Hello everybody, I have a Octavia Mk3 2.0 (MY2019) with SCR system (AdBlue). I have been monitoring the DPF for some time with VagDPF and I would like to know your opinions. Currently in Oil Ash Residue the value is 20.71g (same value in VCDS) and the car has 45546 miles. I don't know why, but I have the impression that the value goes up too fast. For example with 44946 miles I had a value in Oil Ash Residue, of 20.45g. Doing a calculation it turns out that the value has gone up 0.26g in 600miles (0.00043g/mile). I usually make short trips of 32 miles with 15% city + 85% highway. I always keep an eye on the VagDPF and try never to interrupt the regeneration. They usually start when the Soot Mass Calc value reaches 24 - 24.5g and I do them on highway with 4th gear at 2000-2500RPM. I have looked at the upper limit of Oil Ash with VCDS and it is 80g. Using the values from the calculation, theoretically with 0.00043g/mile, I can get to 184000 miles with the Oil Ash value at 79.73g. I don't know if it's a very good value. As a side note, I always use Shell V-Power, BP Ultimate fuel. Sometimes I use normal fuel but I add AR6900-D MAX additive (1ml/L). As it consumes little AdBlue, I always use OEM and 0W30 oil (Shell, Ravenol, OEM). I don't know if this is relevant, but I tried the Carista app and "playing" with the app, I accessed the "Emissions tests" menu and by mistake☹️ I pressed the "Reset button" and since then I am not calm. I don't know if this could have affected some parameter of the ECU regarding the DPF. I have performed several scans with VCDS and I have no fault codes. Many thanks Best regards🤝
