Speedo , fuel gauge, climate control not working - audi a3 1.9tdi

[DB7A3]

Hi ,
Audi a3 1.9tdi 2007 bxe
Car was fine yesterday. Started today and drove a few miles.. noticed no speedo, no temp or fuel gauges , no climate control......but every warning light on the dash now on.
Any ideas where to start?

Thanks
