'Great', I hear you mutter, 'Another newbie with a DPF question'

Well perhaps a slightly different angle. Given favourable conditions, by which I mean regular long runs fast enough to regenerate the DPF, and use of premium fuel and/or Millers or similar additives, and rigorously keeping to Jaguar maintenance recommendations, how long should a DPF last? Is it something that no matter what will eventually need replacement, or does a pampered DPF last the life of the car? Specific car I am thinking about is S-Type 2.7, but obviously DPFs are present on numerous other models.

I have not heard of any needing replacement unless blocked or for some other reason. Trev here may have more of an answer, hopefully here will comment here shortly

Weekly italian tune ups in 3rd gear up the dual carriageway will keep that maintained well. Millers works to keep the light off but it really needs those revs up, and don't be frightened to get those revs right up.

 

hi

if run in the right conditions they should out last the car

but there not allway run at the right temp so can block up, theres companies out there that specialise in cleaning them, but only short term fix if cars not run right or has issues

cheers
