My trusty 1995 A4 auto saloon is currently immobile The engine starts with no problem but depressing the brake pedal doesn't release the gear lever as it should. Other wierdness - the rev counter is now dead and the dashboard warning lights all come on - oil, temperature, handbrake and low fuel. So far as I can tell the other electrics - lights, wipers, indicators, even the Cobra alarm work as they should. Clearly this is an electrical fault but can anybody provide any pointers to where I should start looking? Could it be a relay? Or is the fault deep in the ECU?

TIA
