Wenn die EML Lampe staendig anbleibt, kann ein Fehler im 'Motherboard' des Kombiinstrumentes sein.
Hier dazu der Kommentar von Hairywithit:
There are 4 plugs between the EML and the EML lamps
X1602 on the EML
to
X21 round plug in front of water valves
to
X34 under dash next to hood release
to
X502 on the instrument cluster
The power for the lamps passes thru X17 so you can pull X502 and check the response. If the lamps go out then the short is in the wiring. If not, the short is in the cluster. You should be able to pull the cluster forward and remove X502 without having to remove the steering wheel.
