Suspension issue

Ok thanks, can I reset system with Snapon tool? Would that work?

after i read better seems that the software update refers only to later modells than your's so might not be the case

Reset/clearing codes after you have noted them then see which 1s come back, if any is always a good place to start.

Still needs recalibration though no way out of it with the new sensors

J

Also note from the fault code posted it seems possible to maybe mix up the lines, As you have been in and replaced the rear valve block then that maybe a quick easy check you have it plumbed in correctly.

Ok thanks do you have a map to
Check airlines

I will dig out what I have but its only L322 stuff so could be different so wouldnt want to lead you wrong. The basic system is the same but not sure its all in the same places.

All my stuff shows Hitach not AMK which I am sure you have, so different

See what you can figure out from this doc

Thanks seen on pipe some
White tags any idea what the white ones are

Are they blue with white tags.
As I have seen that in my docs as the same line but diff is front or back, think.

It should be in that last doc posted as it was that doc I was reading for the L322.

See if that snap-on tool can read live data to check the system pressure cos as the pressure sensor is a possible suspect it should be visible on the pressure reading maybe you are lucky to be that cos it's easy to replace

Plus 1 ^^^

fingers crossed is the same on the d4

plse also note suspension re calibration must be done in normal ride height , that’s in between access and off road height

u then need to measure from the bottom of the wheel arch liners and centre of the wheel in mm , plse see what they are

indeed with regards to the code Reader , should be able to tell u what the exhaust Vdc, height sensors , ABS , are all reading in Vdc

not familiar with the snap on unit as use a gap iid or Autel mx808 , fingers crossed it should allow u to see into multiple modules

as a side note many modules req a 5Vdc input and a ground , but again code reader should allow u to see these readings

plse let us know how u get on as there’s plenty of us here to assist if u get stuck, i learnt a lot after having to virtually rebuild my D3 suspension system and think the only difference between them is the connector locations

hope that also helps
