I have now invested in a IID tool (very excited) so I will test and confirm if disabling in the ccf allows the rest of the car to run normally with the shocks disconnected.

did you ever get to the bottom of this problem ?
and did disabling in the ccf make any 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!!

Hi Aljo,

I did make some progress with this in that when I received my IID tool I reprogrammed the CCF to tell the car that adaptive suspension wasn't fitted and then unplugged the dampers to make sure that all the systems would still work.

I can confirm everything worked and even with the dampers and control module unplugged there was no adaptive dynamics warning and no codes stored.

Some time has passed since then with no more updates as my life got turned upside down and cars became less than a priority.

However the Range Rover passed its MOT on Saturday with no advisories so I decided to take the plunge and order standard non adaptive shocks front and rear in an attempt to convert my 2010 TDV8 from a horse drawn cart into a comfortable cruiser.

I will update once everything is fitted (assuming it all fits!)

Did you notice any difference in ride after disabling adaptive dynamics? The ride should have been noticeably firmer but if not then the system wasn't working as it should. Once disabled the shocks are always at maximum firmness and therefore either something such as an accelerometer is providing false information making the system think that the vehicle is always cornering or similar effect for which the shocks are made firmer or the shocks are totally worn out, providing no resistance even at full firmness causing every little bump to be transmitted to the body through the air-springs instead of being absorbed by the shocks. However if the shocks are worn-out then the vehicle would also be very floaty.

Great to read that you have made progress πŸ‘
Be interesting to see how it works out with the new non cvd shockers
The ride in my vehicle is shocking πŸ˜‚ not a comfortable ride at all with passengers noticing it too
It’s still under warranty and will give the dealers a chance to sort it out when it’s in for service shortly
But I won’t hold my breath πŸ˜‚πŸ˜‚πŸ˜‚πŸ˜‚ 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!!

Yes I did Graeme,

It went from bloody awful to downright undriveable.

I've driven 3 other cars with adaptive dynamic suspension and although they rode slightly better than my own
it is still my opinion the CVD system is unfit for purpose and shouldn't have been fitted to a 'luxury' 4x4.

No matter now as the order has been placed for standard TDV8 dampers.

Nice to hear from somebody else that thinks this suspension system is pants.

Everyone else I've spoken to describes it as riding on a magic carpet... it really isn't when compared with non CVD equipped 06-09 TDV8s.

Fingers crossed this solves the problem otherwise its getting sold.

Which shockers did you go for ?
I may well go down the same route if nothing is sorted 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!!

I've gone for a pair of dunlop shocks for the front and
Bilstein for the rear.

Sadly oem front shocks are just a bit more than
I'm willing to pay on a whim so hopefully the dunlops
Will be OK.

Total cost Inc sundries (replacement bolts etc)
Β£750 odd from LRparts.

I hope that the non-CVD shocks provide the ride that you're requiring. Ride quality is very subjective.

When I decided to replace my D4 with an L322 with CVDs for a hoped-for better ride overall I had a backup plan if the CVDs weren't to my liking. The plan was to super-impose my own extra softening signal operated by a switch with various softness settings for different surfaces. As it transpired the ride was what I had desired until the shocks became too soft from worn seals so I recalibrated them back to about normal until the rears became totally useless so replaced them with Bilstein CVD versions. The fronts are now incapable of my desired damping when towing my 2.5T van that has a heavy tow-ball weight so will be replaced when they become unsatisfactory in normal use. My first IIDtool calibration attempt was done with the vehicle stationary which resulted in very light/soft damping, totally unsuited to my usage so perhaps you could have tried recalibrating them as you would have had nothing to loose. There is no facility to reset to factory calibration settings but the resultant calibration is variable depending on the roughness of the calibrating surface.

Hi Graeme,

I tried my best with it including probably at least
100 recalibrations over different surfaces at different speeds.

Recalibration whilst stationary gave a hard ride on my car.

As you say ride quality is subjective and I am
spoiled by my weekend car (MK2 Granada 2.Cool

I really liked the ride in my old shape Westminster so
hopefully with the new non cvd shocks it will be something closer to
that.

Update time.

New shocks fitted all round yesterday.

Everything came apart easily on my car with the help of a Sealey 400nm 240v impact gun. (2010 with 130k miles)

No trouble with any of the shock bolts. The job took 6 hours from start to finish including replacing rear discs and pads.

Standard TDV8 shocks fit just fine but you will need the matching mass dampers for the front shocks as the CVD ones will not fit.

An IID tool with access to untested CCF options is required to disable continuously variable damping in the CCF so that you do not get an adaptive dynamics fault display.

The result is a more compliant and wallowy ride. Perhaps still a little firm at the front but I think this is to be expected as the shocks are brand new with no miles on them.

All in all I'm happy and I think the result was worth the time and money invested.

Just another quick update to this for anyone who goes down the same route.

I noticed the other day that every time I started the car I was getting 'special programs off' at the bottom of the dash.

Tried to use terrain reponse and it was inoperative with a warning on the dash board.

The fix was to unplug the now unused adaptive damping module in the rear right cubby of the boot.

All features now working without CVD suspension!

Either unplug the module or remove its power fuse will stop it sending unrecognised/unsupported data on the HS canbus.

I have to say the D3 I’m in at the moment with 243k is more comfortable than my 2011 ff with cvd. It feels like the cvd tense up too much, they’re harder than my m3 was 1995 4.6 v8, green/tan (long gone)
