'01 TT Relay / Fuse Block Problem? Wiring Schematic?

First post - thanks in advance!

Quick note - this is a US model 2001 Audi TT Roadster with original equipment.

Major problem is the seat heaters, the air conditioning/windshield defroster units and the outside temperature gauge are all non-functioning. They all went out together with no known problem. Got in the car, flicked the defrost and it just didn't work. Tested the seat heaters and other items to see what else had stopped working. There is a factory radio issue that derived on the same day listed below. I've checked the fuses in the dash panel and all is great.

I then checked the 2 relays under the hood (408 & 100 or 110 - can't remember at the moment) just in front of the firewall on the driver's side. They tested fine with an electrical tester. Taking the fuse block out of the dash reveals MANY more relays (8 that I can see) behind the dash but in places where they cannot be reached without removing the dashboard. I did also check the fuses and grounds in the junction box mounted to the top of the battery with no problems.

I guess the question is, has anyone had any similar problems like this or does anyone know where to find an '01 TT wiring schematic. Just trying to save a few bucks before I take it to Audi. The closest dealership is over an hour away and I just don't have the time to take it to them. There is a guy here that works on foreign cars and re-built my engine last year after the timing belt took a nose-dive. But I hope to use him as a last resort just because of his hourly rate.

Any help would be greatly appreciated!

Secondary oddity is that the radio can normally be turned on with the car off but kills out when the door is opened - a great feature I liked. When all this other stuff stopped working, now the radio comes on at random while no one is in the car and sets off the alarm. I keep having to remember to push the center button on the radio OFF everytime I exit the car and then turn it back on when I start the car back up.

Thank for any help!
