Hi guys, help needed please.
I'm totally new to the Bmw game, just bought a 520d touring with a few problems.
Rear wiper doesn't work
Rear heater screen doesn't work
Radio reception doesn't work.
Very short range on remote locking.
Rear glass keeps opening when I drive off.
I've been looking through old posts and seems to point me to the diversity thingy or damaged wiring.
Yesterday the central locking from the key stopped all together.
What should I look at first? Or can anyone help please.
Thanks

I replaced the aerial dirversity thingy as the old one was heavily corroded inside.
Made no difference.
Then took the right hand boot loom out and found 4 broken wires, soldered them and now the reception on radio is good, remote central locking now works from a distance.
Rear wiper still doesn't work and the boot glass still keeps opening. Think it's the micro switch

The rear heater cable is in left inner loom with coax and washer pipe. As for both right hand looms, you need pull the cables out from roof speaker and to do a proper repair you need to extend the whole bundle by 5" or else the problem will return. There is sencom youtube video for your reference.
