No "Lights on?" on E34 1988
Hello,
My 525 E34 year 1988 does not show "Lights on?" warning when I leave it with lights on and open driver's door.
Does anyone know was it an option for year 1988 and which module/part is responsible for this?
I think (but I am not really sure) I saw this warning on my car a few times, so it might be a case that something is not working there.
thank you for ideas,
G.V.
That is a possible symptom of bad capcitors...
When the electrolytic capacitors inside the cluster fail due to age and heat, it can cause messages to fail to appear, as well as other anomolies. See http://www.e34.net

But diid you replace ALL capacitors? Or...
Or did you replace only the four large ones shown on bmwe34.net? Mine had 12 electrolytic caps, and I replaced them all. My "Lights On" message did not appear before completion of the project.

I have found some wiring diagrams of CCM (Check Control Module), and I am going to check if it gets informed about drivers door open and lights being on. Hope this will give me some clues :)
