Your mileage went from VW->telematics vendor->broker->carfax, thats the chain it usually follows. The fuse stops it but the real issue is the owner is the only one without the record.
You could probably find some interesting info if you send out some privacy requests through the chain. LexisNexis and Verisk are consumer reporting agencies, so they have to provide you a disclosure on request. Start there.
So I first read this comment and thought is looked like AI and thought I’d give the benefit of the doubt. Then I saw this where there is no doubt: https://news.ycombinator.com/item?id=49687774
I thought, I wonder if it’s the same guy? Sure enough.
Stop it.
Is there usually a fuse that just turns off the telemetry? I would be surprised if that is the case. I could see the design being "if you turn this fuse off to turn off telemetry, you'll also lose these functions: ..." and if they did it "right" they'd make the car non-functional.
My car is from 2011 and I do wonder if there is any telemetry in it.
