Thanks...the question was where the hell is the starter in this car. Unfortunately, despite having followed all your advice, I can't seem to locate it. Does it project outwards towards the firewall? I've changed starters on regular American cars, but this thing is really cramped down underneath. My only question is not how to diagnose the problem, the problem is where does it lie in relation to the engine and what markings should I be looking for.
Ok - sorry Ted - misunderstood. I've never removed one of these so I did a little google work. Figured it must be quite different if you're asking these questions. Well, it is. Here's a link you might find helpful...

Looks like a real pain in the...
I did a quick google image search, but did not find any pictures of the starter in the engine. I didn't look exhaustively, so you might have better luck if you try. Either way, these two links should get you going.
