Xenon and park light fail
Hi,

I have a W164 from year 2006. Got this error message after diagnostic. Is the failure in front SAM or in the actual light?

Right side everything works fine. Also High beam and turn signal left side works fine.

Any other symptoms/fault codes no matter how unrelated they may appear? A short to ground usually poor wiring shorting against the chassis/body somewhere. Front SAM controls all lights front and rear. Swap globes from one side to another as a start? I'd focus on wiring given these cars at 20 years old now.

The headlight wire insulation on this era of Mercedes have a habit of falling apart when they get old.
