How to replace MPM [mini power module]?
 

Long story short, a LOT of snow came a few weeks ago and sat on my trunk lid for a while and it melted into water. Of course you can know what happened next, my MPM fried and my screen would glitch in and out. If I simply buy another (and get the same exact model MPM for my vehicle-specific so No programming, car will do itself) and plug in play should my screen come back on? Please help, my car is a 2005 530i.

Also, it don't look as if the wires in the harness connected to my burnt MPM are burnt so may be no need for harness replacement but I can do it anyways if have to. I just do not want to have to install a brand new head unit. My SOS light is on as well so I may believe it just could be an MPM issue rather than just the screen which I hope as a lot cheaper to replace.

it should, gotta try pluggin it in first

no coding required for MPM, they are plug and play. good luck.

Mpm cause no start? Mine is burnt also, 2007 530i
 

I have same car. Having lots of difficulty with new wires not matching colors. Wish I hadn't cut them
