Urgent Help needed - where are the Injectors

[decho]

Can anyone tell me where to find the diesel injectors on my v6 signum. I want to try wiggling/disconnecting the connectors to see if one of the injectors is causing a problem. I am not technically minded but have drawn a circle round what I think might be them - there are also 3 at the rear of the engine. Have I got this right? if not can someone point out where to locate them on the diagram.
Thanks,
Decho

Took the cover off mine (for the first time)
Yip, those are indeed the injectors
At first glance from the photo I thought they were the glow plugs due to the electrical connections
Turns out they have both!

Access to the rear ones looks fun!

Just make sure that when you detach the injector from the injector pipes you don't break the seals
If you do, then you will need to replace all the seals
