Ride height behaviour
Posted: Tue Dec 10, 2019 5:09 pm
As a follow on to my suspension firmness issue (resolved with new NSR RH sensor), i still find occasionally that parking up after a journey, the RH can be noticeably higher than when i started i off.
I thought CATS via ASM would change the RH dynamically, and hence, once i had come to a stop, the RH should revert to standard?
Or, does it take time for this to happen? I’m aware that the ECU or ASM wakes up at various points once double locked and adjusts heights accordingly.
Eg today - prior to setting off on a 10 minute trip, RH are perfect on all 4 corners (a 2 finger gap between wheel arch and top of the tyre). When i arrive at the garage and stop (ignition off), all 4 corners are raised so that i can now fit 3 fingers between tyre and wheel arch.
The forecourt at SSG Automotive is quite uneven for 20 ft or so, so wondering if this caused the RH to rise, however i was expecting it to be back to normal when i parked an switched off.
Is this normal?
