    Over the past few weeks my alarm has been going off after i have used the remote keypad to lock it, also my rear wiper has stopped working and on the dashboard display keeps saying the boot is open (when it is definatley shut). Due to this my battery went flat over night as the courtesy light stayed on, Mr AA came to jump the car and said it is a common fault with a3's as there is one unit in the boot that operates all of the above. Has anyone else come across these problems as it is driving me nuts.

    This happened to me. I'm in the process of writing up a how to with pictures. I got all the symptoms that you are experiencing apart from the wiper motor failure.

    Basically remove the boot lining x 2 torx bits, the rest is just held on by clips.

    Remove the electrical connection from the lock.

    Remove the lock from memory it was 2 x 13mm bolts and there should be a pool of water in the connection.

    Dry out, i used compressed air(I was at work)

    Obviously this is a short term fix but it saved me having to buy parts.

    PM me if you want the pics emailing or more info

    Thanks for that ive had a look at it myself today and the water pipe at the wiper must have come loose at some point as it was soaking inside. dried it all out and checked all the connections and still no joy so.
