Help needed.
2007 L322 TDV8 3.6ltr vogue. Uk.
3 weeks ago blew o/s air bag, changed complete leg...no issues, today have just changed n/s complete leg after that blew last week. Problems..soon as I turn key on..... suspension fault 30mph. Loads of faults on icarsoft..

Have you tried clearing them and seeing if any come back?

Bartdon56 · Aug 9, 2023

Yes I have several times, even disconnected the battery for around 30mins. I just don't understand changing the complete leg has given me all these issues, when I changed the right leg....nothing, worked all ok.

It may need calibration. What readings do you get from the height sensors?

Can you get into the 4x4 info screen? may show something

Bartdon56 · Aug 9, 2023

Correct me if I'm wrong but as soon as I turn key to on position it comes up with suspension fault 30mph, no air in system as drained when left airbag burst, changed leg(complete) no air build up.

If the suspension is showing a fault it will need clearing with diags before the compressor will run.

I'll try again tomorrow as I'm off to work(nights)

Thanks all, but will have to catch up later as I'm off to work (nights). If anyone else can add for me to try please add and I'll catch up later on.
Thanks all for you help so far.

Update from yesterday.
Managed to get rid of error codes except 1. RDUM which is 1 error message. No matter how many times I try to erase, it pings up
suspension fault max speed 30mph. Have attached some info.

Got this from a google search "The driver utility module is another name for the companion camera" (venture cam) so not suspension related.

Looking at that picture it shows the front low and the rear high, is that how the car is sitting or is it level?

Also does the icarsoft do suspension calibration?

Sure the height sensors are fitted right way round?

When I fitted one of mine the wrong way it went high not low.

maybe the tracks are dirty then, plugs aint seated correctly, maybe harness both sides is iffy. Strange how both sides been got at and both sensors throwing codes

That's the confusing bit as there aren't any fault codes. And as you say both sides are low. I think it was my Disco 2 that needed recalibrating after I disconnected the height sensor with the battery still connected, maybe the L322 is the same.

Hes got c1872 and 3 for left and right sensor mechanisms. All the other ones are confusing, has he cleared and re scanned it?

Wouldn't surprise me if l322 was even more of a finicky bastard, there's about 3 battery disconnect procedures in the workshop manual ffs

Ah yes in the codes at the start of the thread.
