Pulling Fuse 19 and 20 did not restore myVW (Car-Net) and perhaps caused another issue

So we lost Car-net about a month ago. never tried to reset it as didn’t really use it much. In any case, tried pulling fuse 19 and leaving it out for at least 10 minutes, but 4G (and green light) never returned. Read that pulling 20 helped with some people as well, so tried that too, but same no result.

However, just after pulling both 19 and 20, car started getting an airbag error: on the cockpit diplay says error: airbag and the yellow airbag symbol stays on even after car started and driving.

Could either of these fuse pulls have caused that? or the combination of pulling both at the same time?

Bringing car in on Thursday to have dealer take a look. But wondering if anyone else has gotten the airbag error

Btw pulling fuses Willy Nilly is a really bad idea on this car. E.g. I’ve seen people also pull fuse 20 and then power on the car. This will result in a permanent airbag error, that can only be cleared by the dealer or by buying specialized hardware to manually clear the error yourself.

So a word of caution not to mess around with the fuses to much!

My dealer doesn’t even seem competent enough to clear the airbag error themselves and they want to replace some airbag monitoring computer to address this.

If they do clear it without doing that, if you could please let us know what they did— I’d love to pass it on to my dealer.

Did you call Car-Net?

When I went offline for multiple days I have them a call and my service was restored about two days later, no additional action on my part. This was after getting a full car reset and an uninstall/reinstall of the app.

I wasn’t hesitant about pulling fuse 20, but did read some about people on here having success with that as well. So after pulling fuse 19 and it not working, tried 20, but did it in combination with 19—meaning had both out at the same time. Perhaps that caused the airbag error. In any case learned my lesson. Car is at the dealer now, so we shall see. Having them address airbag first, but may have to bring it back for car-net issue, as they said they often like to keep the car for a day or two and didn’t have any loaner cars today.

With regard to calling car-net, last time we tried that was in December and they just told us to wait for a major update in early 2022. Not sure they ever released the major update from what i can tell except for re-branding car-net to myVW.

Will update if I get any news or insight when I get the car back

Want to update my last post to say I was hesitant to pull fuse 20. (not wasn’t hesitant)

«AWD or Nothing». May be getting same response you got as just got a call from the dealer that they haven’t solved the airbag issue yet, but think they may need to order a part. They want to explore more and will let me know at the end of the day. I told them to let technician know that I had pulled fuses 19 and 20 to see if that might help them solve an/or reset the airbag

But to those reading this, be careful about pulling fuse 20, and especially with pulling 19 and 20 at the same time

Airbag error can be relatively easy reset with the dealer tool or via a OBDeleven dongle.

If there are no hardware faults, the issue should be a 2 minute fix by the dealer. Might he not be trained on the ID.4?

When I mentioned the removal of the fuses, repair person said that helped him and he was able to just do a reset of the aribag. He’s now pretty sure it was just a trip fault and nothing serious. Said if it comes back, to bring car back in and will explore more. Turns out the delay or further investigation was into the car-net. We had had a problem getting the car-net connected when the dealer first delivered the car to us. Said that module appears to be bad and they ordered a new one. Said VW’s approach now is to just replace the module if car-net fails multiple times.

With regard to getting car-net going, the repair tech said that removing fuse 19 is similar to how they try to fix car-net connections, by cutting off power to the car-net module. He said they just do it through a battery disconnect rather than pulling fuses, but the approach is similar. He was very helpful. They think they will have a new module by Friday so hopefully we will be up and running with next day. I did pick up the car in the meantime and the airbag light and error is gone for now.
