Iv had my third Audi a3 2.0 ti quattro now for about a month, when i got the car it cam with 2 keys and both unlock and lock the car manually and both start the car, one fob has never remotely unlocked/locked and the other did but intermittently, it has now stopped working all together, iv tried every possible route to recoding the keys to the car to no avail. Iv even had it on VCDS with a specialist which cleared a few faults, he re synced the keys via VCDS which made the hazard lights blink when he did each one in the ignition but then both keys wouldn't unlock the car, we then wiped the memory all together of keys on the car and tried again and still nothing, he said that when he's doing it everything he's done means the keys should work but when he looked at the signal in VCDS when a key fob is pressed no value is registering the signal. with the key working sometimes it makes me think the whole central locking system is working but its getting really annoying now unlocking and locking my car manually all the time, Any help would be much appreciated
