I have my A4 QSE 3.0,I was just driving into a pub carpark to park up for lunch, just parking up so I was moving really slowly, I heard this loud "BEEP" I looked down at dash there was a Xmas Tree of warning lights come on and across top said something like TPM malfunction? Had Tire pressure warning light, Steering angle light and a few others all lit up?

After the meal I started car, with no warning lights at all and drove home without issuses?

However I dug out my code reader and there was 3 codes stored

Two were the same U111300 + U111300

and the third one was P305400 ? I think this relates to a starter not working but that's fine? That could have been generated when I had a dead battery a while back? I just never had a look and cleared any which the dead battery might have caused.

I have since cleared all of them will see if any return?

The other strange thing which happened on my last drive of the car was the MMI screens shut down and restarted? like it was re-booting of something, all of the displays when off and the Map Display, was off for only a short period like a few seconds and then all came back on for no reason?

it's Most odd.

If anyone could shed any light on what's going on I would be most grateful
