This was on a colleague's Volkswagen, 2017 Jetta. Had to help him with a jump start last week when his battery died, but he reported his air bag light was stuck on after replacing the battery. I told him it should go away after some drive cycles, but it stayed on for a week. Offered to scan the codes for him, and sure enough, dozens of DTCs for low system voltage for pretty much every system. The only code for the air bag was low voltage. I cleared them all for him and the light's off now. Is this something unique to VW that it can't clear on its own? Or does it just need a lots of drive cycles?
Air bag light after low battery

Make and model of your scanner, please.

Yes, but I've never seen one that leaves the air bag light on after the low battery has been replaced, hence my question.
I had eight DCTs, but nary a one that told me there was a problem with the battery voltage
Mine even said the right rear tail light was burned out.
And German cars are the worst

You should see what a Christmas lights party BMW throws with a low battery voltage.
Some of the early Honda Sensing equipped vehicles were especially crabby after a battery disconnect.
My 89' Regal wouldn't idle right for a week until the computer re-learned everything after a battery swap.
