    Hey all,

    I have an odd (when are they ever not..) electrical issue on my E34 Saloon.

    Symptoms:
    - Number plate lights come on with interior boot lights when the boot is open, but these all flicker
    - Reversing lights don't always work and when they don't selecting reverse causes the rear fog light tell tale to come on in the dash
    - When turning the lights on the rear fog light tell tale comes on in the dash
    - Rear fog light isn't illumiated in the two scenarios above

    I am, at best, mildly allergic to electrics and I had a quick look at the wiring diagrams and it made my eyes go funny so if someone could suggest where I might find the following that would be great!

    - Rear fog earth point
    - Reverse light earth point
    - Boot interior light earth
    - Number plate lamp earth

    I am hoping these are all in the same place?

    Thanks

    Check where the wiring comes through into the boot lid. It's clipped to the left-hand hinge & the action of opening & closing the boot eventually causes the insulation on the wires to break & rub together resulting in the sorts of issues you are having.

    Pretty common fault on both Saloons & Tourings
