Q4 e-tron - Speedo & TPSM issue

I had an issue with my Audi Q4 e-tron 210kW 45 82kWh Sport (2024) last week

The TPSM error appeared on my dash, my speedo stopped working & my audible seatbelt sound stopped sounding.

I reset the car settings back to factory but made no difference.

As it was late at night, Audi sent a generic AA engineer who said the car was too new to diagnose issue on. He suggested a software update maybe required from the dealer.

I was in London, nearest dealer was in Brentford but lived in the Midlands. He suggested I drove the 130 miles back home using the Waze apps to track my speed as the tyre pressures etc were otherwise fine.

When I got back home and restarted the car back in the morning to head to the dealer, typically everything started to work again.

The dealer had the car for a week & found no faults apart from a "passive" issue which was of no significance & have advised that I drive the car & see how I get on.

The response gave me no confidence & am reluctant to drive the car a long distance.

Has anybody else experienced this & have any suggestions that I can share with my Sytner dealer?
