  • 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.
    Sayyed Khalid.
