I’ve tried doing a height calibration on my 2006 RRS HSE multiple times and it always gives an error that there is more than 3mm difference. I did notice that the difference in the front fixed after a second attempt but not the rears. Here’s a screen shot of differences. Also when I measure the height it’s pretty much even across. I have no faults, do I just need to keep trying until it corrects it self, or maybe bad rear sensors. I was also thinking what if the previous owner coded/program different settings for the suspension with idd tool, would that not allow me to do a height calibration. Another thing to mention is that before doing the height calibration the vechile would always go to extended mode when trying to enter access mode. Now I could enter access mode after a second attempt of going into extended mode. I’d really love to complete a height calibration.
