caddy glow plug/brake light problem

[bruwalsh]

Hi lads,
Got a bit of a problem with 2005 caddy. It started with glow plug light flashing and bit hard to start. My local vw dealer informed me that the most likely cause was a glow plug control unit with no. 461 on top
Another (maybe unrelated) problem has since developed that my brake lights won't switch off. I replaced front and rear pads and noticed the lights staying on the next day. Cant seem to link replacing pads with faulty brake light switch but could there be a link?

I replaced brake light switch according to these guidelines

Now no brake light at all:mad

The switch felt like it clicked home and I don't think that was fitted incorrectly and I don't really want to take it back out. There is power going to the switch.

The only thing that we did when changing pads and checking glow plugs was to disconnect a relay on top of fuse board (458) in engine bay, this stopped the relay light flashing but ESP light came. We then plugged it back in.

We ordered a new on of these from vw to arrive tomorrow along with glow plug control unit.

Any help greatly appreciated,

Brian (newbie)

Check your brake lights are working.

hi again
changed the brake switch and sorted the back brake lights, still got the flashing glow plug light on the dash , changed the glow plugs and the glow plug wiring harness and still got the flashing light ,anyone help on fuse/relay location.regards d.

the flashing glowplug light may be indicating a stored fault code.
try disconnecting the car battery for 10 mins. or have a fault scan.

hi kite
issue now resolved, changed the brake pedal/switch, part no;S1k2945511rdw, bit tricky to locate and turn untill it clicks! happy days. still can't work-out why they would link that to the g/p light, but anyway done, so thanks again for your time. d.
