I am having the following suspension symptoms on my 2003 L322 4.4 V8 petrol. I have owned the car 3 years. Any ideas?
  • Twice this month I have had the "Max height 30mph" message flash up for a few seconds even though I am in normal middle hieght suspension mode both times driving on twisty roads at between 20 and 30 mph
  • I have noticed over the last year that the front suspension adjusts height upwards when pulling to a stop even though I am in normal middle height mode (I do not beleive this to be due to an air leak as the car does not sink even when left for 2 weeks between driving)
The car drives absoluetely fine otherwise and remains delightful!
 
Thanks. I don't have a code reader is tghere a good one thats not silly money that will read the manufacturer specific suspension faults rather than just the universal OBD readers?

There never is a good cheap diagnostic suite unfortunately.. Unless it's second hand!!!
I'm not sure what system you need for yours, @holidaychicken, @Saint.V8 are two who will know better than me.

It still amazes that people associate the L322 with the word cheap. Although they might be able to buy cheaply, with sites like this around, and easy access to all threads, one would think they would understand by now, that buying is the last cheap thing they will ever associate with it. :rolleyes:

Hey gold, yip and yip.
Cheap +RR...
RR+cheap....
You can't have cheap and grrrreat, In the same sentence I'm afraid.
If your keeping your RR, invest in some good diags for it. You won't regret it and then when you are armed with more info you can get the help needed a little more easy. ;)
 
Thanks everyone for your thoughts. Sorry shouldn't have used the word cheep; perhaps good value for money would be a better term. I certainly don't shirk from spending money on the car! I knew what I was getting into! However I am also careful with my money. What would be more helpful is to be pointed in the right direction with diagnostic gear rather than being told off for not wanting to spend money unnesserally. I have bought full manufacturers diagnostic gear for other cars I have owned when there has been no alternative and will happily do the same again but it would be helpful to know if there is an alternative!

I'm in Coventry BTW

If the suspension works normally and there are no warnings on the dash (other than the one that flashes up and goes again), all the ride heights work OK...then maybe diagnostics may not help because as far as the system is concerned, there is nowt wrong!

The re-adjustment when coming to a stop can just be the system correcting its height as when braking the nose of the car dips, once you come to a stop the system will make an adjustment to ensure the car is sitting correctly level so it pumps the front end up a bit after the pitch forward movement of braking, if it adjusts by a considerable amount, it could be an indicator the front air springs are getting tired....but a movement of half an inch shouldn't be to much for a cause for concern.

As for the warning message flashing up; How good is your battery? and also, it might pay to take a look at the electrical connections to the EAS ECU, due to its location it is susceptible to damp.

Thats really helpful thank you! I had wondered about the adjusting when coming to a stop - what I am experiencing would certainly tie in with what you describe although the movement is nearer an inch than half.
With regard to the warning message my battery is good so i will check the connectors as you recomend!
 
For a Fault COde Reader, iCarsoft is very good, but it doesn't so any calibrations or setting changes....

All Comms is very good for the price and co do various calibrations and setting changes....

IIDTool is very very good, but getting pricey....

Faultmate Extreme is the dogs danglies...but you need to re-mortgage the house for it....

All that being said, as I post above, I don't think diagnostics is required in this instance....

Thank you again! I know I'm going to have to invest in one at some point soon.

Its a Range Rover - you will need one.....

I use the iCarsoft for day to day fault code reading and live data viewing.....it is about £140, but it can't do any setting changes or calibrations....so I use RSW Solutions All Comms for that and is about £220 or so depending on exchange rate from the US.

IIDTool is an immensley capable device and you can get a bluethooth verion that connects to your phone which is pretty awesome.

There are various others like Bearmach's Hawkeye which has good and bad reviews - mostly because it doesn't do EAS calibrations etc.....then there is Britparts Lynx which is quite well thought of, but not much take up of it on here....and of course ther eis the Foxwell stuff which I have no experience of so can't comment, but others do rate it....then the Faultmate Extreme which is basically LR dealer grade and will set you back £1000+

I remember looking at All Comms when I first bought the car three years ago. I was slightly concerned about buying direct from the US so its good to know you have had a good experience. Is there a reason you don't use All Comms all the time. Is it clunky for basic fault reading?
 
It needs to be run on a laptop which means quick fault finding is a matter of getting the laptop out, plugging it all in, making sure the battery is charged etc etc....whereas the iCarsoft ( and the others) is powered from the OBD socket itself, and as such runs without the need for any additional batteries, cables etc....



Now who is this smooth talker????
 
Great video! Looks like the iCarsoft is a great starting point.

Next question: when/why would you need to calibrate the suspension?
 
Thanks again Saint V8! Really helpful information. I have changed the front struts recently and wondered if calibration was needed. Also when I disconnected the battery last year to do some welding (proper repair to the leading edge of the rear wheel arch- both sides), I had to run the car from low to high suspension and back again to clear the "air suspension inopperative" message. When you you started to talk about height calibration I had wondered if either of these bits of work would rendor calibration nesesery. However as i didn't mess with the height sensors in either case, I assume not.

I am investing in an Icar soft but will probably end up buying an All Coms eventually too! Meanwhile I can't find anything amiss with the ECU connectors so it may have been a temporary blip.
