Driver's door electrics - locking/windows/mirror dead

[kevinb6]

Hi,

On my '02 A4 B6 1.6 petrol the driver's door electrics wend dead last week - nothing working - central lock (via fob and inside switch), windows (both sides) and mirrors adjustment. Also interior light on all the time and dash did not show door was open.

Found earth wire (brown) broken where loom goes into A pillar. Removed loom from door and soldered in a patch wire and did two other on way out. I did a nice job I must say, heatshrink and new tape Checked continuity with meter including flexing it while checking.

Put it back in car. Interior light now goes off and dash sees door is open. Passenger window now works but only from it's own switch. Everything else still dead.

Used contact cleaner on both sides of A pillar connector and plugged it in and out many times and get positive click of tab.

Checked all fuses related to doors and comfort module.

Could the broken earth wire have damaged the comfort module (the one in the floor I believe), or the control unit in the door?

Any ideas please?

Would I need to reset an error in the ODB?

Thanks, Kevin

UPDATE

Double checked wiring with a meter from cabin side of A pillar connector to end of loom in door. Disconnected battery. Locking is now working via key fob, but everything else still dead. Checked the comfort control module under carpet it's bone dry and cannot see any issues.

I'm thinking it might be worth a try getting a new (used) motor module in the door (8E2 959 802 B), pic below.

Would I need t get that programmed to match the key, or is that controled from the CCM?
