NEED HELP! '00 TT w/ severe electrical issues after disconnected battery
I have a 2000 Audi TT. Over the weekend I did my best to completely degrease the engine bay.... while I was in there I noticed a plug with four wires attached (by the driver side headlight) that was not connected to anything.. so I took out the battery to have more room and get a closer look. The battery stayed out of the car overnight, as I wanted to clean up the engine bay more the next day and had more access with the battery out in that certain area.
1.) I degreased and hosed down the engine bay
2.) Battery was disconnected from the car overnight
TWO days after the battery was put back in and driving the car, the car suddenly develops electrical issues.
Issues:
1.) passenger headlight flickers
2.) both windows are extremely slow at going up and down
3.) aftermarket radio no longer works, but flickers lights on its face
4.) odometer needle is inaccurate, will stick at 60mph no matter the speed
5.) temp gauge reads 3/4 when car has been sitting for hours
6.) A/C doesnt work
7.) When A/C is "on", headlights wont stay on, dash lights go off
8.) Car needs a jump start if its been turned off.
etc...
What can I do to fix this? Is this all because of the main fuse? Did I blow something? I don't know where to start, and am looking for help!
Any help or advice is appreciated!!! I'd like more intel onto what happened to cause all these problems and what I need to do to fix it. Thanks!

Either you didn't tighten the battery connection or the terminals have corrosion and needs cleaning. Since this is a battery related issue go back and check everything. You might also want to check the alternator since it sounds as though it might not be charging your battery.

Electrical issues
You could have possibly gotten water in connectors that were not totaly sealed.
I would probably check the battery connection first. Clean battery terminals and cables.
Look for electrical connections, seperate the connectors, spray some WD40 on the connectors and reconnect. Do this for all the connectors you can find and get too.
Good luck
