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.
