Hi I bought a 2006 mazda 6 143bhp a few weeks ago after smashing my old mazda 6 in a accident. Anyhow I picked the car up from London sold as seen and on my way back home I had the engine light came on as well as the car skid light I also noticed the car was lacking in power but still I could comfortably travel at 60-70 mph. But if I tried to speed up my foot to the floor and the car would very slowly increase in speed which I find odd. On returning home I have noticed that I don't get a dpf light when I 1st turn the key in the ignition and have never seen a dpf light since. Could that mean someone has had the ecu remapped and removed the dpf recycling program from the ecu. I tried the wire trick to force regenerate the dpf but it wouldn't regenerate. I travel a 35 mile round trip to work everyday so I'm pretty sure the dpf isn't blocked but with no light I'm not sure can anyone advise me on what to do as I don't want to go to mazda and pay their silly prices to sort out my lovely car. P's the code I'm getting on my code reader is p242f regards Clyde
