Hello, I have a 2020 Jetta- manual says its a gli united states. My Auto turn or/start stopped and has an error. Could this be a fuse?
Also my #18 fuse is missing, is this supposed to be empty?
SOS Emergency call feature started not working about 1 week or so ago. is there a quick fix like a reset. I’ve tripped the batter but that didn’t work I understand they have a back up power supply . I just have not been able to find it . or do I have to go to the dealership and wait an eternity lol.
Is there a list for the empty slots? if they are hot all the time or just when the car is on?
Hi,
My Jetta S 2019 blind spot light blinks properly, but, Volkswagon doesn’t have the facility of SOUND ALARM.
I’ve purchased aftermarket alarm that blinks and gives a sound, I need to know where are the fuses/wires of the side mirror orange blinking lights so that I can attach the Negative/Positive points of the alarms which I’ve purchased.
I’ll really appreciate it if I can get the location/S.
Thanks,
Sayyed Khalid.
My South African Jetta 7.2013 has only one 40A fuse, not 3, as your diagram.
That 40A fuse (10th from right in top row) is not the one for “air fan control module” I am looking for.
I find it incomprehensible that Volkswagen does not include fuse assignment diagrams in its manual.
