I’ve had a 2021 EQC AMG Line for just over a week and I’ve covered 700 miles. The Speedo Display Screen behind the steering wheel is now blank / black / off while I am driving. The MBUX touch screen is fine so I can see sat nav, radio and all the other functions. I just cannot see the speedometer display. Is there a fix for this? It’s disappointing that an electric car already has an electrical fault.
