Im considering removing the dpf filter! Im going to give the jlm cleaner a go first but despite my efforts the light isn't going to go out and i suspect prolonged use is going to knacker the filter if it hasn't already! I've glanced on some companies. Found this one dpfdeletion.com. Deletion seems to be the most cost effective resolution, although I don't like the idea. I'm concerned that its going to spoil the car if it ends up with a poor re-map, loads of black smoke etc? Any suggestions for good companies at competitive prices in the Derby area?
