The Distronic cruise control on my 2004 SL55 recently stopped working.

Basically, the car will display a message saying that Distronic is unavailable and it stays that way until I restart the car. The error message only displays after a few minutes of driving but it comes on consistently every time .

I tried cleaning the sensor and the grill thinking there might be some interference but I’ve had no luck. Has anyone else had this issue? I was thinking about ordering a replacement sensor but I figured I’d ask here first.

I had an issue similar and it turned out to be a wheel speed sensor. Check error codes.

I’ll scan my codes later today and I’ll look into it. Thank you for the suggestion.

It ended up being a bad sensor, the one that sits behind the front grill.

I ended up just ordering a replacement sensor from eBay for $75 and now my Distronic cruise control works perfectly again.

Installation was pretty easy. It only took like 15 minutes to replace.

You need to get the replacement sensor aligned, otherwise it could cause a serious accident.
