I know these lovely vehicles are renowned for this! We have the eas software which is showing a problem with the driver rear not getting up to the height of the other rear wheel although it is not showing it losing pressure. It is around 10 - 15 less. When driving she struggles to get to correct height and we have just 'bounced' home. Air bags and potentiometers seem fine no sign of leaks (soapy water test). Any ideas?
