" shows 60 km....So it was not so long ago, and didn't do any better Any suggestion ? The car is used on HW at the most of accumulation.... |

Shorter journeys are not suitable for DPF regeneration, you need at least half a tank of gas and you need to be constantly doing at least 2,500 rpm and at least 40mph for at least 10 minutes consecutively, it should do the trick.

Well, it should gradually go away with regeneration... Here's what ISTA says:
1. Check oil level and change interval. Correct oil level or change oil. 2. Check swirl flaps. 3. Perform exhaust gas pressure check 4. Check diesel particulate filter (visual inspection to see if exhaust tailpipe and diesel particulate filter outlet sooty). 5. Perform regeneration. Only possible with constant-speed driving for at least 30 min. (The regeneration cannot be stopped with the corresponding service function for this fault). 6. Check intake ports and intake valves for sooting. Excessive oil entry from the crankcase ventilation can lead to sooting, especially with short-distance driving. |

So for now,
soot mass was around 45-50g differential pressure sensor shown 40 hpa / mbar on idlee and there was an error about too high soot mass Still regeneration wasn't go itself and there were no response on force regeneration. Status of rege was active / no active - temp didn't go higher than 450 After all checks I was on dyno to check power of the car, was decent - strong serial Before dyno test all errors were cleared. Later after test, in highway regeneration started itself and soot mass went down to 10g. Driven 3k km after dyno test, for now its fine. Also regenerations starting itself. Weird things happens... |
