Please can someone tell me where my spark plugs are located. A website for A diagram would be a great help if possible.
Thank-you sooo much in advance!

    The Q45 has an individual ignition coil on top of each spark plug, i think there is a large silver plastic cover over the top of the engine, may be secured with some allen key bolts. Remove that you will see coils I think they are secured each to the valve cover with two bolts (12mm head). Remove them spark plugs are under neath 5/8 plug socket needed.

    under the valve cover you will find the coil, the spark plugs are underneath the coil.
