Has anyone on here ever retrofitted the DPF? I know most people would rather get shot of them due to regeneration problems or power increases over 200 bhp but I think I could do with one. I have to say I don't like having to constantly clean the exhaust tips as well as creating a sooty smoke screen on a recent trip to Wales constantly overtaking slow cars (safely I might add!) as well as to compliment my facelifted 06 TDI SB with S3 parts (photos coming v soon!) by fitting straight tips instead of downward facing ones that I've got at the moment. I can regenerate at the minimum once a week by driving as required or via VCDS, but it's more the fitting, coding and I think I might need a new power module etc as I haven't seen any options to do with DPF anywhere on VCDS on my car. (Anyone with fairly new great working order DPF with looms etc I can purchase at a good price?) What do you DPF experts think?
