So yesterday the problem started on my 2011 JSW. The amber "light bulb icon" on the dash turned on, and a slew of messages such as "Check your left brake light, " Check your rear license plate light," etc. scrolled through.
All lights are stock and still original bulbs. I did a visual check, and a bunch of lights were out. It's a different combinations of lights on either sides (on one side: driving light, the rear brake light, etc and on the other side: turn signal, headlight, etc.. including license plate and third brake light in the middle).
(FWIW, Navigation is also returning CD Changer fault but I don't think it's related).
EDIT: found http://wiki.ross-tech.com/wiki/index.php/00979 and http://wiki.ross-tech.com/wiki/index.php/01499 and http://wiki.ross-tech.com/wiki/index.php/02394; either bad bulb (not the case), bad wiring (why intermittent without the car moved?), or bad module coding (why intermittent?), or do an output test (?). Still don't know where to look yet.

- All bulbs are ok; all filaments are intact (and they would turn on again intermittently)
- Fuses are all good.
- VCDS scan returned 11 Central Electronic faults 0010: 00979, 00985, 01497, etc. Here's the full scan at pastebin.com.
- After sunset and the temp has dropped a bit, tried the lights and everything turned on!
- This morning, I waited for the sun to cook the car on the driveway, and the issues returned.
