Hi All,

I have found this site to have a wealth of knowledge and I would like to thank all of you, I have been a silent watcher gleaning valuable information.

I have an issue and have read so many threads on many sites now and still can't get a grip on my issue. I have a 2005 Octavia 2.0TDI (140) 1ZU

issue is starts first thing every morning Engine block light and Glow Plug light come on and starts first crank. after that no EBL or GPL and wont start until those lights appear and go out.

There is much talk of Relays and I need to start with Glow Plug Relay but numbers are confusing me... under the steering column I have the following
