Looking into flooding. 4" water in battery compartment and power brake area. Since I can't redo this wonderful German design, where are all the drains located that prevent filling up these areas? I will tak eout battery tomorrow. Are there drains in other locations?

Cabin air filter seems to be vulnerable to water entry. No cover. Water running down windshield is supposed to be deflected/routed where?

Thanks

Seriously need some help. As above. installed replacement central lock controller I cleared all codes and ran again. Cleaned up. I pulled battery while cleaning out drains (source of flooding).

Hooked battery back up and thought everything would reboot. Matched keys etc.

Sun roof will not respond. Half way down window will not respond. Radio comes on no sound, remote trunk latch does not work
Interior lights (reading etc) do not work. Runs, remotes work, turn flasher/emergency flasher work

I have some switches unplugged: Memory seats, folding mirror switch a few other things. Figure that would not effect anything.

I need some guidance as to what steps to follow to get all these items on line again.

Thanks.

Hi tultalk,
A full Autoscan is the place to start.

Yes, post a new autoscan as we don't know what new comfort module you had installed and if any DTC-s are stored according to the functions not working.

This is scan after I replaced Central Locking module (4B0 962 258M) with one from eBay and cleared all the old DTC codes from it. 2 scans to make sure.

Temp repair using wire nut on cleaned previously corroded splice V 37.

No DTC except this

But radio works fine both am and fm

Strange, my previous scan showed no fault here:
