Mercedes M Klasse Diesel Steering Column Issue

I've encountered similar issues with electronic steering on Mercedes vehicles Since you suspect a cable or plug connection have you checked the wiring harness and connectors leading to the steering column adjustment motor Pay close attention to any signs of corrosion or damage Also does the error code specify which component is failing

Thanks for the quick reply The error code doesn't pinpoint a specific component just a general fault in the adjustment circuit I've given the wiring a once-over but should I be looking for anything in particular beyond obvious corrosion Is there a common point of failure I might be missing

If the error is generic and you've checked for obvious corrosion it's possible the adjustment motor itself is faulty However before condemning it I'd advise a deeper dive into the wiring with a multimeter to rule out any broken wires within the harness Considering the age of the vehicle it might be time to let a workshop take a look

Appreciate the insight I did a more thorough inspection of the harness as you suggested and found a broken wire A quick solder and heat shrink later and it's working perfectly again Thanks for pointing me in the right direction
