G Klasse cruise control problem

My Mercedes G Klasse from is showing a cruise control malfunction The speedometer displays an error and the cruise control is non-functional I've scanned the error memory and it confirms a fault related to the cruise control system Based on my initial diagnostics I suspect a defective cable or plug connection to the actuator Has anyone experienced similar issues with the car electronics specifically in the steering wheel area affecting the cruise control

A Mercedes G Klasse owner experienced a cruise control malfunction, with the speedometer displaying an error. Initial diagnostics suggested a defective cable or plug connection to the actuator. Another individual with a similar issue recommended checking the wiring harness in the steering column for frayed or broken wires. The problem was resolved by cleaning a corroded connector and applying dielectric grease, restoring the cruise control functionality and eliminating the error message.

Sounds familiar I had a similar problem with my G Klasse Is the error message constant or does it come and go Check the wiring harness where it enters the steering column It's like a garden hose that's been bent too much eventually it cracks The wires inside could be frayed or broken

The error message is constant When you had this issue did you have to replace the entire steering wheel module or were you able to repair the wiring directly I'm trying to gauge the scope of the repair before I dig deeper

I didn't have to replace the whole module thankfully But I'm not comfortable with car electronics I took it to a workshop and they were able to fix the wiring I'd suggest you do the same if you're not confident

Thanks for the advice I checked the wiring and found a corroded connector Cleaned it applied some dielectric grease and now the cruise control is working again The error message is gone The whole repair including the connector cleaner and grease cost me 95€ Saved a lot of money Thanks again
