Don't miss
- Make sure that you are familiar with the relevant safety instructions for the use of pressurised containers and industrial gases.
- To stop "“unfiltered”" air entering the air spring system, the air spring may only be »recharged« with the gases listed above.
- Most of the gas will be replaced with the filtered air from the air supply unit once the suspension has twice moved up and down to these settings.
📋 Procedure
- Detach cover of packaging.
- Remove union screw (arrow) from residual pressure valve.
- Close valve on gas cylinder.
- Make sure that you are familiar with the relevant safety instructions for the use of pressurised containers and industrial gases.
- Connect air suspension strut charger unitVAS 6231 and adapter T10157 as illustrated. [Note: To stop "“unfiltered”" air entering the air spring system, the air spring may only be »recharged« with the gases listed above.]
- Set restrictor valve to 2.0 ltr./min (arrow).
- Charge the air spring with gas up to approx. 5.0 bar, using several separate bursts of pressure.
- Disconnect air suspension strut charger unitVAS 6231 from adapter T10157; gas pressure in excess of 3.5 bar will then be released.
- After installation, set the suspension to the raised level setting and then back to the normal level.
- Repeat the procedure. [Note: Most of the gas will be replaced with the filtered air from the air supply unit once the suspension has twice moved up and down to these settings.]

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
