Steering Wheel Adjustment

All of a sudden, the Up/Down function of my steering wheel does not work. IN/OUT works fine. Tried disabling/enabling the easy exit function with no luck. Anyone experience this and is there a reset that can be done?

Yeah, you should let MB investigate it further, there may be many reasons to be honest. I know a guy who got himself a deal on [commercial plug deleted] was having similar problems, but they were solved pretty fast by them.

When I got my 2013 SL550 home I had to go to the local dealer to get a few parts. My wheel did the same thing as yours. I went to the service department to see how much to repair it. The guy came out to my car, got in, moved the wheel way back, used his left leg to put upward pressure on it and slapped the rim hard with his right hand - It has worked fine ever since. He says users climb out of the car using the rim for assist and lock it up. What really surprised me - NO CHARGE! They have a new customer when I need them because of the way I was treated.

I hardly drive my SL, but recently realized the easy in/out (up/down) function was not working. My service guy checked to see if it was covered under the CPO plan, which it was. However, my curiosity got the best of me. With a little research, I found that the pictured component (worm gear) is what operates the up/down function. I knew the motor was working because I could hear it clicking. I pulled all the happy horse shit out of the way, beginning with the lower dash, black cover (pain in the ass), two screws, all the components attached to it just unclip, OBD plug, & wire harness. Rear cup holder fascia, left side console trim, left side wood trim on dash, the fuse box cover, left side, there is a screw up in there. A few screws drops the knee air bag. No need to unplug the air bag, it will lay there. A this point you'll be looking right at the worm gear. A few allen heads and the worm gear pulls out from the electric motor. The electric motor has an opening that the drive end of the assembly goes into. Very simple, you'll see. I expected to find something broken, but found that the black block that is driven by the worm drive was actually just seated tight against the stop (black arrow in pic). The electric motor does not have enough torque to unseat it. As RussBarnes said, it maybe possible to use leg pressure and maybe hit the steering wheel to jar it loose. To reverse the torque to move that black block off its seat, would really take a lot. Incidentally, when the worm gear is removed, the steering wheel will move up and down by hand. Looking at the two pics, I think you'll get the idea in regards to trying to reverse the torque. I just white lubed everything, put it all back together, all is fine. The picture of the whole assembly is off of Ebay, I did not remove the whole thing, just the worm drive.

Had the same problem plus seat would not go up and down. Moved seat all the way forward and all the way back and problems solved with that reset. Worth a try rather than a trip to dealer

When you say all the way back, is that all the way in or all the way out? What is back?

Thanks

I have the same issue, and I want to try this.

Well gosh darn, moving the steering wheel all the way in and hitting it hard with your right hand fixed the up and down issue. Amazing! Thanks RussBarnes!

This is exactly what I had to do to mine 2 years ago. Been fine ever since

Conflicting stories about all the way back or all the way in. I can just try it both ways. Not clear about where to hit it hard -- where on steering wheel -- top or bottom -- hit it up, down or straight in. Thanks for any clarification. I want to try this
