Hi all Just wondering if it’s possible to re-calibrate the adaptive dynamics on a 2016 Range Rover vogue se sdv8 with my gap iid tool
Got no faults showing up but the suspension and handling is shocking with every bump/pothole etc being felt Last night I lay in bed looking up at the stars in the sky and I thought to myself, where,s the f**king ceiling!!

Switching off DSC makes the shocks firmer so you might like to do a test to see if there is any improvement.

GAP added CVD calibration for the L322 but I don't know if its available for the L405. I've re-calibrated mine a couple of times which made quite an improvement but the shocks are pretty much worn-out so only a temporary measure.

have you checked the tyre pressures, maybe lower them? ... - .- -.

That was the first thing done Stan 31psi in front and 34 psi in back and has made no difference  Last night I lay in bed looking up at the stars in the sky and I thought to myself, where,s the f**king ceiling!!

Will try that today and have a look through the menu on my gap tool
Will get in touch with pat at gap if nothing showing Last night I lay in bed looking up at the stars in the sky and I thought to myself, where,s the f**king ceiling!!

some good info here,

Switched the DSC off today and has had a significent improvement in the ride quality
Ive travelled approx 50 miles today over the same roads I do normally
The car now absorbs the potholes and bad road surfaces a lot better
The biggest improvment ive noticed is the steering ! I was constantly correcting the steering beforehand which seemed to pull slightly to the left when hitting rutts in the road and pothole etc and is near enough perfect now
For some reason the throttle response is also a lot smoother (placebo effect maybe)

So obviously there is a problem with the DSC and all pointing to the link below that stan kindly supplied to me

Range Rover L405 Suspension Fault.
Vehicle range 2013-2017.
TB issued 27.July 2018. LTB00557V10
VIN 000001-380216

The hard part is now going to be convincing the dealer that there is a problem as ive reported an issue with the suspension twice now and head technician seems to think its ok  Last night I lay in bed looking up at the stars in the sky and I thought to myself, where,s the f**king ceiling!!

DSC won't be the cause, only that the CVD module is programmed to stiffen the shocks while DSC is off, presumably so that the vehicle would be more controllable by the driver in the event of sudden swerving. With the improvement that you have experienced and in the absence of the knocking caused by the valve block referred to in the linked thread, I expect that the shocks are not functioning properly, possibly due to their seals worn.

My L322 with 115K kms had totally worn-out the rear CVDs to the point where no amount of re-calibration made them perform reasonably and the front, whilst worn, still provide acceptable damping for normal driving but barely provide adequate control on cross-country sand-hills. None of my CVDs have leaked oil.

Some after-market shock re-manufacturers think that CVDs never wear out, only that the air-springs fail. CVDs still have the normal seals and valves that wear with use in the same manner as conventional shocks.
