I have Audi 1.9 tdi 130 bhp 2001. Every time when car is left for a couple hours after driving, or over night, it won`t open from remote key. But once you open and go for a short drive, remote key works. I have changed the battery in it, but it did not help. Also the middle button on the key does nothing, the boot won`t open. Does any one know, what is wrong?
