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
