    Frequent DPF Regen

    Hello everyone. Been monitoring a possible problem with dpf regen on my Seat Leon (EA288, CUPA) for at least a year now with a standard OBD Bluetooth dongle and VAGDPF android app. I was noticing the regens were a bit frequent for the extended long runs that I do everyday so decided to monitor them.

    Using the app, I've noticed that the soot mass increases normally in relation to distance travelled, but the car seems to regen regardless around the 90-110 mile mark. At this point the soot mass jumps from around 10 grams to 20+ immediately, indicating the dpf is full of soot which surely cannot be the case. I'm thinking it could be a sensor somewhere but there are no engine fault codes stored and no lights on the dash.

    Been looking at upgrading from standard obd dongle to VCDS fir a while and decided to take the plunge!

    Auto-scan from last weekend below, is there more detail I can provide from the VCDS that would help in this instance?

    Few things we would check here in our workshop that may not show up on a scan as preliminary:
    Fuel Filter - when last changed? (every 2 years MAX)
    Check for any minor boost/vacuum leaks
    Check to make sure injectors are coded correctly

    Any of these can affect how clean the fuel is burning and hence soot mass.

    Also, the soot mass is not constantly measured, only every XX number of miles/minutes running, so it is possible you have a bad sensor. We do replace a lot of DPF sensors causing soot reading errors on VAG vehicles.

    Hope that helps
    Regards
    Dan

    Hi SkilledMilk,
    What are the readings from the Differential Pressure Sensor KOEO and at idle?
    Regards HMC

    Thank you all for quick replies and suggestions.

    I'm at work currently and will get the differential pressure sensor outputs from VCDS when home. As an update, I monitored the mode-6 non-continuous tests using the Torque app on my phone on the commute in this morning (approx 65miles, almost all on motorway at 50+mph) and the following screenshots are the results. I've used the app to do this in the past and those tests have never been ok in the time I've been monitoring. I have tried googling the codes but have come up short with what the failed values relate to.

    As an aside, the mode-6 button on the VCDS software is greyed out and unclickable so for the time being I cant use VCDS for these tests.

    Uhm, this is not the Torque App forum.

    Please post Measuring Value data from VCDS.

    Noted, just an attempt to provide context! Home with VCDS in hand and the below are the outputs from the differential pressure sensor at KOEO, and at idle.
