Hi, I have a mk3 octavia vrs TDI and I've had an engine light on my dash and the warranty company have changed an auxillary water pump and the light is still on the dash, once they looked again, there were multiple codes for various engine component shorting to ground or open circuit. They have told me it seems to be an electrical fault and that it isn't covered by warranty. I'm going to have a look myself, just wondering if anyone has had a similar issue or know where i can get hold of some wiring diagrams. Thanks
