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.
