Hi, I used the van last weekend and on route to campsite EML came on, felt like the van wanted to regen but engine wasn’t up to temp and I was in slow moving traffic. I scanned van and got fault code P245900 - DPF regen frequency bank 1. I cleared the fault and the EML went off but the fault code returned. I kept the revs high on the motorway and the van ran ok. Got home and the van did a regen on the drive. Fault code now cleared but the soot level only dropped 1g is still at 24g. Does this sound right? I thought it should have dropped to around 8g after the regen

Thanks for replying, I will need to check ash level when I get back on Thursday.
Post some screenshots of the app screen.
Updated screenshot with the van ticking over on cold start.
So I have driven the van a few times since last post on mix of journeys. The soot level seems to increase quickly between 15g - 25-28g at lower speeds. It does triggers regen and lower back to 8g and then resets but on slow roads around the Lake District it regen’d every 120mins even though only 30-35mile had been driven. Couple of examples from the DPF app.
Has anyone had this before? Wondering if a sensor is on it way out. The DPF has been cleaned by previous owner but assume no sensor have been replaced.

Similarities below?
Clogged DPF - indicated by Soot Mass Measured value being much higher than Soot Mass Calculated.
Please post VCDS engine blockmap files - please turn off the Stop/Start
1) ignition ON/engine off
2) cold engine idling
3) hot engine idling (after a minimum of 20+ minute journey
How-to create a blockmap file:
Note: only VCDS HEX-V2 or HEX-NET cables have the capability
Ignition ON
[VCDS]
[Applications]
[Controller Channel Map]
- Single Controller Address = 01
- Login or security access code: Leave blank
- Function: Measuring values
- Output: CSV file
[Go]
The result files (.csv) are saved into directory C:\Ross-Tech\VCDS\Logs
This is a screenshot of when the van was warm and idling. The soot mass calculated and measured are a similar amount unlike the other post. The DPF it self is clean in the tip with no soot present when I checked so I believe it’s working
