Blank Driver information display and no warning chimes

[Valocol]

Hi all. I’m new to the forum so thanks for your help. I have a 2010 A6 c6 2.9tdi sline SE and recently in a drive my driver information display went blank about 30 mins in and stayed off. Next day it came back on from start but again died after about 20 mins. It has stayed off since (about a week). As well as the display not working none of my warning chimes are not working such as lights left on, low windscreen washer levels etc and I can’t zero the digital trip display also. I’m not showing any codes. Has anybody any similar issues I’m hoping it’s not a replacement binnacle?? Thanks all
