My 2015 battery lasted for 3.5 years. Finally died once I moved to the Oven State (Arizona). I got a bigger replacement and coding took 2 mins.

The stock battery in my '16 GTI is 3.5 years old here in Atlanta, never garaged so it's exposed the elements year 'round. I"ll probably move to a group 48 when it gives up, the TDI will definitely get upgraded to to the larger battery when it's time comes.

They don't last long in Phoenix.

When I lived in Chandler, I'd get 1-2 years out of my VW batteries, and 4-5 out of my BMW batteries, presumably because they're all trunk-mounted and away from engine heat.
The thing to do in metro Phoenix is get a replacement that has a full replacement warranty for 3-4 years, with no proration. My GF got several free replacements in her TDI this way. Metro Phoenix is where car batteries go to DIE!

I just changed my battery with basically a like for like from Advance Auto, and changed the serial code as per forum wisdom as it only takes 2 minutes with obd11. Wholly unconvinced it does anything at all though on a non stop/start car withoit the terminal module...charging systems have been self regulating for aons, I don't believe after all this time and tech advances cars now need telling a new battery is in place.
Maybe if your battery size is bigger, or you change type to AGM I guess.

Well the battery I put in back in 2019 died already. It looks like it's leaking, I never got it coded. I wonder if it was overcharging itself and died a premature death? I'm going to put a new one in, can you do the coding with OBDeleven?
Really should get it coded. When I replaced mine with a 48 AGM from O’Rileys the “old” coding was for a BCM battery.

Anyone have specific instructions for coding a battery? I’m going to mark this for future reference.

Did some more reading and seeing that unless you have start/stop functionality you don't need to re-code.
Well you might want to check what your battery is currently coded to ensure you have the correct code for your current battery. I "think" my battery from the dealership was a BCM; when I put in the new battery I bought a AGM, and only found out the coding because I went to change it. Just sayin.
Give StealthGTI's youtube a like not me!

Check to see whether there's a battery control module on the negative terminal.

There is not, it's just a normal negative cable.
The current battery adaptation is "Wet" and manufacturer is "JCB" the capacity is "60AH". The battery i have in there and that I replaced is an Interstate 70AH AGM (Fleece). Do I need to buy the Pro subscription to change it or does it not matter?
