Battery OEM Volkswagen or OEM Mercedes

My 2014 jetta TDI does the exact same thing as in your video when the battery is dying. I've had the car now for 6 years and it's happened 3 times. If the alternator checks out fine, then I would attempt a new battery.

This just happened to me last month on my 2017 C43 on the OEM battery. I guess five years is typical on these newer MB.

Change it when it can no longer meat a battery test to spec, which has good margin before it starts causing issues, like freaked out ECU or hard starting.

OEM VW Battery lasted 7/8 years, despite me nuking it by foolishly leaving my lights on. Sad day.

I replaced the battery of my 18 SE this year and did not code the battery. I replaced it with an OEM one from VW’s parts department and had no issues

the only time it failed me was when the battery died after 100k miles.

On a Jetta, it will leave you stranded, and it being a VW, the symptoms will be nothing like a dead battery, most likely.

Mine crapped out at 34 months. I bought a new one from VW since they had a 5-year warranty on it and it's still going...

I've got an essentially new Golf R only about 3 months old and I think my battery is no good. I keep it connected to a battery tender as I dont'drive it often. Even after a week of being connected it never reaches full charge. Also, After I discomnect I put a quick load on it by turning on the lights in order to remove the surface charge from the battery tendder. Prior to putting the load on and just after disconnecting the battery tender the rading is 12.8Votls. After putting the load on by turning on the lights for a minute the voltage reading then drops to 12.28 which seems awfully load. I'm assuming my battery is no good.

I’ve had it 3.5 years and it just started doing the “Stop Vehicle Leave Engine Running” thing about a month ago.
