Hello,

I ordered some billstein b6 offroad shock absorbers and plan to replace the OEM shocks. Is there any easy way to depressurize the airbag ?

I plan on lowering the car into access mode so the air pressure is low and remove vauss connector and hope everything will be fine.

If you know of any easier way to do this it will be much appreciated

There are a few posts on www.disco3.co.uk describing how to change the shocks. Might take time searching for them, but they're there somewhere.

if you can borrow a Hawkeye or similar you can command the car to drop all the air out of the system completely.

i would'nt change the dampers if you have ARC fitted as the roll rate will change and confuse the ecu however.. the easiest way to depressurise is to drop to access, disconnect the battery then jack the vehicle up high to drop the spring pressures then slowly and carefully unscrew the voss connectors in the valve blocks that feed the springs when they start hissing just leave them alone to deplete the air, dont rush this as the voss connectors are very easy to thread in the valve block (£££). i'd wear safety glasses etc when doing this incase the connector whips about. when its stopped hissing crack them off abit more and leave again etc.. Trust me, i'm an Engineer!

I don't think I have ARC as my option doesn't include Dynamic Response.

Don't worry - even if you do have arc/dr, it doesn't make a difference. The Bilsteins are good (but the B6 is not recommended for cars with dr) as are Koni and the Greek Spyros ones. It's a quick job once you find the instructions.

Be careful, check with the manufacturers.
I think it is not compatible with ACE. Malaysia Boleh!

Leo,

Changing the damper characteristic does make a difference to DR, it has to. DR uses accelerometers that measure lateral and longtitudinal accelerations so if different dampers change the roll rate then the signals to the DR system must be different and therefore the system will act differently, whether you or i could tell a difference when driving normally is irrelavent - i wouldnt do it because i dont know what these changes would mean when trying to avoid a stationary car on the motorway whilst doing 70mph. Just my opinion you understand!! Trust me, i'm an Engineer!

Yes,
they are not ACE (Active cornering enhancement) compatible.

From my understanding, the Dynamic Response option is what ACE refers to. As I don't have dynamic response fitted on my RRS, I should be fine.
