2015 Passat Battery Replacement

No. The only difference is charge voltage to maximize its chemical lifespan. There is no safety risk.

I appreciate the response.

Has anyone used Ross-Tech VCDS in a 2015 Passat to change the car charging settings for an AGM battery?

If so would you provide some details please?

Don't go with And AGM battery, a lot of people think it's an upgrade, but it is not. With a standard alternator, which the 2015 Passat has, it will cause the battery to fail in. Not that long of time. I replace a lot of bad AGM batteries that are not very in these cars. Now the golf and the A3 for 2015 used an AGM battery and had the smart battery monitoring system and Lynn alternator.

Ok, copy. So an 'upgrade' for my 2015 Passat would be putting a size up H8 instead of H7:

Optional of course.

To fit an H8 you must physically cut the tray for it to fit the extra length.
A group 27 will fit and has 100cca more, but its 1" taller and terminals are opposite sides. There would be hood clearance and cable length issues.

Any battery could leave you stranded. I do have roadside assistance thru the insurance. Hope I never need it.

I never really feared battery troubles. Keep a pair of jumper cables with your spare tire and a smile on your face and people will boost you. All the times I needed a tow was when my tire would burst on a highway bridge or when my emissions were acting up.

Just leave the h7. It is really tight to fit an h8 in and the h7 is plenty of power.

Yep, the safety kit that came with the car from VW has jumper cables in it. I know that I have jumped many a battery for folks over the years. Put that karma in the bank for future use as needed.
