    Dpf filling up too quickly

    Hi I have got 2015 Passat 2.0 TDI with 133k miles. Recently bought it and since I have noticed that dpf regens at least twice in a day. It’s happening roughly every 50-60 miles. It will fill up to 50% but then it jumps straight to 100% and starts regen. Regen process completes as normal and spot reading goes down to 5%. Any ideas why dpf filling so quickly? Any help would be much appreciated in advance.

    You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

    You can check to ash/soot content.

    It also depends on what type of driving you do, short journeys aren't good.

    Thanks for the reply mate, I am a taxi driver so journeys are mixed but I do school contract Monday to Friday where I do roughly 90 Mile round trip.

    The ash mass is too high, the DPF needs cleaning and then a forced regeneration plus a new genuine pressure sensor calibrated to the car, aftermarket ones are useless.

    Can you use old DPF sensors with the replacement DPF?

    Got it check mate and came back with no errors. As I said before car drives fine apart from too much dpf regens. Doesn't show up any errors on the dashboard as well.
