Can anyone help and tell me/show me a pic with location of the glow plugs relay on a superb mk2 170 hp 4x4 2l ,CFGB engine code? Many thanks!

In a little slide-out drawer under the e-box (engine bay fuse/relay box). Arrow A points to it:

 

So if I get it right from your picture it should be somewhere under the fuse box where the pointy bit of the arrow is ? TIA

Yeah, looks like the battery is thoroughly in the way, unless that whole fusebox can lift up, which sounds unlikely.

Yeah I'll give it a go and remove the battery see what's going on many thanks for your help 👍
