Does the ride height look ok ?? if yes try this .........

Do a hard battery reset ..... remove earth battery lead off battery and cross it over to the positive for 30 seconds or so , this will discharge all capacitors and 'keep alive ' memory functions .

Just taking off a battery lead on modern cars is not a full re boot so that why hard battery reset nessasary nowadays ....... fixes all kinds of issues on Range rovers i can tell you !!

Reconnect battery ....you will have to reset windows and any other learned type functions , put car in dynamic and have a good drive round in it ....vary your speed .... excelerate /de celerate , the ecm should hopefully start to relearn the firmest road map , then try in comfort see if any better .

If this does not fix it i really dont know where to go ???

Would it be possible to "tune" the Suspension computer to send more amps to the struts to be softer?
