Does anyone know what the correct torque settings are for the front and rear bearing hub?

If you're talking about the axle bolt.....

For the fronts, there are actually 3 versions of the bolt - commonly people get the torque and angle setting wrong as its different depending on what bolt you actually have.

12 point bolt without ribbing (smooth underside) : 200NM, then 180 degree angle turn
12 point bolt with ribbing (ridges on underside) : 70nm, then 90 degree angle turn
6 point hex bolt : 200NM, then 180 degree angle turn

Rear:
If bolt is not one of the bolts above and is a spline (tripple square) bolt, then its 180NM + 180 degree turn

Also note:
Wheel bearings must not be subjected to load after bolt securing drive shaft to wheel hub has been loosened.
If wheel bearings are loaded with weight of vehicle, bearing will be damaged. This reduces the service life of the wheel bearing.
It is not permissible to loosen drive shaft bolt more than 90° if vehicle is standing on its wheels.
Do not attempt to move the vehicle without the drive shafts fitted as this would damage the wheel bearing.

When tightening the bolt, first do the torque with the weight off the wheels (you will need someone to press the brakes for the front). Then you can lower the car weight onto the wheel and do the final angle turn.
ALWAYS renew the bolts - they cannot be reused, once removed they must be replaced with new bolts as they are likely to snap if you reuse them (the heavy angle turn permanently distorts them)

I presume from your description this is the first bolt, it's a 12 point bolt, not sure about the ribbing, but it looks very smooth. Do the other bolts (4x) for the rear of the bearing also need to be a certain torque?

The ribbing (if present) will be on the underside of the head where the head touches whatever it is bolted to.

The bolts that hold the wheel bearing hub to the carrier, as in your 2nd picture, are 70nm + 90 deg

Thanks for the info from all, just ordered up a ball joint separator also, just curios as I have seen a couple of different versions of doing this for a golf 5 etc, does the scirocco have any torque settings for these too?
