Starts fine even in -4F weather. Will probably swap it this year with another OE battery as oddly i have better luck with OE batteries and they tend to be cheaper than Autozone/Orielys/Advanced.
2017 got a new battery in 2023 before winter, didn't have a no start issue but figured it was time. Went with a dealer battery, was only $138ish for the 72ah upgrade and replaced it in their parking lot to get the core charge back.
You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.
Update: it was just the battery, everything works fine after replacement and coding/adaptation. No error codes. Thanks everyone
I use Deka sealed batteries so less offgassing messing up terminals.
I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.
I’ve had my id3 5 years now and had very few problems with the car or charging. I’ll get maybe 180 miles on the motorway but close to 240 miles cross country. Manchester to Sheffield to Nottingham and back to Manchester left me with around 50 miles range, but I can’t get from Manchester to London, or Manchester to Glasgow without charging.
I just preemptively changed my 2007 VW golf battery at 120k...I probably could have gone farther but every now and again I would get a weird code that likely was voltage relative.
2022 ID.4 in Canada. Have had two replaced. Luckily when it happened it was in my driveway for all three times. Hooked up a charger to the 12v for a few hours and it started like nothing was wrong.
The battery VW uses in the ID.4 is trash. I had it replaced under warranty in my 2021 after about 2 years when my car died in the garage and I had to get assistance. The tow truck driver got it going with a jump starter. It\u2019s now just out of warranty in year 4 and I get the \u201cLow 12V\u201d warning on cold days.
