2016 Golf sometimes heater cannot be turned off

[Idle]

Might be flaps not fully closing or tap not shutting off.
My aircon (2013 Golf TDI) was thoroughly inefficient at delivery, many passengers commented on it.
Complained about it at the first two services and was assured all was perfectly normal -- at the third service I forgot to grizzle about it, and they fixed it...
Aircon is now as good as any I've used.

Thanks Idle do you know what they did to fix it? My aircon is also pretty *****.. worst i have seen on any of my cars..

Air vent blowing warm air? - GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum

One person measured the air temp coming from his vents with AC off and temp set to "Lo": between 6 and 15 degrees above ambient temp! (US forum, so I assume Fahrenheit)

[Sage]

15 degrees Fahrenheit is actually Negative 9c so it was above ambient then i assume he was talking about Celsius!

And yes mine comes out piping hot even when i was driving around with it being 14c outside

I assume that US post is interpreted like this:

Say, 70F = 21C. Increased by 6F = 76F, so 24C. Increased by 15F = 85F, so 29C. So on a 21 Celsius day, a range of Celsius 24 to 29 degree air coming out of the vents. That pretty much accords with what I was feeling. (all temp numbers approx.)

Either way, the result is hotter than ambient air is coming out those vents!

[Sage]

well put!

Sorry, it was at the 2016 service and my memory isn't good.

All the invoice says is "Carry out campaign 45D4 - update ECU software"
"Criterion 01 and 05"
Maybe some-one more knowledgeable than I can interpret that.

I have this issue on the MY14 Highline wagon. If I turn on the climate, set it to a low temperature or "Lo", blast it for 30 seconds and turn it off, the warm air stops.


Steps to reproduce:

1. Set climate to 26c at end of trip.
2. Turn off climate control.
3. Following day, drive car. Leave climate off.
4. Warm air.

It appears that the heating system is still activated even when the climate is turned off but still sues the climate settings to determine whether to blow the air or not.

Curious to know if this was fixed on the 7.5.

No. My 7.5 Trendline had this problem. So far the GTI (also 7.5) seems not to (touch wood).

That may not have been specific to the aircon?

Mine has this same issue. Mid 2015 build, just done the 3 year service. It happens seemingly randomly...
