    DPF issues, regeneration every 400 km

    Greetings fellow VW&Audi lovers,

    As the title suggests, I'm facing a problem that might potentially cost me a lot of money so I'm hoping someone experienced this same issue and can share a few words of advice with me.

    The DPF light started coming on a couple of months ago intermittently, ~every 2 weeks or so, but the problem has gotten worse and now the light comes on every ~400 km or so and field regeneration is required. The car will give an advance warning sign that the light will come on soon, it will rev higher than usual at idle and the rev counter needle will jump a few hundred RPMs when bringing the car to a full stop while driving.

    The dealer performed a forced regeneration after which they informed me that I 'probably' need a new filter, which is 2 thousand euros plus labour. Naturally, I went to see a couple of mechanics who said that new DPF will not fix the issue and that the cheapest solution is to delete DPF altogether. I don't want to contribute to pollution and I'd like to stay on the legal side as well to be honest.

    I haven't performed chemical cleaning but I have a DPF cleaner product at hand which I haven't used yet, but I'd like to know if that could make any difference first.

    Big difference between calculated and measured value usually points to a problem around the G450. The same value of diff.press. with eng.off and idle is problem, not mentioning that with eng.off it should be zero (is the value increasing with increasing revs?). I would check suplly and signal voltage for G450 (before changing it). After solving this problem might be good to correct/edit the ash amount in accordance to the diff.pressure at different revs. And usually - the more "miraculous" cleaner is, the more useless as well ... Proper cleaning usually isnīt possible without removing the DPF (and some "wet" methods works fine, but the the most common fault is not fully dried, then the moisture can destroy the DPF...IMO the best is "dry" method/oven with controlled temperature).

    Sorry, i made a small mistake. With Eng on, it jumps to cca 4.40 and increases with revs. Thank you
