The DME that I have in my car is a replacement from an E34, 520, 2L, M50 engine. The BMW hardware number on it is 1703808. I am assuming that the original DME would have had a different number. Does anyone know what this number is?
Am i correct in saying that any DME that manages an M50 2L engine would be OK for my car, as long as I swap the chip from my existing DME to the new one?
I need to get another DME because I suspect that the circuit board has been damaged by water and is showing a software fault on my Carsoft Diagnotic kit. The fault code is: DME40_FE.DXT
Any help or advice will be very much appreciated
