For those cars with EML:
The EML light should come on when engine is started in ignition position 2 for about 2-3 seconds and then go off. This is a kind of test for the 2 bulbs inside the motherboard of the cluster. One bulb acts as a kind of resistor for the other, to speak in my no-electric expert words.
People have paid hundreds or thousands of $ to repair shops because they replaced unneccessarily MOTRONICS, EML and other parts of the car, as the car was in limp mode and they could not solve the problem.
Limp mode, also known as failsafe mode, limits throttle openings etc and runs off a preprogrammed setting, limits rpm and speed as well...
Vmax after 2 minutes approx.50 kmh in 3rd gear, at max. 1500 RPM, no ability to climp uphill and so on.
A member of 7er.com has just made a write-up with pics. Of course it is in German, but the pics are most important to understand.
Main points I just translate in brief into English, I will omit the general info on how to remove the cluster from the dash, and other points known to all of you which are regular visitors on this board.
Pin 16-17, the only connected soldering points of the "white" plug are to be connected to the "upper contacts" of the 2 EML lights.
Option: Pin 12 of the "brown" plug to be connected (soldered) with the "lower contacts" of the EML lights.
As connector he used hot glue.
Leave cable long enough to assemble the cluster again.
Notes:
No guarantee for correct translation. It is your car when you repair it.
Description is based on a cluster from a 750iL from 05/1989.
If you are not able to see the pics in the link to the German board, you might have to register first. Easily done, no cost involved, and they have a very good repair page, done and maintained mainly by Erich = shogun ;-)
