Carlsson C-Tronic Lowering Module Problem. Please Help.

I recently installed the Carlsson C-Tronic Lowering Module on my 2006 SL600, and I am having a slight problem. Every time the car is in motion, the AirMatic suspension raises the car back up and once I come to a stop, the car lowers back down. This does not seem to be the normal functioning of the lowering module. Has anyone else had a similar problem? If so, could you let me know what I can do to fix it? I have checked the wiring to make sure it is correct and everything seems right to me. Thanks.

Did ever figure out problem? Mine appears to be working except when I park and turn ignition off and lock doors the car cls500 raises to stock height and when I start engine it lowers. My carlsson is v2, I don't know if previous versions are suppose to raise back to stock height when car is parked and locked? Because I thought it was suppose to stay lowered even when parked and only adjust on bumpy roads and speeds over 80mph.

When you park and turn off engine does it raise to stock height? And when you turn on engine does it lower back down?

Try to turn off your ABC using the button and see if that helps

This is just a wild guess, Could you have the wires on backwards ? I am only going from your description and have no expierence with the unit you speak of.
