3series 0 Report post Posted September 21, 2008 (edited) Not that I have a clue what I'm on about when it comes to electrical systems but .... could it be a conflict between the 528 chip on the front of the instrument cluster and the new 735i engine management system. We swapped a few 320i clusters aroudn a few weeks back to see if we could fix a faulty cluster and sure enough, facelift did not like pre-facelift (varying ECU's).
