Reading the Sunday Times motoring supplement today it states 'Criminals will either smash a window or jam the vehicles remote signal to prevent the car from locking. Once inside they plug a device - roughly the size of a mobile phone - into the diagnostic port fitted to all modern cars, which connects it to the vehicle's computer. This allows it access to the codes needed to program a blank key fob that is held close to the device. Within 20 seconds crooks are able to lock, unlock and start the car' The models mentioned are A4, A5 and Q5. Does this mean Audi have secured our A3 using a different format? Has anyone had their car stolen using this method?
