Did they ever work?

Have you changed the BSI module?

COM2000 is the switch assembly and the BSI is the computer that powers the rear fogs.

There is a plug and socket on the BSI that carries power to the fogs (among other things).

You can test the BSI and COM2000 with the lexia/diagbox clone tool.


Lexia tool is available on Amazon.co.uk
