So, I have a 2003 L322 where the front left air suspension strut developed a small leak.

The car has gone into “Air Susp. Inactive”, but I’ve since replaced the faulty strut. Can’t reset it using the recommended “touch the terminals together” aka “disconnect the battery” trick because it still remembers.

I have a bluetooth ODB2 scanner, but I don’t see the relevant error message on it to clear.

Is there any way to reset the car and get it to try inflate the suspension again without an expensive iID Gap tool?

I believe you just need to “clear the fault code”, or reset the code. Any specialist should be able to do it, but will obviously charge.

An OBD reader just reads, no writing so I’m sure you could get one that clear codes too. I’m no expert on the readers so no real help I’m afraid.

I know the computer sees that as a “hard fault” so won’t clear on its own.

I think any generic fault clearing device can do it. Happy to be corrected.

Have you a mate with a device that clears codes? Don’t need anything fancy like writing to CCF etc…

My device can see one error code, something unrelated (evap sensor disconnected)
Lets me clear that, but not the suspension code.

This has worked for my 2006 car, check that the height sensors are fitted correctly, and that they have not flipped the other way around, start the car and let it run for a few minutes, carry out the old steering angle sensor reset trick.... full left lock / hold 3-4 seconds / go to centre / hold / go to full right lock hold / back to centre. Wait a minute then see if the suspension will operate. Usually works for me, sometimes after doing this twice, I have had this message a few times but never needed my reader to reset the fault. 2006 year may be different ?

Hello,

Powerful UK have a clip on YouTube showing a reset turning lock to lock.

Try the BMW INPA. You need a cable from EBay say, and the software should come with it. Lap top required to plug in the USB.

Turning lock to lock apparently doesn’t work on the earlier l322 models ?


I’ve tried and the message doesn’t go away.

I don’t hear the air pump even trying when the car starts. Should it?
Hard to know if I’ve fixed the issue without it clearing this error.

You really need to get a dedicated code reader and keep it in the car at all times. For most including me the IIDtool is to expensive however there are much cheaper options albeit with slightly less functionality. I would recommend investing in an Autel AP200 Bluetooth dongle that works with a smartphone. You should be able to get one for around A$85. This will work on any Land Rover vehicle and is not locked to one specific vehicle, it can do most thing you will ever need, it cannot write / reprogram modules however I understand it is able to calibrate the suspension heights. 2007 TDV8 VSE

Haha, yes, car doors are closed. Error message just pops up straight away, no pump sound.

So far I’ve only replaced the single air strut that had damage and dropped height. All other corners of the car are at height.

Is there going to be much of an improvement on the Autel AP200 vs the Ancel BD unit I already have?
I decided against the Autel model because it doesn’t work without an internet connection and where I’ve been travelling across the outback didn’t have phone reception, let alone reliable internet.

If the steering wheel, lock to lock doesn’t clear the error, is there anything else that could be causing the fault message to come back so quickly?

Autel AP200 does not need internet once set up. The software does update regularly which is free and like any other diagnostic tool will require an internet connection for the update. I have one, its excellent for the cost. As You see I am in Perth and regularly travel remotly solo and would not leave home without the Autel.
I just googled Ancel DB, thats just a simple OBD2 scanner. It is not a dedicated all systems scanner 2007 TDV8 VSE

The system is locked out due to the hard error. Nothing will run and nothing will come back on till you clear the error. No good listening for the compressor, door open or closed…. You need to clear the error and then go from there.

All good now. The Autel AP200 unit has more detail in the error messages available.
Found a "32 CAN bus Fault". Cleared that error and the new air struts re-inflated immediately and have been working fine since.

Setting up the Autel unit was a bit of a pain though. No signal coverage/data in the garage where I was working on the car, it wanted internet to setup the registration and download the setup files, but it also wanted to be connected to the unit via Bluetooth during this process.

"Decode VIN" fails, but manually selecting the model and year works fine.

Nice one. Hopefully good for a few more years now.
