No it hasn't come back fingers crossed of course. It was this year he had it done though and is a 16 plate.
They initially changed something (tensioner maybe?) and it kept doing it. He then went back and they changed the whole cambelt etc.
The pressures aren't checked at all, it is the rotation of the wheel. Definitely have a good check on the tyre though for anything stuck in it.
I had to get a puncture repair done on a tyre couple of weeks ago when it beeped at me and saw a nail in the tyre, I was loosing pressure though.
Is this when cornering, as it could be the electronic torque management (XDS) braking inside front wheels which seems to make the steering wheel go lighter and turn easier into the corner if you're pressing on.
