DPF won't regenerate - is buying one from a discount as good as from the dealer?
My DPF will not regenerate. I have tried forced regeneration in the garage, but it still won't budge. Should I replace with dealer parts which are very expensive. I could replace with a cheaper version from car part dealer or get it removed and cleaned professionally then replaced.
Readers have tried all three methods. The replacement aftermarket DPF tends to be the cheapest but most unreliable, so only do that if you plan to offload the car fairly pronto. Next best, the Ceramex cleaning process, but this relies on the DPF being removable and replaceable, not rusted on. The dealer price is almost always ridiculous and is one of the reasons not to buy a diesel car with a DPF.
