All gauges in dash not working

Hello,

I wish to ask if anyone might help concerning my Mercedes E350.

I used the car to date fine with everything in working order.

Today I went to the car and it started okay, but the center dash panel was completely out with no indicator lights or sounds working at all.

The general lights are for seat belts, fuel gauge, parking brake, speedometer, main beam, plus the sound for all indicators, and for the doors opened.

The windshield wipers and horn worked as did interior lights.

Interestingly the car behaved perfectly otherwise, although the main lights were fully on when driven.

The rear lights and brake lights did work as did the horn.

Please help!
