As yours is a 2.2 , and thus has a Bosch ABS system, the Nanocom will have minimal capabilities to monitor its operations and none to configure them.

For the 2.2 the Nanocom has only recently been able to code new injectors and undertake a pump learn, noting there is no facility to do pilot correction learn on a 2.2 ‘s engine management so it wont be on a Nanocom or any other diagnostics tool.
some have still reported issues with coding 2.2 injectors.

No DPF forced regen capability, limited monitoring.

Alarm unit support (ALM) , this is the unit that replaced the green 10AS alarm unit, this was developed for the CH version of the ALM unit however blackbox “believe” it’s ok with the DH version but have not tested it. some have found configuring the ALM unit can cause issues and immobilise the vehicle.

You can now clear the oil service message with the Nanocom.

So for the 2.2 Nanocom is a mixed bag, and not as good as for the 2.4.

If you are looking at a tool I would investigate the GAP IDTool, the downside is it’s locked to one vehicle, however I think it has more capacity than the current version of the Nanocom.

Has anyone noticed this remark? I find this strange in two ways: a) the sensor is mounted on top of the hub, so how should anything drain b) there should be no oil in a 2.2's hub but grease

I’m glad someone spotted it in my original post. I guess the previous owners put this in. It was last serviced by AstonMartin dealership(owners company. You’d think they’d know better. I presume I can just drain this out and fill with one shot. Neither of the hubs are leaking.

Ok, that answers b) - incompetent dealer, not unplausible

What about a) - how did/do you drain the oil? There is no drain plug and the ABS sensor is on the top of the hub (the obvious solution, turning the axle upside down was already suggested

)
You could use an oil pump maybe, but your orignal post confused me re the draining.

I wonder if they removed the sensor in order to fill the hub to the top, and then refitted it incorrectly. You can never tell, and Aston Martin technicians will likely not be familiar with old school landrovers.

Just drain your axle/diff casing..you will likely wonder why its so full / overfull..I certainly did..🫣🤣..
I don't think the sealing is that effective ..
I just re filled with grease and until I do my front axles I most probably have a rather fluid grease in the housing..😳

On the foxwell question.. that model is no longer supported, but they will have an updated model..
But any half decent scan tool with the option of European makes will likely fo the same job

I’ll probably use a vacuum pump to drain as much as I can from the hub and stick in some one shot. I’ll have a chance to check the rings then. I also need to check the diffs and transfer box to make sure they have the right oil one way or another.

I’ve ordered a Foxwell NT680 plus as that can read live values and steering angle sensors. I work on other cars as well so it would be a benefit too. If this doesn’t fix the problem I’ll invest in the NCom03.

Speaking to specialist LR garages it’s a fairly known issue ranging from faulty ABs units both Bosch and Wabsco, to steering angle sensors, wiring and wheel sensors. The vehicle thinks it’s working correctly or it would flag a fault light so it’s just a case of ticking off each item. The ABS modulator is the most expensive bit but only £200 exchange if I’ve found the right bit.

First job reluctor rings and sensors.

Wonder if they over filled the diff because the seals had gone which filled the hubs as well, is this likely or possible with 60k miles?

Don’t think they fitted incorrectly as appeared ok and bold was very stiff and corroded
