Need some advice, ive recently bought a tuning box for my 2.2Di
The unit plugs into the Diesel common rail etc
Initaly it felt great straight away a improvement but within 7miles of driving it I found that now and then changing between 2 & 3 gear it felt the engine was pulling back, but once into 4th it was fine
Is this the ECU adjusting?? Should I reset the ECU following the DIY guide on here??
I havent had any limp mode errors etc just this strange holding back problem
Re: Tuning Box Question?? Called the supplier and he stated to try different setting which i done, again the car was fine at first but once it got to running temp same problems again, so at least i noticed the problems happened once at temp
Call them back and he asked about my air filter, i replied i have a K7n panel filter fitted, he has requested I try a standard one so ill buy one
However after having the usal chat about the filter how many miles it done, when was it put etc it got me think and i remembered it was one of the first things i changed a year ago, so it took the filter out and the top looked fine, so i then removed it and under neather was a right state it was almost black so i have removed it and cleaned it now im just waiting for it to dry out and ill try again, fingers crossed
