I am not sure of the RRS.
Some had a remote exhaust on the end of a pipe some didn’t. And that ends the extent of what I know, sorry.

My L322 exhaust is at the pump but then it’s in a safe space.

Thanks again just looking now for a good tool.

There are others but I have no idea what they can do.
But dont buy without asking here as you could be wasting more money for the sake of “it’s cheaper”

As I said Gary will be along to help soon I am sure.

Just looking at the icarsoft lv3.0 just asked the seller if it does air suspension
 
Does it do air suspension
It will read any codes related to it, yes

Not sure on calibration and other features, I haven't played with mine much other than reading injector balances and deleting historical codes

Decent starter tool before going for gap i think

The v3 is better
 
Something fishy about all this. I just need my car fixed so I will buy a diagnostics tool just to see what the he'll I really do need to fix it.

hi mate

indeed ref diagnostics the Autel ap200 ( white ) is a very good basic reader , then the gap iid

gobsmacked they had it for 10 x weeks and still didn’t fix it

if the front doesn’t go up at all it can either be a failed front air valve block , wiring issue , calibration out, air leak etc

on The scanner , go into live settings / suspension, then as u raise the suspension see if the front valve block opens , it will show from zero % to 100%

so as they replaced the compressor did they replace it like for like , ie do u know what was fitted before , the scanner will tell u what software u have and that must match what u have fitted, ie, either a hitachi or AMK

may i plse add an extremely important note , plse ensure u have axle stands underneath at all times

so check ur live data , plse let us know what it is, ie, compressor output pressure , what the front valve block is doing as in opening , plus Vdc to it

with the compressor running see if u can hear any air leaks at the front , or at the reservoir valve block , just remove the compressor lower plastic protection cover

never know they may have crossed the pipe connections so have enclosed a hand drawing along with other images

also need to bubble test around the reservoir valve block and compressor

i suspect the front valve block has failed but need to check first , alas there not that expensive these days , decent one are around £100 , plenty of cheap ones around that won’t last very long , very easy to change

before jacking it up u must disable the suspension , raise it to off road height first , then remove fuse F26 from the engine bays fuse box of positive battery lead , then put axle stands underneath

also check the calibration and ensure the height sensor arms are attached and not broken as if the front valve block is opening along with Vdc supply the calibration might be out

the way u do it , measure from the centre of the wheel to the bottom of the wheel arch liner ,

fronts 466 mm
rear 485mm

at the end of the day it’s honestly not a complicated system, just need to ensure u go through it step by step, taking it a chunk at a time

so first checking ur live data and any fault codes that come up

hope the images also help u , plse let us know how u get on as plenty of us here to help

OP, your post is timely as I've been genning up on L320 suspension and have been watching some very good videos which may help you diagnose your current problem





and here from Christian and Vera with their D3. Christian is an excellent engineer and know the D3/L320 system very well



 
What happened immediately before the car went into "Drag mode" ??

I wonder if the front & rear lines from the Reservoir valve block are the wrong way round ? Either that or there's internal leaks in the valve block ?
