My lperg cooler was replaced beginning of last year and I've done around 4000miles ( was not used for 5 months over winter) and been reading thread each new post , I was waiting till I got a p401 again before deciding what to do next ,but am now thinking seeing recent data posts, are we doing more damage driving with a failed DPF ?
The soot recurulating in turbo , combustion chambers ?seem stupid we have a air filter in system,but it then pulls in contaminated gas back in combustion cycle due to faulty DPF.
I check tail pipe every drive and am still confused why I get sometimes very faint soot on paper wipe ,then next time it's thick black deposits? I can only think it's affected by regeneration process, with the crack in DPF opening up more after regeneration allowing more soot through?
Is it time to just bit the bullet ,
