Instrument panel not working

I wish to ask if anyone might help concerning my car listed above w203 saloon.

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

The fuel gauge, parking brake, speedometer, main beam, plus the sound for all indicators etc.

The windshield wipers and horn worked as did interior lights although the main lights were fully on when driven.

The rear lights and brake lights work as did the horn. I do not know if it is related but I have had a SRS light on for a day or so and have checked the connectors under front seats.

Please help!
