Right, i managed to find a second hand ecu on ebay with exactly the same part numbers. I plugged it in when it arrived today but seem to be having the same problems as before - dsg lights flashing, esp and tyre pressure lights on(amber) and car turns over but wont fire. Scan with vag com and get 01314 engine controle module communications error and 18258 powertrain databus P1850 - 000 - Missing Message from ECU.
Now im thinking its not my ecu at fault, could it be the can itself? Im not that clued up with this system so scratching my head now
Could it even be the battery?
Help please....................
