L322 Air Suspension inactive, No ABS No Hill Descent, Wont calibrate

Tim Gosling · Mar 26, 2021

Good evening all,
I had the air suspension failure pop up. I did the full left, full right to rest the steering range and 5 minutes later another failure.
I ordered another steering sensor and this was changed by my local enthusiast Land Rover garage. They were not able to calibrate the new sensor. They had contacted BMW who built my 2004 TD6 Vogue Range Rover, they had no idea what the problem is.
No diagnostic fault codes..
Its stuck in normal ride height. But no Hill descent No function to change it. On the ride height selector knob the light is permanently on. No ABS, Not sure what I can change to rectify this.
Maybe a module? When I stop driving the car engine off and driver door shut the car self levels on the air suspension. The compressor is good I changed the compression ring in the compressor recently.
Any positive support would be welcome. Its quite an integrated system with so many parts that could cause the system to lock out. Not sure if its a body control module or something else.

Did you change just the compressor piston ring or ring and cylinder as just the ring seams to fail very quick.

Why are you changing steering sensor for a suspension fault?
What diagnostics tool did you/they use?

Hi thanks for the response. I bought a new compressor ring, it pumps the car up ok its better than before

The fact that it would not reset, and looking at posts on the internet I changed the steering sensor as it seemed likely to be the fault as recommended by the Land Rover garage.
They have the full diagnostic Land Rover tools

The car needs to know the steering range and calibrate so that dynamic stability control, ABS, Hill Descent and ride Height are all linked

Looks like ou have the same car as me, except mines LHD.

As you say normal procedure to calibrate steering is full lock left to right, no diagnostics required.
Strange there's no fault codes, have you checked your battery voltage is good?

Tim Gosling · Mar 26, 2021

new battery voltage good but always a weak point should have better voltage stability with all the modern electronics, network systems are too susceptible to voltage changes

Do you know which module actually reads the steering sensor position and where does that send data to?

The land rover garage contacted BMW they had no idea of what the fault could be which i find a bit unbelievable

When Range Rovers goes out of warranty they don't care anymore

unfortunately you are right, volvo dont have the same attitude, you can have a 20 year old volvo and they still treat you like your car is new, also Jaguar dont care once your car is more than 3 years old.

what year is you L322?

I did think when TATA bought The Land Rover Jaguar Group that they might be better with customers, but sadly not, If they created a members ownership club like volvo do there would be discounted parts and service for members and a lot of happy owners and cars still on the road 30 years later proving that the support and engineering is above other car manufacturers

Mines a 2005.
Does yours have the touch screen like this (ignore the front left wheel fault)

backinblack · Mar 26, 2021

I think the issue with RR's is that they are so complicated it's to costly to train ~~mechanics~~ technicians to repair the older models.

This is from the Rave manual

thanks for the information much appreciated i will dig deeper, I will check with the land rover garage if they coded it. Really good advise, thank you
