power module

I have tried to search and found no definitive answer. Does anyone know if the power module in the trunk has to be coded to the car? I got some water in there after doing some body work and it seems to have shorted out the module. I have all kinds of lights going on in the cluster and I believe it is due to the power module not supplying the other modules correct voltage. Please help.

Yes it has to be coded to the car. I traded member Paper for one that he may sell you. Contact him.

I replaced mine and it didn't need to be coded.

2 different answers any other input? And I I do need to code anyone know how to? I have inpa and BMW scan 2.01 working on laptop.

You have to Code your vin to the power module.

Maybe it's because I bought a brand new one, but I checked the screen in INPA that shows all the modules with the VIN assigned, and it didn't show an error.

I believe you have to code the IVM, which is sometimes referred to as a power module, but that's under the hood.

I thought the ivm is a swap and the power module in the trunk needs your vin coded.

I'll hook up my computer and check again tonight, but I'm sure I didn't code it. It shows the yyyyyyy in the VIN column with no errors. In the past, if a module needed to be coded, it would show an error on that screen.

Ordered a used one on ebay for $100 hope it works. If not I will report back.

I put a new one in my 06 750li and didn't code it, no problems after 2 years...
