Alarm kept randomly going of in night and key fob would switch off then a few months later Key fob wouldn't unlock car, alarm went off but I could start car with key and drive.
Few weeks later car wouldn't turn over, jump started no worries, didn't drive for a few days and wouldn't start. Jump started all okay.
Same again a few days later, wouldn't jump start, so took battery off to charge, then the car would start for a second as immobiliser is on flashing with alarm.
I've brought new battery, new Audi key fob batteries, Sprayed WD40 in ignition, no joy. Can turn over stays started for a bit longer, immobiliser and alarm on cuts out.
HELP!!!
