Lamp failure warning indication E280 2000

[jons086]

When the engine is running and the side lights are switched on the 'Lamp Failure' warning light comes up on the dash - but I dont have a light out!!
If I switch the engine off (and reset the warning indication) I can switch ALL the lights on (with the ignition on but engine not running) and the warning light does not come on until I start the engine? This problem is driving me nuts! Any ideas?

Is it possible to 'link out' or disable the warning indicator so that it does not illuminate ever again! ?

Thanks

Ian

Lamp out

If you have an incorrect wattage lamp ie 100w headlamp bulb, that will do it,the system normally measures; side,main,dipped and tail lamps,faulty brake lamp will show up when you press brake pedal.

Have you checked to see if the barke lights work correctly?

Had an ongoing problem with rear light bulbs burning out for years on a 124 300TE with the subsequent lamp out warning light. Turned out to be that wrong wattage bulbs had been used before I bought the car and I just kept changing them with the same spec without realising it (bulbs would used to last about a year).
Best to check that all bulbs fitted are the correct wattage by referring to the spec in the user manual.
Hope this helps!

I had a problem on the 210. Warning light coming on with the brakes but all seemed ok. Replaced the bulbs anyway and ok for a few days then back to normal again. Fiddled with them and ok, but started warning again soon after. Then I noticed that one brake light was a bit brighter than the other even though the bulbs were identical. Turned out to be oxidisation on the contacts. Cleaned up both sides with a bit of wire wool and eased the contacts back up to make a better connection at the same time. Been fine since.

Replace the rear lamp bulb holders, they are cheap and are a known source of trouble.

Turn the lights on without touching brake pedal, if indicator shows all ok.press the brake pedal if the indicator lights up you have a faulty brake lamp/bulb
