    Disconnecting PASM

    Hi could anyone tell me does diconnecting the PASM system by upgrading the dampers create issues with the onboard system, if so can it be rectified?
    Thanks

    Re: Disconnecting PASM

    Excellent question, I have researched this. It appears that the dealer or anyone with the laptop and diagnostic software can tell the cars computer that PASM is not installed (i.e. 20mm suspension or standard NON-PASM) and then the computer will simply not activate that portion of the logic hence no error messages etc.(These settings are normally selected as the car is being set-up for delivery after they leave the factory).
    This allows you to install standard shocks and not get any system error messages. If change these settings AND you still have the PASM shocks installed they will go into 'limp-home' mode which is a mode during which they firm up quite a bit and no longer self-adjust at all. 'Limp home' mode is actually not bad (If you hate PASM) - it's almost not as harsch as sport mode and if you are on long highway drives 'limp home' mode is not as cushy (causes less motion sickness) as normal PASM mode.

    Peace - drive right

    Re: Disconnecting PASM

    thanks for the help, what happens if you disconnect the dampers without turning of the PASM, does effect any other systems on the car such as throttle or traction control?

    Re: Disconnecting PASM

    You will get error messages and they will still go into limp home mode but other systems should continue to function as PASM shocks to not control the traction control or stability management. They receive and act on information but no other system uses them as a 'sensor'. Of course your traction will be compromised to an extent as the shocks in limp-home mode are more firm.
    There is a quick way to disconnect PASM but I better not get into that here.
