Yes I just wanted to try replacing it with an old one to see if this specific error goes away. Then I'll send off mine for repair.

I checked all the yards, none of X5s have these modules lol. They must be in demand!
Interestingly I removed a module from E39 2000 pump, and it seems to fit on X5 pump lol!
No idea if it would actually work, if they're Interchangeable or what's the difference
