2015 535I GT - Integrated Supply Module No Start after changing

[mbarchard]

I had problems with my BMW starting in the cold weather. Engine would crank, but not start. I took it into the BMW shop and they said the Integrated Supply Module was at fault. Car has been starting and running fine for several weeks since, but I ordered the part online and installed it tonight. After install the car would not start. I quickly changed-it out for the old ISM but again now the car will still not start.

I am wondering if there is some kind of re-set required?

Help?

Thanks,
Mike

The module probably needs to be coded, most modules these days are not plug and play

The integrated supply module is nothing more than a power distribution block. It's not a coded part. Plug and play. If it started before and not now, you either did something wrong, or it's a coincidence that something else failed at the exact same time. You need to scan for any fault codes with a proper BMW scan tool (not a generic P-code reader).
