Evening all, got home from work today and shut down the car as per usual, foot brake, into 'P', and then pulled the handbrake button to put the handbrake on, then released the foot brake. Waited 30 seconds or so and turned off the ignition, got out of the car and all seemed fine.

Yeah I'm completely baffled, wondered if the coolant still circulated after it was switched off, then thought why would there be air in the cooling system. Really want to stay away from dealers until it's done a few more miles, but will give them a call if needs be.

All of mine have made all manner of noises after they stop. It sounds very strange indeed, particularly if you lift the bonnet, but I can't say I've ever questioned it because early on other people were commenting on it too. I just think my car likes a bit of a chat before I go

Same as fruit here, mine did it to start with and the coolant dropped to the minimum level @ 5400 miles been fine since and my dealer told me the same.

1. Bad wheel bearing
A defective wheel bearing can be the cause of humming noise in your VW Golf. The most common sign of bad wheel bearing is grinding or humming noise in the cabin from the direction of the affected wheel. Sometimes other symptoms may also appear, a knocking noise when cornering, and vibrations in the steering wheel or the whole body.
2. Uneven tire wear
Unevenly worn tire tread can also cause humming noise in VW Golf. Tire cupping or scalloping is a type of uneven wear that is known to cause humming noise at high speeds, and is often mistaken for a bad wheel bearing.
3. Tires with large tread blocks
It is possible the humming noise you’re hearing while driving your VW Golf may not be due to a defect, but because of the type of tires you’re using, especially if you started hearing the noise after installing new tires on the rims. Tires with large tread block pattern are known to be noisy on the highway.
4. Transmission problem
If low-pitched humming noise is coming from under the body of your VW Golf, through the floor, it could indicate a problem with the transmission. But it is not common to just hear the humming noise without any other symptoms: clunking noises, erratic shifting, etc.
Conclusion
There are many reasons why your VW Golf is making humming noise at high speeds. When looking for the reason, you should always start with the most obvious cause, faulty wheel bearing or damaged tire.
