Hoping someone can help with some odd electrical issues I’m encountering with my 03 S.
Yesterday I noticed that my MFSW radio controls weren’t working, shortly afterwards the sunroof stuck halfway closed. Managed to get the roof closed manually, but on the drive home I noticed the instrument lights were off, as were the heater controls and blower.

All of the following are non-functional:

• MSFW volume/radio controls
• Sunroof
• Instrument lights
• AC/Heater controls & blower.

I’ve checked all fuses, and everything is intact. Unfortunately my electrical skills (and the ability to read the Bentley manual) are fast hitting their limits
Anyone have ideas about what to investigate next ?

 

seems it was caused by the Ice>Link board. I suspect it was shorting out the K-BUS. Removed it, and all seems to be working.
