Ok, so I kind of know it's supposed to be on the right side of the engine, but, I can't see it....It's different to my old 1.6 petrol - any help/pics would be greatly appreciated. Thanks.

Thanks, I'd found that pic too during my searches, unfortunately, mine's different - a later model, 2007. Thanks though.
