    I’m getting an android phone later today and hoping to use the VAG DPF app to check the health of my DPF and moniter a regeneration if it needs one, the fans been running after driving short distances recently so I suspect it does.

    Quite a bit of info on how it works here

    https://www.briskoda.net/forums/topic/423341-vag-dpf-app/

    Has anyone had a play with this app?

    Yeah its actually quite good if you have an engine that the app supports.

    I thought I'd give it a try for the 3.0 TDI but its not supported, and having emailed them there are no plans to add it.

    Just had a try the other day with my CAGA engine, came up around 500 miles since the last successful regen, 15g of soot and 0.1 of ash and the dpf was 66% full.

    Went on the motorway at a pretty decent speed for about 10 mins and the exhaust temp was around 350 then the ecu must have gone into regeneration mode and it shot up to around 780c and the soot then dropped quite quickly to 4.5g and 25% full.

    The cars on 82K on a 10 plate so the dpf looks pretty healthy looking at that.

    No problem, I’ve been using my carista Bluetooth OBD connector so if anyone has one I can confirm it works with this app.

    Going to take mine for a 1hr run tomorrow, showing 16g of soot and 532km since last clean. Hopefully that will burn it clear.

    Well 1hr blast and it's now like this? Does that mean it's 80% full? [​IMG][​IMG]

    It’s not regenerated on that drive you went on, you know when it’s doing it becuase the exhaust temp goes up to about 600c and the soot starts dropping quick, then the time and distance will reset when it’s done.

    It is due a regen looking at that but it just depends when the ecu decides it needs one.

    I’ve read that you need a decent amount of diesel in the tank or it won’t regen, not sure how much truth is in this.

    It looks like you need to turn auto refresh on as well, go in settings and look for something like auto refresh or similar and turn that on then the values will refresh as your driving, i wedged my phone in front of the steering wheel.

    Mine started a regen when it was around 16g and I accelerated hard to a pretty decent pace 100mph plus (on a private road) for about 15 mile.

    They dont regen on a spirited drive I dont think. Just a steady drive at 50-60mph in 4-5th gear should do it.

    I think the regen miles resets after it’s done a full successful regeneration not a partial. Mine did the same the other day when the Mrs came home from work, it’s only about a 3 mile 30mph drive and it nearly did a full regen then.

    I think your right, it seems to look after itself even when you do short drives.

    Ive been monitoring this app quite a bit, from my findings the amount of.fuel you have doesnt make a difference, also really high speeds dont help. Ive tried belting it to get it to trigger at only 50% full with no joy. I think it does it when its ready, for me its been anytime after say 70%.

    Last time I checked it was at 82%, I tried putting my foot down to get the temp up but it didnt trigger. I then stuck to 55 cruise control on and it suddenly decided it was time, temp.shot right up and the process started, another mile or two and all done

    Hi,

    I don't have this app, but I've noticed with VCDS that the threshold for an active regeneration is noted as 'charge limit for field regeneration'. For me, this value is currently 22.77 Grams. The limit depends on the oil ash residue, as mine recently lowered slightly when the oil value changed to 0.11 Litres.

    Regards,

    Matt.

    From what ive read you can try as hard as you like to raise the temps to regen levels but you won't get far. The ecu decides when its time and injects more fuel to raise egt's enough to burn it off which is why you can sit at say 50mph whilst it does its thing.

    Under normal conditions no way would you hit 500 degrees + doing 50mph

    I did a scan and it was on 62%. Took it on a run down the motorway and on the second reading it was 10%.

    Mine was at around 70%, as soon as I clicked the cruise control on it started regeneration. Not sure if this was a coincidence or not.
