Recaro seat handles!! Both S3s I have owned I have had to repair them!!! Just did mine today on the new S3 It's an easy fix and if you do need to buy a new seat lever, it's only a fiver from the stealers.
alarm siran batterys
I think all the alarm stuff is located in the boot behind your subwoofer.Where is this battery located,is it built into the siren,as my one does not work.
There is also a controller switch for your alarm and this should be located on the inside of the driver door pilar and you have to have to push it until the red light comes on and then after shut the door and lock your car the red lights next to the door lock things should start flashing and that is your alarm activated.
