All,
Have checked the car over Thermostat works ok starts to open at 87oC and fully open at 102oC. Bleed and refilled system. No air locks. They have checked the car over with an infared thermometer. Radiator gets evenly warm as do all pipes. There is a very small difference in one of the pipes leading to or from the heater matrix. Diagnostics have revealed nothing. The temperature sensors report no faults all electric fans operate as they are meant to.
In the end the garage has passed it back to me to try an engine flush with an audi flushing agent. One thats not stocked on the shelf. The reeled of a technical bulletin titles engine not getting to temperature and particles in the coolant. There was no particles in the coolant with my car.
So Not Thermostat.
Not Water pump.
Not Temperature sensors.
Not Air lock.
Any ideas???
