Hey guys,
So i recently bought a 2007 L322 3.6L V8, with a few faults, all of which i felt comfortable enough with solving.
The one that got me was the suspension fault.
Initial research indicated that the front left height sensor often fails due to dirt ingress, so i started there, replacing both front sensors.
It didnt solve the problem, so being a clever d*** i replaced both back sensors also.
Still didnt solve the problem, and actually it kicked up a new feature to the fault, which was the suspension deactivating, lowering to the bump stops,
and suggesting a 50k speed limit.

So i called landrover, and they said it would be 3 weeks before they could look at it.
Reading on here, and a few other forums, RSW 4Dcan seemed to be a runner for diagnosing it.
So i bought the software and hardware combo, which was around 200 dollars with delivery, and being impatient, i also ordered a USB OBD adapter on amazon, as it would arrive next day,
which the RSW wifi unit will be a couple of weeks.
The amazon unit took a bit of researching - if anyone needs it here is the link for the unit

You also need to install a specific driver "CH341SER"

So plugging this in i had a front left sensor fault and 0x5A07 C1A07 Cross articulation
So here is what i did on my way to solving it:

>Looked at Live data suspension heights, and noticed that the values were all over the place.
On experimenting i found that they operate on a scale from 0-255, and then pass 255 back to zero.
If they are up around 210+ at normal height, they will pass 255 in off road height, which i figure would confuse things.
I manually adjusted the sensor brackets to get them within a reasonable tolerance, and settled them around the 178 mark at normal height.
The back sensors bracket is only attached with 1 bolt, so its easy enough to adjust.
The front uses 2 screws, so its more difficult, but the bit of tolerance in the fit is enough to get them around right.

>activate tight tolerance mode

>Calibrated heights on each corner measuring from the center of the wheel to the wheel arch.

I got it pretty bang on level, and took her for a spin.
Bang, suspension fault once again, and down to bumps.

I went through this process several times, until today, i tried something new, which if im honest i didnt think would work.
I had a pair of new cross articulation valves in my cart, ready to pay the 300ish GBP for them, and said ill give it one last try with a new approach.

So here is the method that worked for me:

>Deflated EAS completely, bags, reservoir, the works.
>Re-inflated system.
>Enter tight tollerance mode
>Calibrated heights to get the wheels level on the nav screen rather than measuring.
>went out and measured, all within a couple of mm of each other.

Took it out and did about 50 miles, motorway, back roads, roundabouts, no faults, no bumps.
Then i raised up to off road, dropped to access, and back to normal, and when for another 10 miles (Just to be sure that re leveling wouldnt kick it back)
and all good.

The one thing i will be doing is installing a new compressor, i had a pressure sensor fault, replaced the sensor and its fine, but i get the vehicle is lifting slowly warning from time to time,
so i guess the comp is on the way out in the long run. (or short)

But that's my story. what really helped me was a thread on here https://landroverforums.com/forum/lr...n-92905/page4/
which i noticed that the OP, while he switched diagnostics, it was really the advice from the rep that he shared in the post that helped him more so than the system.
His issues were practically identical to mine.

Hope this helps the next guy with this problem!

 

Thanks for posting such a thorough write up. I also have RSW for my P38. I have a Nanocom as well but so far (4 1/2 years in) RSW has done everything I’ve needed on the P38. Nano has been needed on my Disco though.

 

Nice one! I cant fault RSW so far anyway, i think you just need a combo of understanding what your looking at along with the data it spits back at you.
The live data was helpful, and always happy to support another Landy enthusiast, so its win win :-)

 

Finally broke down and got a IIGAP tool for my 2010 LR4 - suspension is original and I suspect it is the compressor.

the code I got is U300-53

- does that confirm or validate anything as far as anyone knows here?

 

From what ive read that looks like you have a software issue on Your EAS,
would be worth re-flashing the software and seeing if that clears it.
Make sure you flash with the correct software for the compressor you have!
