Got this back from Volvo Car UK:

"Our Technical department advise that they have been notified of a number of instances of this occurring at a specific mileage (622 miles, which is 1000km). They are currently developing new software to correct the problem, and this will be launched to our authorised repairers as soon as it is available.


We would recommend that any customers who experience this problem should take their vehicle to their local Volvo dealer for investigation and diagnosis."
