Yesterday I drove south from Tyneside. Halfway to Scotch Corner, the tyre pressure warning came on but there was no problem with the feel of the car. At Scotch Corner I stopped for some food and did a visual check on the tyres, set initialisation once and drove on South. Soon after, the warning came again so I stopped at Wetherby and checked the pressures on the machine there. The rear tyres were down to 27 and 29 psi before the reinflation. I reset initialisation once and drove a further 200 miles without a problem.
I don’t know why the video says to reset initialisation 3 times - I’ve never done that.
