Hi just sharing an upgrade project I undertook in August last year.
Active scan suspension option is not available on 1.5 diesel engine or with a manual gearbox variant so I was curious if I could retrofit
This option was retrofitted to my DS7 Prestige with success!
The system is a variable damping (shock absorber system) managed by an ecu (CSS) using 3 acceleration sensors, 4 vehicle height sensors, 4 variable damping shock absorbers and a multifunction windscreen camera.
There are 3 modes standard, sport which makes the ride harder. Comfort mode uses addition data from the windscreen camera which scans the road ahead and can help smooth out any variations in the road surface by adjusting the voltage to each shock absorber independently.
Hope this might help anyone crazy enough to do the same
