Hi all so I’ve had a problem with my car. It’s an Audi 2004 A3 pd engine I left my car for some time as my wife had a baby. It was fine when I parked it up. when I tried to start it again it was dead so I jumped the car and a fault came in it was the maf sensor. move replaced the maf sensor and the fault it still there. I have checked the voltage to the old maf sensor and it’s at 5 volts, when I start the car the maf stays at 1 volt and won’t move even when u Rev the car. the new maf sensor has a 5 volt input and it has 40 mili volts and moves ? Have I brought the wrong maf sensor? also the power at Hugh revs over 2000rpm is really low especially when on a motorway it’s lack of power is very noticeable and sometimes goes into limo mode. I can hear my turbo kicking in a whining when I drive also im thinking there is a few problems maf sensor fault stuck egr valve leak in a pipe ( was fine when I left it tho) actuator not working properly. many help would be greatly appreciated or someone with the same fault.
