    hi all,new to this so thanks in advance for any help.

    my problem is as follows-
    sometimes my a3(2005) wont start(immobilizer) and i have to disconnect battery lead for a second to reset system and hey presto starts no problem.it can work fine for a few weeks and then act up every 3th or 4th time i try start car.
    it has become annoying now and need it sorted as its a pain having to lift bonnet on main street or as today a petrol station.

    also my outdoor temperature guage reads -14 even when its 20degrees outside ??????
    anybody ever had this problem or any advice?? thanks

    regards eoin

    I wouldnt be disconnecting batteries in a petrol station!!

    Could it be a poor terminal connection if that solves it each time?
