Cheers for that guy's. It was bound to be a pain to get at, and yes we also feel like setting fire to it at the moment!
Have read on another forum that it is often a problem with the power feed (white wire) and not the starter itself so will try that first. BTW the other forum I looked on was a renault one and they couldn't/wouldn't tell me where the starter was. Just shows what a great bunch of people us 4x4ers are.
