E46 Light control module, what else does it control?

[martin mrt]

Reason I ask is, I have bought a 2002 E46 330d touring as a non runner with a burnt out LCM along with the wiring plug that plugs into it, It's an ex police car that had the sunroof patched up for some unknown reason, this over time has cracked and allowed water past and dripped onto the switch/module burning it out.

The seller assured me the car ran fine until this happened and afterwards it wouldn't start so it was just left until he could find time to repair it, this however hasn't happened due to a busy work schedule,

So would the light control module being fried have something to do with the car not running? I have bought it cheap and hope to fix it to use as a daily/work hack, a replacement module is included in the sale but hasn't been fitted

I think its linked into the cluster which is linked to the ecu. You will need the exact module to replace Xenon/Non Xenon etc.

That makes sense, I had done some slight research and I found that the LCM module stores the mileage I believe, im at a loss as to what else it does other than the obvious controlling of lights, it would be exceptionally good if a small bit of wiring repair, and recoding of the replacement module gets it running again
