I have a 2015 Tiguan with a heating issue

Customer is complaining of no/very little heat coming from vents when setting in middle at 22. At both sides (drivers and passenger side)
I can confirm this. Basically its blowing near enough cold air when set at 22.
Customer has had the car a while and recons its not what it used to be.

No faults logged at all. In any system.

I have checked the coding of the heating unit. All seems coded OK

I have checked the live date of the temp control flaps again they seem to be working as they should
Only thing I noticed is when set at 22 (in the middle) the readings are lower than 50%, they reading 40% both pretty much the same.

I have also checked the Evaporator temp sensor and it is reading as expected..

I did basic settings on all the motors via VCDS and they all working as they should.

Wondering if anyone can help with this at all..

Thanks

How about the vent temperatures, the interior temperature, and the sun intensity values? If one or more of those is wonky, I could see this affecting what the system does.

And then of course there's the question whether hot water is reaching and freely flowing through the heater core.

Can you do the Adapt flap end stops in Basic Settings?

[Select]
[08 - Heating/Air Conditioning]
[Basic Settings - 04]

Select "Adapt flap end stops" from the drop-down list
[Go!]
The basic setting takes approximately 20 seconds.
Finished Correctly should be displayed
[Stop]
[Done, Go Back]


If you change the temp from lowest to highest quickly, can you hear the airflow change in the vent system?

Along the lines with the 2 previous posts, do you get A LOT of heat when temp is set at max? In other words, is it just a "calibration" issue or is the heater not working?

Not sure in UK, but in USA ppl use wrong coolant all the time (universal is not really universal :( ), and that clogs the heater core.
