Coolent issues

[dunes]

My t6 is showing coolent issues after my mechanic changed the fan motor for the radiator and coolent pipes
Took it back to him and he pressure tested it and said it was fine but the light is still on after a long drive it came on in the morning previously it came on during at least 5 hours driving
My t5 had the light go on and the mechanic and Vw could not find the fault then last week i went on a 8 hour drive with the light on as they could not fault it then the engine died
I'm so over VW now i i'm going to sell both and buy a jap car

Probably airlock in the system.

It's it's a complex procedure to purge the air out the system apparently.

Or sensor is issue.

You would need to say some vcds scan data for more accurate diagnostics.

Did your mechanic use a vacuum system to fill it back up?
