'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.
