Sounds like it's ok then. The most important thing is to check the wheel through it's full rotation lock-to-lock to see if it correlates with the reading in the driver.
Have you tried updating the firmware as well? Probably best to check what firmware is installed on the wheel first (check the manual). The latest is 750B...

As for the sound, it should be fairly quiet in operation (apart from the fans, which you can turn off if you want). Being belt-driven it should feel and sound smooth. Could just be a case of not using the thing without headphones before.
Yeah I think so, it's kind of a gentle noise rather than something that sounds 'wrong' as such, but it is clearly audible. It only does it when turning so I'd imagine it's the sound of the belt/motor that I just never picked up on. I suppose something built like this isn't going to be totally silent. The motor itself does whine quite a lot, but I've read that's nothing to worry about. I've not tried any firmware updates, to be honest I was happy enough with the wheel and didn't want to risk any potential issues. Reading the feedback pages on the Fanatec firmware site, really put me off to be honest.
Right, so the PC settings all seem okay then. As I said, the FFB test kinda violently 'rattled' the wheel, which I presume is correct, and I tested the wheel as you recommended at both right and left until full lock. It seemed to correspond exactly with the readings in the driver.
Bizarrely, though, since doing the tests on my laptop then plugging it back into my 360, it seems to be much better. I don't know if I may have reset something, but I doubt it as the PC settings have nothing to do with using the wheel on the 360. One worry was how the wheel seemed to stop auto centering when switching on the wheel, but when I plug it into my PC and set it to PC mode, the wheel whips into perfect centre alignment so I don't need to worry about the motor not working at angles close to centre. The fact that the 360 fine tuning the auto correct when switching it on used to slowly rotate round, and now doesn't, might be down to it being wireless or something. Certainly, plugged into the PC by USB doesn't seem to have that issue.
Maybe I'm just thinking I'm just remembering the ffb to have been stronger than it actually was and am a bit overly paranoid about it. It did take a good few sudden hard slams (he was pretty much spinning the wheel with one hand trying to correct a spin, then back the other way) but it's not like he totally abused the thing.
Plus, turning long sweeping bends at high speed is very strongly resistant, and going over rumble strips etc give the wheel a nice 'tug' downwards so it can't be broken. The wheel does feel loose in the middle at slower speeds, but then it would do given there won't be any resistance when turning at slower speed anyways.
I'm not sure if plugging the thing into the PC could have done anything positive to it, but situations like feeling the car slide from the rear and the wheel whipping back to correct itself seems a lot more prominent now. Maybe again, I'm remembering this mechanism to have been stronger before than it actually was. It's not really designed to be really 'hard' as such, but more subtle anyways.
Thanks for all your help though mate, trust me it's really appreciated
One final question if you don't mind, as I've been bombarding you with them so far, but I think it might say in the manual not to plug it into the 360 via USB, have you ever done this? I'd imagine that using a cable would provide a more stable communication between the two devices, and given how the 360 struggles to auto centre when fine tuning (when you press the 360 button on the wheel) compared to how the wheel just whips perfectly into centre when plugged into my PC, then surely it would be better to plug it into the 360 too as it could be being caused by wireless connection issues perhaps. I'm not sure if this would actually work, or screw it up completely though.
