Recently i bought a VW e-golf 2015. Can't say a bad thing about it but, I observed that cabin heating is not working.
I mean, the AC is normally working and cooling and when I turn it on hi temp it is also blowing air but not warm at all. I've been at service on a diagnostic and they told me that they need to refill coolant in the AC because it is lacking. The AC indeed is cooling little bit weaker but really little bit.
Is this really can be the reason that the cabin heating does not work? Appreciate any help
