    as far as i know

    disconnect both battery leads and then touch the two leads together for 10 seconds to discharge any power left in the system.

    maybe someone can correct me.

    i would like to do it to mine but im scared of what might go wrong :S

    You are correct.

    This is usually followed by waiting 10 mins before re-connecting.

    I thought the + and - leads should never touch or am I mistaken?

    I am looking to do a hard reset to reboot my Satnav without removing the passenger seat and unplugging the bcu. A hard reset looks like the way forward but I thought it would be safer to disconnect the + and - leads and earth the + lead with a jump cable.

    Any ideas?

    Not when they are attached to the battery - obviously not....

    Disconnect the battery at both poles following the RAVE procedure....and then wait for 20 minutes for the SRS to discharge, the touch the two LEADS together but NOT ON THE BATTERY, this should discharge the system for a reset.

    Reconnect and reset the Steering Angle Sensor and job done!

    If you are doing a hard reset it is vitally important to follow the correct procedure as there is a pyrotechnic device on the plus lead that explodes in the event of an accident to shut off the power ! incorrect battery detachment and reset can trigger this device !!!
