I managed to interrupt the roof closing today, I parked and started to close the roof (SmartTop one-touch) and with brain in neutral, turned the ignition off as the roof started to cycle. Well that b*ll*cked the system and everything stopped. Driver window (RHD) made a couple of judders. I started the car, had to manually close the roof by holding the close tab but the driver window and mini window dropped 1" and wouldn't close however much I tried. I tried window down/hold/window up/hold but it didn't work
When I got home and parked on the drive I Googled R172 Window reset and here is what it gave me. I have highlighted the bit that is important as it worked first time.
To reset (resynchronize) the windows and fix the "one-touch" auto-up/down function on a Mercedes-Benz SLK (R172), you need to reteach the window control modules their upper and lower limits.
Follow these exact steps:
Anyway, it's the "don't use the auto position" bit that seems to be the important instruction. Now I seem to need to reset the SmartTop as its become twitchy.

Follow these exact steps:
- Turn on the ignition: Insert the key and turn it to position 2 (or press the Start/Stop button twice) without starting the engine.
- Lower the window: Press the window switch to the first detent (do not click it down all the way into the "auto" position) and hold it down.
- Hold at the bottom: Once the window is fully open, keep holding the button for an additional 5 to 10 seconds.
- Raise the window: Pull the switch up to the first detent (manual mode) and hold it.
- Hold at the top: Once the window is completely closed, continue holding the switch up for another 5 to 10 seconds.
- Repeat for other windows: If needed, do this for each individual window switch.
