Coolant Light Remaining on

[McNeil]

2.0t Avant 6MT mileage: 174k

Coolant light recently came on without any vehicle overheating, after research here on forum and inspection I noticed leaking rear coolant flange.

Replaced:
Rear coolant flange
All associated coolant lines
Coolant temp sensor

Light remained on.

Replaced Coolant overflow tank.

Light remains on without overheating or coolant leaks.

Suggestions on what to diag next?

If you have coolant in the bottle and the low coolant light is still on, check for power to the electrical plug. If you have power, there’s something wrong with the bottle. If there’s no power, find its fuse and check it. Replace it if its blown.

If the fuse is good and there’s no power at the plug, you might need to splice in a new pigtail connector.

And if all that electrical stuff checks out, then you might have a cluster issue, worst case scenario.

I doubt its a cluster issue, probably wiring. When these sensors fail, sometimes coolant can leak into the wire harness and that shit can migrate down the harness and corrode it.

did you bleed system thoroughly after the flange replacement
