Hi all,
I have a 2015 i3 with Rex.
If it turns out my EME is bad, I understand I could fit a secondhand replacement swapping the coms board.
That way no programming is required, providing the fault is seen in the swapped main unit.
Investigation finds a big change in late 2016 when some charging electronics was altered.
Also the Rex and Bev models have different part numbers for the EME.
I have seen that higher rated batteries are being swapped in with no mention of a EME swap, just a reprogram.
So it would appear the battery size doesn’t matter.
Part number checks finds EME with Rex up to late 2016 are a match. However is it due to the pre-programming done by BMW, which swapping the coms board would resolve.
I think I read that a non-Rex could be used in this situation as no internal differences, but I can’t refine that link.
So 2 questions
1. What EME’s are an option to use to swap in my coms board ?
2. Is it feasible to remove the EME by lowing engine rather than complete removal.
Merry Christmas all
