Thank you so much but what is so unclear to me is what is that programming really doing. I did it last time ascertaining  4 different heights, corresponding to all 4 wheels, in mm as well, finished the job and, surprise: nothing positive happening but the susspension went down again to it s original height, so low that you can not put your index finger between the fender and the wheel (for both wheels on the rear axle). Due to this halucinating fact I took the process from the begining putting back the original values, which were in place before starting the height adjustment process : 616 mm for the front axel and 618 mm for the rear axel. In real life the real measurements, for my currently 17 inches mounted wheels, were: 574 mm rear left, 584 rear right, 623 both front. I must confess that 3 doors out of four were opened during the process ... oh, and something very important I believe: after that process the EHC module reported an error, which ISTA+ said it was not a real error, but a warning ”transport mode activated”. I deleted the fault and everthing is fine now! Weird isn t it? I will try it again these days! 
I need to clearel understand what is that measurement telling to vehicle: those measured mm are currently the height of the vehicle, so the EHC should command the increment of  that height to a predefined/standard value or those measured values become a standard height, written in an module and the vehicle will do nothing to alter the height and just take them as good? I remember that before starting the process ISTA was attentioning me regarding the Height adjustment process, saying that the process must be initiated only if I replaced the ISM module for instance and some other situations but nothing about changing the air spings on that axle. Thank you so much for your precious help!
