    Recently changed my battery and discovered the battery vent pipe was missing. The grommet is still in the well wall.

    When pushed through the grommet i the pipe long enough to exit underneath the car?

    thanks

    Only needed if you have an old-style lead-acid battery. Not needed on AGM batteries.

    Hi Taz,
    Yes it’s a standard Bosch battery. Hence wanting to know the routing.

    If the vent is used it will have a 90 degree fitting and a plastic pipe from Halfords etc

    Hi Mike,
    Yes have a new tube. Trying to work out if the tube is simply vented into the void in front of the foot well or if the pipe comes right down and out of the underbody.

    it’s not clear from the parts diagram

    For the most part, yes, but some AGM still use the vent tube for some reason. The Odyssey I have in the Ferrari doesn't need one, but the one I used in the Vette does.
