That really is p*** poor, especially on a brand that's considered to be premium/prestige
..... Happy to report they confirmed the manufacture fault and paid all costs, and I drove away within the day with the lights fixed and the car cleaned inside and out!
im having exactly same problem.. did you manage to resolve the issue.. let me know asap plz !!Rear lights acting silly
I've had A problem with my rear lights!
Please help as this is driving me mad
The front & mirror indicators flash as normal yet the instrument cluster flashes rapidly, when this happens the rear indicators don't work or reverse lights.
This also plays havoc with my headlight switch causing my front fog lights to go off, The fuel gauge also plays up at this point and the rear demister fails to work.
I checked the rear light clusters and the bulbs had started to melt at contact point because of overheating so I replaced all the bulbs and cleaned the contacts on the cluster. However the wiring and connectors seem to be in tact.
The bulbs get hot and the rear SAM unit located close to the drivers side rear light in the boot has several relays that are quite hot also.
The lights do work as normal for a short while when engine switched off for a while but then play up again at random.
My W204 has done some miles but that shouldn't be an issue
Any help will be appreciated thanks
Had the same problem soldered a brown wire to negative section of rear light cluster and connected it directly to nearby earth (body of car) so bypassing faulty plug connection.Works fine next to no cost.
Update to the above fault:
I've now driven about 400 miles after the fix (as above) to Ambleside and back and no more problems whereas I was having a Rear "Rear N/S indicator fail" every 10 or 20 miles previously
Thanks sid300sl
cheers
Hi JimHi Abzmercowner
Sounds awfully like an earth fault to me? I'd be inclined to try connecting the earth track on the bulb assembly directly to a suitable earth point (one of the nuts that hold the unit in place would be suitable) .
Just to try it if you've got three hands ( a helper ) unclip the bulb holder assembly and hold a piece of wire, one end on the on the earth track ( just see where the end pin that the brown wire is connected to) , the other end on something like the boot catch and get someone to switch the lights on. If they now work, solder a wire from that track to a screw earth as described earlier in this thread.
Worth a try
