This problem is more common than you might imagine and applies to a lot of different makes and models. It’s a simple cases of physics, in the end: The petrol is being pumped into the filler neck at a decent rate, sometimes enough for some splash-back to occur as the fuel hits the side of the filler neck and bounces around.

The problem will be much worse if the filler neck can’t 'breathe' (air has to leave the tank for fuel to get in - physics again) so make sure there are no blocked breather lines or holes inside the top of the filler neck.

Beyond that, the best advice is to try turning the fuel nozzle, say, 45 degrees each way from vertical to see if that lands the fuel in a more agreeable place in the filler neck. Either that or you’re stuck with trickling the fuel into the car at a slower rate (the rate of flow of the nozzle is adjustable according to how far you pull it).

This is another classic example of body-computer-fault behaviour. The body computer on a modern car controls multiple (hundreds, in fact) functions such as the heating and cooling, dashboard, media and entertainments, wipers, lights and, of course, the central locking. If the computer has a glitch, the central locking can develop a mind of its own.

Ultimately, you may need to replace the body computer, but this is potentially a warranty job since your car is a 2019 model and should, therefore, carry seven years of factory cover. Take it back to the dealership and have the situation assessed.

The first thing to check here would be how well the door and window rubbers are sealing. If they’re not sealing absolutely 100 per cent, a whistling noise at higher speeds is often the result. This technology has come a long way but, ultimately, it all depends on the rubber sealing the glass and the door against the rest of the car. Inferior quality rubber has been noted in some cases, and other times a single bad batch of rubber has been to blame.

But the first thing to do is open each door and make sure there’s not a small twig or piece of tree stuck in the rubber as this can cause the same problem. At least the latter is easy to remedy.
