I installed the c tronic model#31001001 for an 06 cls500 w219 as directed in the manual with lowest setting 30mm front and 25mm rear. Everything appears to be working great but I noticed when I turn engine off the car raises back to stock height. When I turn on ignition car lowers to set height it is suppose to. I thought when car is turned off it is suppose to sit low at all times? Sometimes the car will stay in low height when car engine off and parked. Is this normal? Is this an older model and the newer ones sit low when engine shut off? I have the pins open/on up for 30mm front/25mm rear as directed and for car type cls united states pin 9 closed/off down and pins 10-12 open/on up. And I have pins 7 and 8 closed off. Please any advice greatly appreciated.

 

Anybody? I know some of you have Carlsson installed.

 

C'mon anybody?

 

sounds like some kind of computer problem. the fact that sometimes it stays lowered when the car is off and sometimes it returns to OEM makes no sense at all. what is the power wire for the unit tapped to? if that wire does not have power, then the module will shut off and the car will return to OEM height. I can adjust my module even when the car is completely off, but if the module itself lost power the car would return to OEM height. I do not have a carlsson module though, I have Programa, who is the manufacturer of the RennTech v2 modules.
