AUDI A4 couple of problems need help/ advice

[sheffieldadz]

I recently bought an Audi A4 1.9 TDI (130) 2001 (51) and have come across a few problems. Thanks

1 the drivers door will not lock or unlock with the remote fob but it will lock and unlock VIA the key

2 the "AIR BAG" light is on on the dash and won't go off

3 the rear passenger door non of the lights come on (footwell, door handle, door lights red and white also the interior roof lights dont come on)

when i press the unlock button all the doors open/lock apart from the drivers door.

the passenger door doesnt have a key hole.

also when i hold the unlock/lock button the windows will go up and down and the indicators will only flash when i unlock the car but not when i lock it.

thanks for your help.
