On the first picture, they are directly underneath the aluminium bit.I've got my bonnet open at the minute, got the tools, but no idea how to get at them. Can't fit my hand in and no prospect of unbolting the whole top of the engine.
Did you manage to get them out? If so, how?
I'm just heading out now to try and find the relay module mentioned on the post about a fiat stilo (sorry not allowed to post the URL as haven't posted enough times). Even if that tells me which one is faulty then I still won't be able to access it though.
