I had read that thread thanks but it did not seem to give a definitive answer on the subject.
I have now downloaded the Karoq 'Maintenance' workshop manual and it states the following after the initial oil fill:
– Lower the vehicle.
– Start engine, engage a gear and allow gearbox to rotate for about 2 minutes.
– Switch off engine and unscrew oil drain plug.
– Check oil level, if necessary top up gear oil again to lower edge of filler hole.
None of this gets mentioned in the Karoq 'Propshaft and Rear Final Drive' workshop manual procedure for replacing the Haldex oil But it does say the oil temperature must be between 20 °C and 40 °C when checking the oil level.
