Hello,
I’m new to the forum it looks interesting.
I have a RRS 2008 TDV8 having some difficulties with the ride height sensors. The car is in the garage to get 2 new front sensors fitted, original Land Rover parts, fitted to the front of the vehicle but started showing suspension fault straight away and the car dropped to the ground (low). A second set of sensors were fitted and the same problem occurred so I have had to revert back to the original sensors which are intermittently showing faults and the car is laying down lower on one side than the other (front only), on top of this when I manually drop or raise the suspension height the suspension starts raising and goes into a “suspension in extended mode” red flashing symbol and shows the wheels jumping around on the screen. When at normal height in fault mode the car is much lower at the front than the back. Hence the reason why I seen the flashing red indicator on the screen for the front wheels and ordered new parts.

The mechanic contacted a Land Rover specialist to get some advice when they said they wanted the vehicle in after a month waiting list. I’m now stuck and need the car for work etc. I still have the 2 new sensors and would greatly appreciate any suggestion you may have to solve the problem.

A new compressor was also fitted recently which was a direct replacement hitachi so I’m guessing no need for a software update? Should it needs a software update for registering the new sensors? Seems that some treads suggest yes but some suggest no but I also came across a recall for sensors! I’m just confused now! Thanks in advamce for your help. Much appreciated.

After new sensors are fitted the suspension needs calibration.

Bit hard to believe 2 sensors failed at the same time

Andy,
Thanks for the reply.
One sensor failed initially (front driver)so I replaced that with a used sensor and it sat a little lower so I drove it anyway after which the sensor on the passenger side started showing a fault when the suspension was in use so I ordered 2 new sensors from Land Rover. This is when the problem started as above.

How is the suspension calibrated exactly? Is it a software basic settings change or is it done mechanically? Thanks again

Not sure this will work on a RRS, but on other LR vehicles I have had with EAS, I disconnect the
battery before removing the sensors. Saves having to recalibrate them.

Is the Delphi auto diagnostics system any good for land rovers? Would any of you recommend a system to properly acces the cars systems? Thanks

We tend to use an IID to cal the suspension on here. £400

You get your tape measure out, measure between wheel arch lip and wheel center.
Do some calcs and tap some numbers into your smart phone

Or take it back to the garage, tell them they’ve not completed the work, get a courtesy car and leave them to fix it. Robin

It’s a mates garage. He specialises in Mercedes so he has all the gear for those. I fitted one sensor back this eve and it cleared the faults temporarily so next step is to calibrate them and clear faults again.

Andy- thanks for the info. Would I better with a IID tool or IID tool BT? I’m guessing you’ve confidence in these so I’ll take the recommendation and use it with a smart phone.

Thanks again. Appreciate all the help and suggestions

Yes many of us on here use the IID.

BT means Bluetooth to work with a smart phone. SO yes Bluetooth is the one you want.


I can't guarantee the calibration will fix your problem, but the IID is a very useful tool, which will come in handy for other things. Read the fault codes on the car, program keys, activate options, update software etc

^^^^^ No way Jesus, that could have been very nasty! Steve.

Yep. Luckily it was the uphill wheel on a slope - the downhill side would have chopped off my arm. I'm a skinny bloke without any muscle to crush so no crush injuries but a very blue arm!

The neighbour who first came to help had nightmares about what would have had happened if I had put my head through the gap.

All I wanted the fire brigade to do was jump out their wagon with a jack and lift the car off me. Instead, they formed a huddle and performed a risk assessment for about five minutes. Just as the airbag lifted the car off my arm, one of the pneumatic couplings came away and dropped it back.

Lessons learned: expect the worst; the 'transport' position of the air suspension is verylow; for a supposedly intelligent person, I have a lot of Frank Spencer traits.

Lucky one there with the arm! 😳

I took the RRS to another garage for a last run before buying the IID tool as previously said it may not sort my issue and I’m planning on changing it which wouldn’t make any sense with the tool licked to the car.

The garage changed some settings and tried their best with their Bosch computer system what they have now accomplished is successfully calibrating the suspension “normal height” on the “off road height” setting so basically the jeep sits good on off road height and but when I hit the 25mph mark it dings and drops again thinking it’s too high. Pain in the ass!!!

Any further suggestions?
I need to leave the jeep with the boys for a day or 2 so they can have a proper go at it but I find it very strange that it’s calibrated in off road height?? There was not mention of off road/normal/access height settings it just showed the settings. We calibrated it and she reset herself but it was off road. I also made sure the setting in the on board screen was on normal height setting
Constantly showing red fault signal light.
One more thing - when I lower to access height (doesn’t move much) it automatically goes to off road height and raises the jeep.

Again. Thanks for your help. Adrian

Hmm - this is a long shot - and I'm no expert - but there is a facility for the car, when it senses an obstruction under the car, to go into super high, just to get over the obstruction. It couldn't be this aspect playing up could it? Your comment "one more thing..." made me think of it  Robin
