Alright it gets complicated...
I'm assuming you have a 4L (2005-2015) model.
It will be in the under bonnet (hood) relay panel.
It can be any two of five relays depending on engine and year!
For petrol engine models up to June 2009 it's relays A1 and A2.
For petrol engine models from June 2009 it's relays A5 and A6.
For diesel engine models (3.0 and 4.2) it's relays A5 and A6.
For diesel engine models (6.0 V12) it's relays A2 and A4.
For all fuse and relay information (RHD & LHD) see here:

All oil pressure is ok,just no power some mechanic said what is intake camshaft,and diesel sound is just for few seconds then starting engine, 100000 miles....
I have a Vauxhall Vectra X reg 1.8 SRi
Recently it started sounding like a diesel engine (ticking noise).
When driving it is a little bit jumpy, as if something is blocked and then it gets unblocked or some kinda pressure drops and then goes back to normal and then it happens again a few times during the journey.
The vehicle has brand new spark plugs and recently had an oil change.
It currently has 98000 miles on the clock.
Thanks for your answers in advance.
