Anyone have a problem with their windows? Sometimes when I put them up, they roll back down automatically. Has 200 miles and its already giving me a problem.

Both of my R230 SLs have done that. Just hold the switch up for an extra second or two.

They have to be reset. There is a procedure to do this. Call MB to confirm but I think you put them down and then up and hold button for 5 seconds.

Press and hold the window down button till the window goes down.
Continue holding it down for two seconds.

Then press and hold the window up button till the window goes all
the way up. Continue holding it up for two seconds.

Do this to both the driver and passanger windows, and it will re
calibrate the window regulators.

Just did the reset for the windows and it worked. Hopefully it wont come back. Thanks

Supposedly you might need to do the reset anytime there is a complete system power failure (when your battery runs down or is replaced, for example).

It's really not a big deal if you have to do that procedure again, is it?

yeah that happened to me too. thanks for telling me how to fix it. It was the first time it happened to me about a week ago ( 1 day after they was a huge rainstorm). Lucky me.

Its a common issue on these cars and need to be reset. After that it works fine. Happen to me once and so far so good.

Ive done this soft reset but it came back like 3-4 times. Maybe the dealer has some kind of a hard reset.

I have a 2000 E320 with this same problem. All windows go down and sun roof opens. Is it common also on that car?

I have done this reset on all my mb's 2000+ and it works
everytime.
