hi! I have file with DPF, MAF, EGR off, car is in limp mode, but in ecu no faults... checked with idutex and autocom diagnostic, nothing... only before some time was fault 1320 Air mass meter faulty signal, and then car was in limp mode, after I put this in ecu, there is no faults but car in limp mode and diagnostic shows Air temperature inlet MAF -40.04C, someone can check maybe MAF is incorrectly off?

are you sure that you uploaded a file with same checksum to your car? if car recognises wrong checksum it won't start or it will, but in limp mode only. you can fix checksums with WinOLS or ECM Titanium for example. Also Kess v2 and similar flashing tools should have this function built in.
