VW Electrics bad earths

Hacksawbob

Behind main fuse box infront of (Right hand drive, passenger side) fusebox. there is a "crown" of earths that may want attention.

Gearbox, there should be at least one earth going from gearbox to chasssis, some folks add a second just to be sure.

Engine block to left of engine block to engine bay. Particularly on 2.1 injection engines this is a prone point for failure after you have checked the gearbox one above.
