Just come out of indie garage for routine maintenance, radiator and condenser only six months old, sudden spike in temp from 90c to 120c in matter of 10 seconds, air con is not cold and gassed up at merc garage when new rad fitted, Merc garage just got back from the other day said they could not find any fault codes, put my icarsoft mb2 on it today when temp spiked and no faults, any thoughts, not air blockage as done the usual bleed operation.

Stuck Thermostat? I mean, if it suddenly spiked. I know its not easy with today's temp, but did you try turning the heaters on to see if it bought the temps down again?

I was near home and didn't bother, the merc garage the other day said no fault codes were present, the other week when it did the same thing when I put the heater on high it blew cold for a bit, still ain't that hot on high,

They didn't use an airlft for filling coolant solution most likely
