Left rear lights warning

[akiiraja96]

Hi there,

I'm having some issues with my w204.

All bulbs left rear warning flashing on dash however all bulbs are working fine. Left indicator blinking fast on dash but normally on light.

Please see attached. Could this be a fuse?

Last time the same thing happened several months ago I just taped the wiring where the wire leads to, because it was cracking.

Any advice appreciated.

Thanks

204 rear lights are know to have issues with the ground (earth) wires becoming damaged due to overheating.

Look for signs of overheating in the light unit, black scorching or melted plastic.

Same issue on my c209 clk... I would not have believed it but it was solved by replacing all bulbs with the same brand. The fault diagnosis circuit must be extremely sensitive to for example bulbs with ever so slightly different ohms readings.

Had similar problems with CLK, bulb on way out, discoloured. still worked
Spray with electrical contact cleaner and a new bub.

A fuse cannot cause this. A fuse is there to protect a circuit from passing to much current.
