Hello.I have low boost under 2300 rpm and on slight acceleration have hesitations.Sure... without error code
When the car have low power the:
-MAF specified 30 kg/h
-MAF actual 50 kg/h...and that is too much flow throught MAF.
-Actual boost is lower that specified until reach aprox 2300 rpm...
-EGR pulse ratio 15%
Some times DME close the EGR 0% duty cycle and the car runs great without Issue MAF specified rise at 50 kg/h and actual same 50 kg/h,boost perfect.
The car have also DPF OFF.
The only thing i think... is EGR cooler clogged...
I have ista air mass test failed (Exhaust gas recirculation) but when DME close EGR test passed. 😅😅😅
