I've just bought a TT with some electrical issues. I'd be grateful for any advice which could help me narrow it down to which modules/wiring are causing issues.
The car has the following problems:
I think that's everything!
Any pointers very gratefully received.

The car has the following problems:
- It was sold to me running fine until a hot start, then it wouldn't start until it had cooled down (no orange lights, engine turns over fine, just doesn't fire). Now it's hard to start, only runs for a little while and the EPC light is on.
- I ran a diagnostic this morning (first scan) and engine temperature/RPM readings looked fine. I cleared error codes. Then a while later the engine died at around 90degC. Would not re-start.
- Re-scanning, the Engine module had disappeared (see second scan).
- Keyfobs don't work, Lock button in car works, unlock doesn't. This morning after pressing the lock button, the EPC light started flashing and there were clicks from under the dashboard in time with the flashing. This seems to tie in with the time the car started to lose the Engine module.
- Fuel flap and boot work fine, windows don't drop on opening doors. Roof doesn't work, air break doesn't work but clicks once in one direction.
- Rear window fell in a few weeks ago in hot weather. I guess it's possible the CCM got wet?
- Clicking from diff with ignition on (this ties in with the Haldex data bus issue).
- Stability light comes on intermittently while driving.
I think that's everything!
Any pointers very gratefully received.
