Tpms failure

[Delboy]

Well is everyone suitably hungover?

On the drive down to London yesterday the tpms did not work at all with a malfunction warning on the dis.

Prior yo that a few days ago the left rear wheel wasn't reporting info so I filled the tyres with air and initialised the tpms and it came back and was fine.

But like I said now there's no wheels reporting, any ideas, is it normal for a total loss of all wheels at the same time on the Mmi?
