Darn i wrote a massive write up and the session timmed out on me
Anyways to sum it up.
I had a read though the 3 series compact electrical schematics and came across something which would be worth while checking.
here is the read up -
http://wedophones.com/Manuals/BMW/19...g%20Manual.pdf 1. Check pin 2 on the instrument cluster to see if its supplying any power at all when the park light is switched on.
Questions:
1. When you engage the park light does the interior lights dim? Does the window switch light up? Does the Clock Dim?
2. Dimmer... Are you able to adjust the brightness of the light via the dimmer?
I wouldn't think it to be a grounding issue because if it was it would cause problems with the gauges as well as they are commonly grounded or most of it at least.
