I wonder if it would be possible to add an aux heater in the hvac similar to what the MK5s had. This would aid to defrost windows faster and get cabin heat faster in the winter. Thoughts?
Whats it called in VCDS?I think it does?
I disabled it in vcds and it makes a huge difference.
Someone mentioned that's why our cars have a decent alternator is because of the aux heating grid...
Coolant has to be cool, heat maxed, and assuming a certain outdoor temp...
Conditions right i do hear a relay, lights dim, and ecm touches the rpm a bit, probably to help alternator move air over itself.

It could be a dual element. But either way i doubt the mk7s have them guess one of us should look and see...2010 mk5 heater/relay had 100amp I think (100x12 = 1200w) you could also hear the chunky relay cycling at idle. Our '15 Passat has no audible relay clicking.
Also I have no idea why the would split the relay as 2x40A, that is just backwards.
according to the VIN scan, my vcds scan, my 2015 Cdn Golf TDI did not come with the heater.... I am contemplating getting a used one, and installing it for next winter...Has it been confirmed that US/Canada mk7s do not have a aux heater?

I'm now convinced mine does. Trendline GSW.Has it been confirmed that US/Canada mk7s do not have a aux heater?
My 2015 Golf S has the heater. Finally confirmed (with my eyes) 18 months after the last activity in this thread, haha. Anyway, previously I mentioned that my Golf has the following PR Codes, of interest here...They do not have them, at least the cars designated for the USA. It was deemed unnecessary with the different cooling system architecture. Essentially a micro circuit around the cylinder head to help bring the water temp up as quickly as possible for cabin heat. I specifically remember checking for this when I took delivery of a new 2015 Golf TDI in May 2015.
Edit: Going back a few years, I found this from a previous thread on the topic. This was from the build sheet on my Mk7 Golf TDI:
7E0: W/o heat accumulator/auxiliary heating
Also of note, 9M0: Without auxiliary/parking heater
