vectra c diesel problems

[george120879]

Recently after having that icon with the car and spanel tool on my screen i went to someone that had a error code reader and the code reader had found that my glow plugs need to be changed,so i changed them.
But still the light was on the dashboard.
Then i changed the glowplugs relay,but the light is still on.
Does anyone know any good engineer for vectra c diesel?????In london or around even couple of miles far.

Also on the vectra c diesel does anyone know if there is a fuse for the glow plugs ,and where is it exactly?
