Re: Sudden regeneration CRLB
I think that regeneration is being triggered by measured soot mass which you do not see with this engine group selected - try to use vag com or try to change for different engine group in the app - like CFFB and then you will see measured soot mass values. I have the same issue still and still do no...

Re: 2.0 TDI CRLB frequent regeneration
Hello again, My problem remains unsolved and is even worse - now regenerations starts every 30-40km when driving in city. EGT is still an issue, even on original software is too high. I think that the problem is cause either by oil in the chamber or DPF which is somehow broken and gas does not have ...

Re: 2.0 TDI CRLB frequent regeneration
Hi, Thanks for your reply. Regarding differential pressure - it increase further... on the clean DPF (after reg.) max load increases pressure up to ~200-250 hpa and up to ~350 when dpf is full. What i also observed is that when engine (and dpf) is cold pressures are rather good. The problem starts a...

Re: Is my DPF finished?
Hello everyone, I am pretty sure, that the reason why calculated soot mass jumps from 5-10 to 24 is measured sott mass which is not shown in case of some engines. Please use VCDS or some other software (or switch engines group for a while in the app). I have the same issue in CRLB engine. As already...

Re: 2.0 TDI CRLB frequent regeneration
Thanks, The only problem is every workshop i visited (including official VW) are looking for the errors. If there is no error found then the only suggestion is to replace DPF for a new one... When i was checking the web i found some posts suggesting that EGT sensor may be the reason. Mine does not r...
