    What do you advise to do?

    Replace the sensor with new one.

    Hey guys, I just replaced burnt transistor but now I have 01318 16-00 Signal outside specifications two lines of same fault on 2002 audi a4 b6 2.5 v6 tdi. Does this mean I killed the board while repairing? I can't find the answer to this nowhere on the internet. Someone asked here on page 50-ish and got no response. Also, when removing the ECU I noticed that part of the isolation on solenoid wires was gone and they might've shorted out or was this caused by the bad transistor? Also, when connecting the plug to the pump while on ignition it makes this fast clicking sound for a second or so. Is this normal?

    Hi, trying to help a colleague with the repair of the VP44 injection pump computer, having some knowledge and equipment in the electronics, following the documentation, I replaced the transistor with a LR2905 that I fixed with the Arctic Silver thermal conductor. The computer was mounted on the pump, the car started relatively easy, stopped after 5 minutes. He did not want to start. Taking the pump calculator checked, the transistor LR2905 burnt as well as the pin 2 (common with S transistor) and the PCB, array / interrupted. Please, if anyone knows what the cause is and possibly the solution. Thank you!
