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
