I just fitted a V2 to my W216 CL500, it works great but I don't see answers to the below questions anywhere. 1. I work away from home, car will be in a car park for 3 weeks at a time, any issues with power drainage? (Do I need to switch it off during this time period) 2. The "speed limiter adjustment" function, once i decide on my desired height and get the suspension/tyres etc set up for this, does this function have any purpose? 3. I've set my desired height for now, car sits overnight, will it just stay the way I've set it once I jump in in the morning? Thanks, C.
