Q3 (2021) 40 TDI Quattro (Auto) Coolant Fault Light Intermittently Lit.

[Scuba Steve]

I have recently brought Q3 40 TDI Quattro auto, above 60 mph the coolant fault light intermittently illuminates for a period around 2-3 seconds, then extinguishes, this may happen once or twice during a motorway journey. Driving around locally and in town no faults apparent.

The vehicle has been back to to the dealership, no fault found. All coolant and levels are correct and temperature for oil and coolant are within limits, 90C for coolant and around 100C for oil temperature and no faults showing on the virtual cockpit. All electrical connections have been checked and disconnected/reconnected.

As anybody else had the same problem ?
