ECU damage ?
When I scan for fault codes with VAG-COM the fallowing codes appears:
17563 – Short to B+
17565 manifold pressure sensor G71: supply voltage
First of all I change the G71 G72 4 wire sensor. I check the wires from the sensor to the ECU with Ohm-meter and they are ok, but the errors are still there and cannot be deleted.
In diagnostic mode the N75 Solenoid valve (vacuum) moves, but when I command to move up it move down and when the command is down it moves up, so that is OK J
In a disparate move I change the ECU with an older version without immobilizer, and I have no errors and for 3 or 5 seconds the engine runs well (the N75 Solenoid valve begins to move the arm for vacuum …..) [img]/ubbthreads/images/graemlins/smirk.gif[/img]
This message “manifold pressure sensor G71: supply voltage” it means the ECU not power supply the sensor? If this is true, can I do something? The ECU can be repaired? Or I have to buy one [img]/ubbthreads/images/graemlins/shocked.gif[/img]

Re: ECU damage ?
have you tried using electrical contact cleaner on the plug that connects to the ecu?
maybe also try using this cleaner on the contacts on the ecu.
