N57 DPF regenerates too often
Hi all!
Can you help me? I have a 2011 530d xDrive (190 kW, 258 HP) My car wants to regenerates too often. I replaced all of the exhaust sensors, and I took my DPF to a specialist to cleaning. The specialist told me, the DPF had a very good condition… I deleted all adaptations, and registered a new DPF after cleaning with ISTA. But still bad, and I don't know why. The differential backpressure values the next: - When the engine off, just ignition: 22-23 hPa - When the engine on (800rpm): 30-32 hPa - When the engine off, sensor unplugged: ~ -400 hPa Is it not normal, right? Do you have any solutions? Thanks for your helping! |

My car is the same and regenerates every 550-600km when I drive in the city. At the highway regenerate in 800-900km.
What is your average regeneration distance? |
