Steering wheel adjuster not working..

I am new to Bimmerfest and thought of no better place to bring my questions. I currently have a 2004 530i and the steering wheel adjuster does not work at all. There are no sounds when I toggle the steering wheel adjuster and nothing moves. Does anyone know what this might be?

Thank you in advance.

Fuse? When did it work last?

Check fuses, then pull the switch module and check connections, then... maybe replace the module (switch module is fairly cheap). After that... well, after that you might start looking at the connection at the SZL or the adjustment motors (although the motors last as I wouldn't expect them all to die at the same time).

Thanks Pimio, I'll check it soon. By chance what is the switch module? Is that the little toggle to control the steering wheel adjustment? The steering wheel heating button next to that toggle still works. And what is the SZL? Sorry about so many questions, I'm pretty new to BMW components.

The switch module is a one-piece unit that contains both the steering wheel adjuster as well as the steering wheel heat button (see this Link from realoem.com. I had to replace one as part of a steering wheel retrofit, and it was something like $80 CAD, so it will be much less down there. You can't just replace the steering wheel adjustment part of the unit, the whole thing needs to be replaced. There are a couple of connectors which could be the issue and worth checking.

The SZL is the switch control module for your steering wheel - it's what translates all of the various signals from the buttons/paddles, etc and sends them to the rest of the car. It has a number of other bits and pieces like the steering angle sensors, etc. It's the "switch unit steering column" on this diagram. To be fair, I'm not sure it has any connection to the steering wheel adjustments, but it's involved with just about everything else to do with the steering wheel - I had to replace it to add the heating funtion to my ///M wheel.

As for fuses, a quick check online turned up an E60 fuse diagram (for a UK diesel, but may be the same) which indicates a separate fuse for "Steering Column Adjustment" - fuse 13 in that case. That's where I would start...

Had that happen on my wife's 530. They repaired under warranty.

I don't remember exactly. I think it was a bad board. If I remember I will try to look it up.

So update on what I found out, or the indy found out. He stated that the SZM was dead and it caused the steering control to malfunction. A cost of about 900$ in parts and labor. Does that sound right? Everything else works properly, steering wheel heating, seat adjusters, seat warming, dsc button, dtc control and so on. Only the steering wheel will not adjust.

Does anyone know anything about the SZM? I'm curious if I can just find it at some junk yard.

Can u post a pic of what the szm looks like and location. Nice job fixing ur problem. Perfect example of the value this site and its members is. A savings of 900.00 bucks is huge...

the szm is the module that is directly under your DVD drive..
with your parking sensor button and your dtc. you must take off the panel with your hazard button
then your air contioning button panel and should slide out with that.
