The glow plug relay is the 'black box' unit fixed to the side of the coolant header tank (LHS engine bay as you look at it).
against the bulkhead, next to the ecu
when the glow plug light is flashing during driving it is not the plugs that need replaced it normally means you have a bulb blown most commonly one of your sidelights and once replaced your glow plug light will stop flashing
I have the same car, so this question is easy. First locate car battery on right hand side of car (as standing with bonnet open at front of the car ). Then just behind it there is a metel bracket with a Glow plug heater relay box attached to this bracket ( slide fit , held in place with one screw). The relay is under neath the main area of the metal bracket ,and attached to two wires - unscrew the nuts, and one connector pin block (either 5 pin or 6 pin deppending on model) unclip. If your 406 is the 5 pin relay you have mk1 series 406 . If the relay is 6 pin , you have a mk2 406. Hope this helps herbie44
