I think he's hoping you guys will have an answer, from his video yesterday

Sam, having watched your vids including your latest one, can I make a suggestion? Instead of making some gastly spare wheel holder for the rear! It would be far easier to cut the spare wheel well out and fabricate a central well (for the original compressor) weld in a flat floor and mount the spare wheel underneath a la Discovery 3 & 4...

That’s one of the accelerometers that affects the damper ECU. There are three I think and from memory this one is under the spare wheel cover.

To answer your question about the history of my issue similar to yours: it’s always been like this in my ownership. I have no errors on mine.

Watching the bonnet movement in relation to the road does seems as though it’s the front bouncing but as per your notes it feels like it’s the back Question


I forgot to mention this, but one of the first things I did was the replace that rear accelerometer in the spare wheel well with a good used one - to no avail - however it might be worth revisiting. I know there are two more at the front, but they don't seem to be as easy to get to. Any ideas here?

I've not managed to do much more diagnostic work on it unfortunately, as my last couple of weekends have been taken up entirely with filming and editing a new project Laughing

I might do an IID tool data log of a few bits - maybe height sensor voltage, plus damper current. I'll post it here so you guys can take a look. Any other suggestions of what to log?

Thanks all!

Hmm... sounds like a decent idea, I'm just trying to picture if it would work. Wouldn't it be dropping down where the exhaust & back box sit currently? Also, I've always hated how you can see the spare wheel hanging down underneath the RRS / D3/D4 from behind. It probably isn't as much of a hindrance off-road as it looks though.

I don't think the IID can log damper current, it's been discussed on here before IIRC. I'm looking at building something that'll log x,y,z forces and damper current, but just haven't had the time recently.

Ah I see. I can definitely log it using SDD, so that's a bit annoying they haven't implemented that in IID.
Accelerometer forces are definitely in SDD too.

As an aside, is there any way that you know how to check injector balance on the 4.4 TDV8? I have an occasional uneven idle that I'd like to check out on mine.

I'd honestly think this functionality was available on the IID, I mean my old Nanocom can do it for a TD5! Very Happy Very Happy

But... but having done a (very) quick search on here, I found this post which *seems* to imply that the IID can't implement it fully and so SDD is the way to go.

Not sure if this is of any help... anyone else know for sure?

I have watched your vids and commented in the past as i have the same rear end harhsness issue, I really think the subframe busshes must be replaced ... if you think about it your shocks and suspension bushes can be as good as they want to be but the whole rear end they atatch too goes to the rest of the car via those four bushes except for the top of the struts right... (the 4 bushes known to be flogged at higher k's) ... so its just crazy not changing them Embarassed Laughing

I had my car jacked up one side the other day (rear end) and after putting it back down there was a sharp odd sudden movement i cant seem to reproduce..... Scary really and i dont know but i think maybe subframe bushes which ill swap out real soon

Re headlight leveling as an fyi for whoever the L322 doesent have it as its not required because we have self leveling suspension... also the reason the rear of the car lifts first then the front when changing height

Research bmw x5 rear subframe and bushes etc as they are all but the same %100 and youll get loads more info from the web Wink

The L322 definitely has headlight levelling if fitted with xenon’s, that despite also having self levelling suspension.

When the driver’s side rear height sensor rod became detached on my 2002 FF, the Xenon's were pointing at the sky using their self levelling motors.

From the L322 workshop manual:

Headlamp Levelling (Xenon headlamps only)
The automatic headlamp levelling system automatically adjusts the vertical positioning of the headlamps to provide
the optimum headlamp beam position for maximum driving visibility and preventing glare to oncoming drivers.

The system is controlled by an automatic headlamp levelling ECU located at the bottom of the LH 'A' post. The ECU
is connected to and receives information from the Hall effect front and rear height sensors which are also used by the
air suspension system. The ECU also receives a signal from the ABS ECU for vehicle acceleration. The ECU has
diagnostic capabilities and can communicate with TestBook/T4 via the K Bus, the instrument pack and the DS2 Bus.

The levelling system is a fast response system which reacts to changes of vehicle angle when driving. The ECU
receives vehicle speed signals from the ABS ECU and a brake switch signal from the LCM. These two signals are
used to adjust the headlamp position to compensate for changes in vehicle attitude due to acceleration or braking.

Stepper motors, located as part of the headlamp unit, drive a threaded rod which moves the lower edge of the
headlamp forward or backwards to adjust the vertical position of the headlamp beam. The stepper motors are
controlled by the ECU which, using the data from the height sensors, determines the attitude of the vehicle and
compensates for load differences at the rear of the vehicle or changing driving conditions. 1992 RR Classic 3.9 efi Vogue

Embarassed

I was about / meant to say 2010-12 dont as ive never seen mine move apon startup and remember others saying them same thing however i just checked the wiring diagram and it shows motors for bending and leveling... Embarassed

Well thats exciting i honestly thought they never leveled... ill have to sus this out , Take my headlight comments with a grain of salt from now on Rolling Eyes Laughing


Anyway i wonder if Sam has ordered the subfram bushes or not yet ...

Actually (haha) The following taken from the 2010-2012 wm-

Static Headlamp Leveling - Xenon Headlamps
Static vehicle headlamp leveling is performed by the air suspension system and the air suspension control module. The
suspension system constantly monitors the vehicle attitude and adjusts the height of the front and/or rear of the vehicle
accordingly. This maintains the correct vehicle attitude and consequently maintains the correct headlamp beam alignment.
The vehicle leveling system is fully automatic, therefore the lighting control switch does not have a manual leveling rotary
control.

So im going to get to the bottom of this and pull some headlights apart Cool

Static levelling is done by the air suspension but headlamps that turn also level during hard braking and hard acceleration.

So the cause of the hard riding issue may have shown itself today!

A couple of miles into a cruise up the M6 today, the dash flashed up with 'Adaptive Dynamics Fault' and the yellow warning triangle. This is the only time I've ever had a warning light come up, and been happy to see it 😂

Strangely, the ride in the Range Rover was also immediately more comfortable after the warning appeared. I'm guessing that the system disabled any damper stiffening action when the fault was detected - as it did feel noticeably more wallowy in the bends when I got off the motorway.

When I arrived, I plugged in the IID and got an adaptive dynamics code: C1A05-14.
So I've got a replacement height sensor on the way. I also need to check the wiring all the way from the sensor to the AD module. But it's promising to have had a code appear at long last!
