This is a European car with service intervals built into the system in terms of time, miles and hours running, you can see the counters in the screen options. We don't do Jiffi-Lube in Europe; vehicles under warranty go to a dealer. As the vehicle has a 5 year warranty, it is worth some effort to keep it valid.
Now, theoretically, anyone should be able to do the servicing work, so long as they used the OEM parts and the correct oils and kept the receipts. As the service manual is not currently available to any retail customer or non-Ineos dealer, I suspect you, (and I), have a problem.
At the moment only the dealers can reset the service counters; a consequence of Ineos writing their own software. You can change your own oil, making sure you use the right oil and filters, keeping the receipts, but you will just have to put up with the erroneous service reminders, (and they can get a bit insistent), until you visit a dealer. It does not brick the vehicle, (unlike HP and Brother printers - use their service contract, don't ever dare to cancel/not pay up).
The manual and access to a service tool was part of the original marketing but the open-source utopia crashed into Intellectual Property issues, non-authorised release of technical details to unqualified persons, rumoured dealer greed, real politik and "not invented here"; it was part of the sales contract to me, so I'll be going down the UK Consumer Goods, 'fit for purpose, goods as advertised" route eventually. What the USA equivalent is, I don't know, I sorry. I do know that Right to Repair does not cover it; that just means that non-Ineos dealers should be able to get access to data at some point in the future.
