Got an X reg Ibiza Cupra. Started having problems a couple of months ago when the coolant fans wouldn't cut in. Thought it was sorted by garage, but the fault returned a couple of weeks ago when i was in traffic. Took it back to the garage and it seemed to be working OK. They said it was something to do with the fuse bracket on the top of the battery (the small fuse at the end had overheated and melted some of the plastic), which they cleaned up. Since then, the temp and fuel gauges have stopped working - well the needles move about a millimetre when the ignition is switched on. In addition the red and orange LEDS light up briefly when the ignition is switched on but go out after a couple of seconds. Had an auto electrician look at it who says the sender units are working fine and the gauges are OK as well. He said it's something in between not communicating. I've changed the bracket on top of the battery and cleaned up the two earth bolts at the back of the engine compartment just below the windscreen. Anyone got any ideas what might be causing these faults (fans and gauges) or where I can fine a wiring diagram for the car?
