A Klasse turn signal fault

My 2021 Mercedes A Klasse hybrid is throwing a fit. Keeps saying there's a fault in the lighting, and the turn signal lamp error is burning my retinas in the speedometer. Plugged in my reader, and it's got a stored error about the turn indicator. Suspect it's a dodgy cable or plug. Has anyone seen this?

Yep, same thing happened to my A Klasse. Electrical fault with the turn signal. Was driving me nuts.

Was it actually the wiring or the flasher relay itself? Where did they find the actual electrical fault?

Honestly, didn't dig too deep. Just took it in. They said it was a loose connection, some kind of known issue. Saved myself the headache.

Sounds like the best bet to avoid tearing my hair out. Will book it in. Hopefully, it is just the connection because these things can be a real pain.
