A colleague of mine has an A3 (T reg). The alarm seems to go off for no reason, both when he's driving, and when it's locked and parked in the car park. Note, the alarm only sounds - the indicators don't flash. He just took it to the local dealer, who said it would need to be booked in, as the alarm unit seems to be faulty - but they can't accomodate him at the moment. We've looked in the manual for a fuse, to turn the thing off, but can't find anything suitable. Can anyone help? Thanks.
