Blower unit: 11 65 1 277 183. Suggest you attach 12v to the fan connector and see if it works before buying a new one.

Aux Fan: Yes it should connect to that connector. I beleive it provides 12v at run only.

Interior lights: Could be the interior light relay (974 5-pin). It's pricey, about $80, but you can jump 2 connectors to see if it's the relay or wiring problems. I have to check which connectors I jumped to troubleshoot.

Big relay: It could be the power window relay. It provides power when the driver door is open. You can check that by removing it and seeing if the windows work.

Exterior temp sensor: Should be on the front spoiler beside the left fog light.

I'm starting the process of fixing and removing the hacks that i've found on this car.

Anyone have an ETM that I could borrow or pay to copy?

Some questions:

* Anyone know the Bosch number for the afterrun fan? This looks suspicously like the injector cooling fan in my Audi 200 tqa, (which is back in CT so I can't check the part number). I need to get some deep sockets so I can remove my fan. It does not work. Wiring checks out OK.

* The aux air valve was replaced by some mechanical gizmo with a cable!!! New valve on the way. I assume this should connect to the loose connector on the injector harness, near injector 3.

* Any idea why someone would disconnect the cold start injector, and connect 2 wires to it that go under the dash? I thought it was part of the mess of alarm wires which I was pulling out, so I cut the wires before I bothered to find out what they were connected to.

* My interior lights do not work, none, including the rear reading lights. Any ideas where something might be disconnected? Think this is part of the alarm botchup?

* There is a big relay, #205, under the dash, thats hot to touch. Any ideas what it is, and whether it needs to be replaced?

* Where is the exterior temp sensor? Mine reads -22C. Probably disconnected or dead.

* In the drivers side speaker hole, besides the Seimens ECU, there is another VDO ecu. Does this belong under the dash cover or in this hole? What is it - cruise control?

Thanks in advance. Samir.
