Blue Box Light on Dash - Valves & 4
Driving today I noticed that a blue box appeared on my instrument display, of my 2021 GLS63, bottom left corner under the auto start stop symbol, looks like 2 engine valves in a V shape and has a number 4 in the lower right corner of the box, anyone know what this is please?
The box comes on for about 3 or 4 seconds then goes off, then back on again in a repeating sequence but I dont think it illuminates when I’m stationary, I may be wrong on that though.
Sorry for the poor quality picture.
Thanks
Carl
I appreciate the reply, it’s reassuring that it’s ok to do that.
