Red tyre pressure warning followed by traction control on Mway

[Chappers]

Morning chaps,

My car had previously been parked up for a little while before driving it 120 miles yesterday. About 10 miles down the motorway the red tyre pressure warning came up. 3 were fine and one was a little low (1.9 bar) but with no obvious punctures.

Carried on to the services and before I got there I started to get some traction control interventions, to the point where I had no throttle at all and had to turn DSC entirely off to be able to proceed. I pumped the tyre up to nominal pressure and carried on after a more extensive check.

Initially the car was fine and then after a while again TCS started cutting in and I lost the throttle and had to turn it off.

Any ideas what this might be? I've left the car at my dad's, I can get him to check the pressure over the next week... But could it be a wheel speed sensor too?
