  • Clonk when starting a vxr astra

    just been out for a drive in my Friends Astra 2008 Astra VXR and when he starts it he gets a Clonk from the engine bay ?
    is he the only one
    only mods on the car are a Blue Fin and remus exhaust system

        thats more like a click, but thats when you hit 15mph.

        I get a slight clonk when i select my gear, but no knocking as it were.
        And before people say anything, yes yes i do use my clutch, and it just the noise it makes when it goes in the gate
        Whats next?!?!?

            dunno, seems a bit strange from an 08. Have you checked all mounts?
            Whats next?!?!?

                  If it's only on start up - could be the exhaust hitting something?

                        My blue astra used to give a rattle/clonk noise as it was started sometimes but it was an exhaust mount not right and was just vibrating against something else, if he aint happy with it then get it back to dealers to get them to have a look at it.

                          My corsa does it some times when i start it or if i shut the boot ,before i start it. I think my clonk is from the exhaust, its more of a tinny clonk like a heat shield moving.
