So i have an issue with my golf mk7 tsi. My heater pretty much doesn't work. If i'm driving for 20 minutes a so i'll get some warm to hot air from my driver side vent but nothing from the centre console.
When i put it on AC and maybe below 22 degrees or something the centre console vents will be pushing a heap of air but then as soon as i put it above maybe 26 degrees nothing really comes out.

I've checked with OBD11 and no codes, my coolant temperature is fine and i have plenty of coolant.

Any ideas?

Cheers
