Hi chaps. Was talking with a customer today, we were talking about diesels and stuff. He said a current vehicle of his, equipped with the Mercedes Bluetec platform, had some kind of aftermarket type air filter installed at some dealer. Apparently this modified the pressure drop in the intake, which lead to fuel combustion issues, which clogged the DPF, allowed soot to get into the turbo and cooked that too. When he took it back they ended up offering him 20k off a new vehicle because with that much alleged damage who wants to take up the tab on the labor cost of fixing all that? Sound plausible? I think so, but I can't sleep tonight without thinking about it, if it's true.
