Mercedes SLC clutch switch issue

My 2017 Mercedes SLC with a gasoline engine is acting up I've got an error stored in memory related to the clutch pedal switch The gear selection display in the speedometer is showing dashes cruise control is dead and sometimes the engine won't even start I suspect it's an electrical fault Has anyone dealt with this kind of weirdness before Is it likely the clutch switch itself or could it be something else causing these symptoms Anyone got any ideas before I potentially shell out 95€ for a new switch

Sounds familiar I had something similar happen with my SLC Gear selector going nuts cruise control dead Clutch switch eh Did you check the wiring harness Maybe wiggle the connector a bit Sometimes it's just a bad connection Did you ever have problems with starting the engine before

Yeah I gave the connector a wiggle but no dice I haven't checked the harness thoroughly though What exactly went wrong with yours Was it definitely the clutch switch or something else causing similar symptoms And what did you do to fix it

Yep for me it was the clutch switch The symptoms you describe are spot on I tried cleaning the contacts but it was toast Honestly at that point I just bit the bullet and took it to a workshop It was easier than chasing wires for days and potentially making things worse you know If you don't have the right tools it's just not worth it Good luck

Thanks for the info I appreciate you sharing your experience It does sound like I'm on the right track so I'll probably just go ahead and replace the switch I took it to the workshop and they found the electrical fault in the clutch switch and replaced it Everything seems to be working fine now
