N47 Issue
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. 😅😅😅 Last edited by George89; 07-30-2024 at 03:53 AM.. |
