60g soot DPF cannot regenerate
HI
2007 V70 D5244T5 I tried to adapt values for DPF before trieng to regenerate. Half tank of fuel in the tank. There is 60 g soot. But the regeneration wont start. Two fault codes on the DPF - none on the temperature sensor on DPF, so it should work. Fault codes: 2B40 - DPF faulty signal 2B44 - DPF value I havent zeroed the DPF counter though - should I? Previous owner drived around with failed swirl flap, she said she'd done a regeretation once before, a year ago. Ive cleaned up and changed the swirl flap obviosly and made an adaption on it. Something else I should adapt after the change? Its time for service and I havent done that yet - thought to do it afte the regeneration. Thankfull fo ideas =) Last edited by Orchid70; Oct 8th, 2019 at 17:32. Reason: Added fault codes |

It might benefit from a blast down the motorway

It feels like the car is not quite responding, not in the higher gears at least.

So - I took a long drive to a friend mechanic, who helped me change the timing belt. We also changed the diesel filter - that looked like it was changed last time in 2012 - when the previous owner bought the car.....
And drove quite a bit in third and fourth gear in 100-120 km/h. Back at home - I could start the regeneration. The soot was 60 g at start. After one hour and 20 minutes - there was 6,18 grams left =) Well - the text remained in the dash: "Engine service required" and fault code for DPF faulty signal. So I tried to zero the DPF counter as well as adapted the pressure sensors for the DPF - and after that the fault code and text were gone and limb home was gone!! Noticed that during the regeneration a lots of fault codes occured. Couple for glow plug relay for ex. I was able to turn them off though. Is that something that usually happens during regeneration? |
