Fuel additives are supposed to degrade catalytic elements from what I can remember reading, though I suspect many members have used the likes of Millers and not had any problems. Certainly I doubt infrequent use is likely to cause any damage, that said I was poised to buy a bulk load of the stuff from Ebay then decided against it. Ultimately if the problem is not solved, I'd certainly look at DPF removal as opposed to replacement. There is a thread on here somewhere if you search, the effects seem largely desirable, though keep your old DPF in case of future change in emissions for MOTs. I think they can be 'recharged' by cleaning off the car... ??do I remember jet washing them.
