Exhaust warning light

Not seen this warning light before, picture of exhaust emissions and a thermometer. Does it mean I’ll end up with a bad ass sounding exhaust soon? Drives fine On break now so will of cooled down, what causes it, is it ad blue failure? Renault premium truck 65 plate. Cheers.

Is it a euro 6 truck?..Might be the regen light if so…As euro 6 trucks run hotter i believe…But i doubt your renault is going to sound like a v8 anytime soon…
