Anyone know what the temperature of the coolant and engine should be in an Audi TT?

The coolant sensor has been coming on, coolant level was fine, white smoke/steam started coming out after being driven for a little while. Sensor part replaced, radiator flushed and coolant replaced, sensor still lighting up on computer. Engine temp 90C and coolant 121C.Anyone know what the temperature of the coolant and engine should be in an Audi TT?You could have a faulty water pump or thermostat, it also could be a faulty thernostat housing, on the other hand it could also be a faulty coolant temp sensor that was supplied to you.Anyone know what the temperature of the coolant and engine should be in an Audi TT?180-210 f
