No heat out of vents.

Hey guys,

About 2 years ago I had my engine coolant thermostat kit (part number 059115389P) replaced by the dealer when my heater wasn't working then. That fixed the issue.
I have a feeling its the same issue again. Has anyone replaced this themselves? Any tips?

My 2014 Q7 TDI had no heat about 1.5 years ago.

It was an electrically controlled coolant shutoff valve in the driver side wheel well.

Pretty easy to replace.

You may want to check it before assuming its the thermostat.

thank you.
