Despite having my LCM 'repaired', it turns out it was still going faulty, but only after using the stereo daily for around a week.


Anyway, I bought another LCM (fortunately from the same year 4.8iS), fitted and coded this to my VIN, set the mileage to 0, and have been using this for a few weeks now without my instrument cluster crashing. Hooray!


I'm guessing my original LCM was water damaged at some point. The guy who refurbished it said it looked like it had evidence of water having gotten to it.
