Hi, I have 2018 e-Golf. I'm trying to figure out the preheating in various scenarios. I can get it working while not plugged in but I'm not sure it's working properly. I set temp in the settings to Max, but it warms up the car with only a small trickle of heated air through the front windshield vent. No air comes through main vents like I'd expect.

Is this correct behavior? It does not heat like when I'm driving the car.

Thanks


Hi Tom, how did you setup the pre-heat? My co-worker has a 2018 and being an EV nerd I've been helping her understand its features. I've read the manual but its typical german confusing. (i'm in Canada too)

It's buried in the car stats menu. To be exact it's under Menu/Vehicle/e-Manager. There are three default entries, but you can add more if required. The temp, time and other settings are further buried and not necessarily obvious. Note though that only one is active, so it's a frustrating PIA when moving from local to local and having to remember that "at this place I want it on at this time, so select the third option".

I've been able to get the pre-heat working when plugged in, and it's very nice. From what I've seen from the program, the fan can be heard, even from outside the vehicle. The cabin is warm (though 22*C...?) but seat heaters don't work. The inside of the windshield is clear and given the fact the range worked out by the comp shows no significant loss compared to when I get in it cold (example: ~125km pre-heat compared to ~94km from dead cold), I'm assuming the battery warmer is working as well. (pet peeve -no feedback as to state of battery warmer, or for that matter the heated windshield).

As you've probably experienced, the car won't start when plugged in, and it has a fit if you leave with the keys. So, my question is, does anybody know if, when still plugged in, the battery warmer or windshield heat up/turn on if you go "old school", like with an ICE, and run out in your slippers and "start" the car 15mins before leaving?

I've tried it a couple of times at -15*C when the car is still plugged in, but stupidly didn't verify range before turning everything on. Will try again but it's a very frustratingly subjective result when trying to measure the warm-up state with simple range stats provided by the on-board pc.

Does anybody have experienced with this?
Jon.

Jon, I'm pretty sure the heating system will only run when the car is turned on and ready to drive. Since you can't turn on the car if it's plugged in, you can't do an old school warmup while plugged in - you have to do it with preconditioning on timer. I think you can do old school warmup with car unplugged though. If you haven't driven since starting up, you don't get the beeping and auto 30 second shutdown. You could technically start it up, leave and let it warm up. I wouldn't though because it heats up so fast anyway compared to ice car.

Thanks Tom2018egolf. I think you are correct. I've come to the same conclusion after several different attempts. I guess I can still do the old school warm-up by going out 30mins before leaving and turn on the timer. A little clunky, but a happy family is worth the effort.

On a side note, I ran across this post from a fellow Ottawa (Canada) driver. I don't know if this has already been posted on this forum or not, but it has good detail and has a very useful, if anecdotal, example of what to expect here in this part of the country.
