Headlights issue

[Joe Fabulous]

Hi, I have a 2019 C300.
Started seeing various errors pop up last week. Indicators, lights, etc. Its got progressively worse today. The lights are actually flicking on and off intermittently.
When I switched the car off at home tonight, the headlights stayed on. I messed about clearing errors and leaving the light switch in different positions to no avail. I was just about to disconnect the battery when the lights finally went off.
The cars booked in for a service a week on Monday, in the mean time is there anything I can check for? fuses, relays etc?

Cheers,
Mike

Hello and welcome,

I’d be checking for water damage in the SAM (Signal Acquisition Module (fancy fuse box))

Checked all of the fuses in all 4 fuse boxes. Have also tested the 3 relays in the engine compartment fuse box. All good.
The plot thickens.
