Light Out error?.

[PeteH]

Hi

2009, Rapido On 3L V6 Auto, Sprinter Base. I have a "tail light" error on the dash comes up when I switch the side (and head) lights on. All the lamps check out as working, but the error light remains. I have consulted several Mercedes online "forums". And suggestions range from mismatched lamps, to wiring faults.

So far I have removed and replaced the lamp (standard twin filament 21/5 Pilot and Brake) despite the fact the O/E lamp was not actually faulty. I still have this issue.

It is annoying rather than anything else, as I know I have a full working light set from physically examining the M-H when lit. and I can switch the error off on the steering wheel by cancellation, (it returns next time I fire up).

Any one come across this before?. I suspect it MAY be an earth issue, but finding and cleaning "earthing" points is a long and tedious job. So before I go that route I wondered if anyone had had the issue and a solution.?

Pete

I think this would be my starting point,,, along rear end of chasis N/S should be some earthing points. hope you find the solution.

I have the issue on my Mercedes Rapido, I get a tail light warning and a side marker light warning, although the lights are OK. My solution, such as it is , is to ignore it.

Problem with that is that if a light really does go phut you will not know.

Have you checked your brake lights? Mine did this with an intermittent brake light bulb fault. Replaced brake light bulb. This seems to have fixed it.

Re-Check, this am, shows failed Number plate light Fitting. (Bad Earth). All fed from LH lighting!. I am certain it had been On when I last looked, But????. Repaired the fitting and now OK.

Whilst on this I found 3 of 5 High level brake lights out (tiny little bulbs) When I tried the replace them they broke in the fitting. Have bye passed the Existing lights, with 2 strips of LED`s. Works a treat!.

Thanks guys for input.
