powerless passat 2001 AVF -96kW TDI
No power under 3000rpm. Engine goes to limp-mode when using higher revs. MAF (actual) is always lower than MAF spesified. Charge pressure is ~2300mbar at max. Car has driven 190Mm.
I changed brand new:
-"Air Mass Meter" MAF(I tried with two pierburg and Bosch)
-N75 solenoid ventile for turbo charger
-garrett turbo charger
-katalysator is OK
-EGR is OK
-intake manifold cleaned
Car is still powerless. Also this kind alarm appears in VAG-COM:
1 Fault Found:
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
Have you any ideas what is wrong in my car? I am really thankfull if you can help me.
