hi there, i have a 3 door audi a3 1999 1.8t which i recently bought, it only come with 1 two button key fob. problem is the buttons do nothing, i have replace the battery with a 2032 batt. i have tried most re sync combinations with no luck!! when i unlock the car i have to put the key in the ignition to unlock the boot and passenger door else the hazards flash repetedly. I have plugged vcds in to find faults with the convienience module but when i try to open the contoller it states 'no responce from controller' does this car have one? i have fault code of 01134- Alarm horn (H12) 49-00 -no communications... any help would be appeciated thanx.
