    Quick one guys,

    Can someone please tell me where the engine speed sensor is on these 4.2 lumps? Have looked around and only found guides relating to other engines (eg B6 A4 1.8T: Engine Speed Sensor (G28) Replacement).

    Don't want to be undoing the wrong one (crank position etc)!!!

    Cheers,

    Adam

    the vehicle speed sensor is on the front axle behind the back of the brake disc
    pretty sure its the passenger side

    just trying to find the engine speed sensor now

    white/grey connector on the firewall just behind the coolant reservoir
    trace it down with your hands
    its a ***** to get too ... in some cases it might even be worth removing the catalytic convertor on that bank for ease of access

    do you have a manual or a tip ??? theres even less room with a tip , but you can lower the gearbox subframe down to gain better access
