Mind you, Audi are no better.
Our most recent car is just new enough to have a digital service.
As it's the first car we've had to have this option (and is
second hand) I didn't think anything of it until we took it to the independent mentioned above who said "where's your service book?"
As we couldn't find it, I called the garage we bought it from who said "it's digital".
We'd already paid for the service, so I emailed Audi customer services to ask about getting the new service added to the car's digital version.
Heard nothing for a few days, so then called them and was told the independent COULD register on a site called ERwin and upload the details.
I then got an email back from Audi which said there was NO WAY that an independent could upload a service to the digital schedule and the car would have to come in to Audi in order to keep the record intact.
At which point I told them about my phone call and they responded with NO SHAME that 'Oh yeah, you can also do that'.
Same person. No apology. No 'sorry we made a mistake' or 'sorry we told you an outright lie'
In the end, it was hassle trying to get the independent to register to be able to upload the info, so I bought a paper service book from Audi, and got them to stamp that.
It annoys me because I thought the whole point of the new digital service schedules was so that it was harder to fake a car's history, but I naiively assumed it would be some sort of centralised record. Like MOTs or insurance. But it seems each manufacturer is like this.
