Friends,

I have problem with this car...after swiftec file car going with leser power, 1-2-3 gear is ok, but, on 4th and 5th gear the car accelerated by it self?? Strange stuf...I have tried to connect, disconnect egt, pressure sens...but no change, and not good.
Here are attached ori and swiftec mod file, can someone check or make properly DPF OFF file, with disconnected sensors.

Thanks in advance,
regards,

currently have solved one problem..loosing power...someone from colleague disconnect H2OS !

BUT still remain problem accelerating on 4th and 5th gear...only on theese gears, the car sets Desired idle speed to 1500 rpm...and car start accelerate over 55km'h by it self...(at same time acceler. pedal is 0%)
Strange, really...I have mever seen something like this, no DTC into ECU, no tempomat pronlem..

Could you try pulling the plugs of the exhaust gas temperature sensor and the DPF differential pressure sensor? After uploading the file
