:(Hi All my A4 tdi is weak on power, if i unplug the map sensor the power is nearly as good as it use to be, I have replaced the map sensor with a used unit but the fault is still their.

Is there a simple way of testing the map sensor ?, if the sensor is good would this mean the ecu is not processing the information correctly and making the engine run incorrectly ?

previous to this i have replaced the mass air flow meter with a brand new unit.

Any help would be appreciated :wiggle:
