Dynamic Seat Control Gremlins

While driving this weekend I lost air in both the driver and passenger seats. I looked down at the "Dynamic" controls and the red light was off on both seats. I pushed the button but nada. I pulled over, turned off the car and let it sit for a few minutes. I restarted (keyless) and still no go on the seats. I then restarted using the key and the seats came back to life. This happened twice this weekend. Now, it seems like my side bolsters are not coming on as strong in the turns. I went through the command screen and they're still set on "strong." Any ideas?

I don't think it's because I'm getting used to it because I noted a distinct difference right after I had the problems this weekend.

Yes, you can use the steering wheel commands. Start with the menu buttons "far left" until you get to the "Settings" reading on the instrument cluster. Use the up/down arrows next to the menu buttons until you get to the "dynamic seat" controls. Then you use the +/- buttons to change from weak to strong. Pretty easy.

Perform electrical test 12 volts power is ok
Perform leak test - Right front seat for code (9251 leak at right cushion for lateral support)

916685 Remove and replace left seat control module.
916690 Remove and replace right seat control module.

So, I don't speak Mercedes-Tech-a-neese but it looks like they replaced 2 vacuum valves and both seat control modules. This was done 4/24/06 and I haven't had a problem since.

Good luck
