Funny thing is, I removed the VCU at the weekend as I feel it's stiffened up. It's done less than 40K miles!!
I whipped the NSF wheel off to check the pads, this is when I noticed the sawtoothing. I've now swapped the front tyres to the rear and visa versa. The rear tyres have done 3,000 miles. I've driven 50 miles on the perfect former rear tyre and the sawtoothing is happening already.
It's only evident on the NSF tyre. The previous tyre fitted (Goodyear Wrangler HP) showed no evidence of sawtoothing or unusual wear.
The steering works as it should and the suspension doesn't appear to have anything amiss either, as I'd expect with under 40K on the clock.

I've got 215/65/16 Yokohama Geolandars.
The 2 fronts are fitted last June @ 34500 miles. It was running 2WD.
I then had the rears changed to match the fronts in October @ 37,000 miles.
It was an then put to 4WD again after the MOT in November.

My ZS180 does it on inside of both rear tyres, except with the original Michelin Pilot Sport tyres.
I don't understand how it happen on 1 front tyre.
Edit.
I had a few minutes this morning to take a closer look at the OSF tyre. This is also showing sawtoothing but nowhere near the extent of the NSF.

The V6 auto and Td4 manual use the same drive shafts.
Only the PG1 box uses different shafts.

here is what I have found out ps my nearside front is the same
Saw-tooth wear Saw-tooth wear is a stepped wear pattern on the individual tread blocks → Fig. that can cause increased tyre noise. The saw tooth is caused by uneven deformation of the tread blocks in the tyre's contact patch. Saw-tooth wear is more pronounced on non-driven wheels than on driven wheels. New tyres are more susceptible to saw-tooth wear because of the greater elasticity of the high tread blocks. As the tread depth decreases, the tread blocks become more rigid and the tendency to wear in a saw-tooth pattern decreases. Appearance of saw tooth A - Tread block of a new tyre; seen in direction of motion -arrow 1-, tread blocks are equally high in front and back. B - Development of saw teeth; seen in the direction of rotation -arrow 1-, tread blocks are higher in front -arrow 2- than in back. C - Seen in the direction of rotation -arrow 1-, tread blocks show greater wear in the front section of the saw tooth-arrow 3-. Pronounced saw-tooth wear can lead to customers complaining about tyre noise. Pronounced saw-tooth wear occurs under the following conditions: t toe values are too high t tyre pressures are incorrect t tread is coarse and open t tyres are fitted on the non-driven axle t very fast cornering. non-directional tyres In the event of saw-tooth wear, the direction of rotation of the tyre must be reversed. If saw-tooth wear is especially pronounced and tyre noise has increased, interchange the tyres diagonally. This will reduce the saw-tooth effect. On front-wheel-drive vehicles, this effect is intensified by the greater wear on the front axle. Tyre noise will be somewhat louder immediately after the tyres have been interchanged but will return to a normal level after about 500
1,000 km have been driven. Directional tyres In the event of increased saw-tooth wear on the rear tyres in particular on front-wheel drive vehicles interchange the front and rear tyres. In the event of increased saw-tooth wear on the outer edges of the tyres on one axle, turn both tyres around on their rims. The left-hand wheel must then be fitted on the right side of the vehicle and the right-hand wheel on the left side

Thanks Scarecrow243
I have noticed lots of tyre noise at slow speeds, particularly when turning.
I think I'll rotate the tyres to reduce noise until the tyres are worn down some more. Hopefully this effect with not be able noticeable then.
I'm glad I'm not the only owner with the same issue.
Once again, thanks.

had the same on the rear of my X-Trail. tiz common on 4x4's - particularly SUVs apparently.

it used to happen a lot on the early freelanders and LR did a recall and re set the back end set up exactly what they did I do not know I think it was something to do with the tracking and it only happened on the back

sorry but its not only 4x4 motors it happens too the net is full of different motors doing the same thing so we aint special

You are rite, I don't think MHM was implying otherwise. It's a common problem on lots of FWD cars, but normally it's the rear wheels.
I just thought it odd to see it on the front of my Freelander. Especially as I only noticed it on some nice new tyres.
