• Seat Leon FR - Seat Leon FR DPF Reoccurring problem 12 Dec 2012 (Forum)
  Now I'm no expert, but our Seat needed the DPF to be replaced as it was full and couldn't be regenerated. Nearly £1000 later, new DPF, the light came on again, managed to clear it out using the usual advice. Few days later, light on again and into limp mode.
• Peugeot 307 - DPF Removal 24 Apr 2011 (Forum)
  Due to test driving in the snow we didnt notice that the car was down on power (wont make that mistake again!) Anyway I invested in a diagnostic and replaced the MAF and cleaned the DPF filter. However as I work in town and have a 40 min drive though town 2-3 times a week the DPF isnt getting much chance to regen and is slowing my car down again. I'm thinking about just getting rid of the stupid DPF filter and solving all my problems.
