Year of Manufacture *: 1997
Engine Size and Code *: 1.9 AFN
( Optional ) Scanner Used: VAG COM
( Optional) Fault Codes: 00519
Got this in with low power, read fault code 00519 map sensor short to plus. I have tested and load tested all 4 wires on MAP to ecu and bypassed them, I have a brown wire on pin 1 off MAP sensor which is good earth with engine off but with engine running i lose the earth, is this correct?
I have replaced the MAP sensor with a genuine part.
On live data i get the boost pressure up to 2500 bar before code triggers?
I have smoke tested all air pipes and vacuum pipe, tested boost pressure solenoid and check turbo wastegate for seizing.
It seems like faulty ECU any advice?
