Background,

Engine running and occasionally the temp gauge would go to the red, warning beeps and screen come up, coast to the side of the road and then drops. Showing same characteristics as a low coolant issue or vapour lock. Checked the levels when cold and it's fine.

Booked it in and they though they fixed it with some diagnostics.

Came back the next day. Further diagnosis: possible mechanical water pump failure.

Vehicle is a 2014 vrs diesel (5e) with 60+k.

Anyone else had this issue?
