JMC 0 Posted September 1, 2010 Usual thing when this happens it is either the ECU relay or the Fuel pump relay - replace them both (about £20 from VW). Have a serach on here, comes up quite often. Quote Share this post Link to post Share on other sites
mimjed 0 Posted September 1, 2010 As above very common faults, ignition switch is another one. When mine did this it seemingly turned out to be a bad connection at the ecu. Get the garage to check the power to pin 25, assuming its digifant 1. Open the ecu and check the two small screws inside are still in place and tight, this can cause a bad connection. Failing that take your immobiliser out, mark the cables with masking tape and write on the tape what colour cable it came from. I marked whether it came from top or bottom. Then just recconect with some 2.5mm singles and choccy block. Need to solder if your keeping it off but for testing its fine. Quote Share this post Link to post Share on other sites
