vs
Battery OEM BMW or OEM Audi
But during the ownership i found it really reliable, the only things i needed fixing were: battery (it was the original one over 7 years old), tyres and brake discs/pads (consumables on any car) and the regular oil/filter services.
Pros: really reliable
Vehicle:
BMW X1
The battery is most likely to outlive the rest of the car. No need to worry. If the car has enough range for your daily need, then keeping it will be the best option.
Pros: battery likely to outlive car
Vehicle:
BMW
If you really want to buy this one (I find the price quite high, but I don’t know the specific market in Norway), buy an OBD adapter and EVScanner app on iOS with the BMW module. You can check the SOH of the battery and the general state of it as the replacement could be quite costly (around 1500 per module and you could have to replace up to the six if all fail or the BMS). I’d guess the SOH would be at best around 85%, maybe less. The engine itself is pretty reliable as it’s a detuned B48 from the 330i. Go to the infotainment and check the stats from factory and the percentage of eDrive kilometers (full electric) compared to the total kilometers, it would give you an idea of how the car was used and how much charging it got. This specific model of car is great to drive if you can charge everyday and you drive mainly short distances. I do around 80 km daily, almost all highway and my average consumption on those drives is 3.5 liters and 10 kWh/100, so it’s about 2/3 of the cost of my previous car, while beeing a lot better to drive. I’d still buy a 320 or 330i instead because there will be less things that could fail and I would probably not want to get such a high mileage PHEV without knowing how it’s been previously used. Source: I have a 330e from 2021 with 112k km and the SOH of the battery is 90% with around 1400 cycles. Average consumption since factory is 4.9 l/100 km and about half of the distance have been made fully electric.
Pros: great to drive, good fuel economy
Cons: high price, costly battery replacement
Vehicle:
BMW
Mileage: 112000 km
I took a drive in my i4 a couple of weeks ago that estimated I'd get home with 4% battery. Guess what I rolled into the garage with..... 4% battery. These modern systems are pretty damn accurate.
Pros: pretty damn accurate
Vehicle:
BMW
I just replaced both batteries in my 2018 740iX. Was original battery (build date was Aug 2017) so actually lasted 8 years which was surprising given other problems I had with the car!
Pros: lasted 8 years, surprising longevity
Vehicle:
BMW
I still have the original BMW battery on my 2005 e46 325i , I used a battery tester on it and still say it’s good
Pros: long lasting, still good
Vehicle:
BMW
The only issue we’ve had with it is recently a bunch of warning lights started popping up randomly but all at the same time. I assumed it was a wiring issue or something since none of the systems it said were disabled actually were. Dealership couldnt replicate it so it took a couple weeks of bringing it back and forth every time it happened before they were able to see anything on their end. Replaced the battery and it’s been fine since.
Pros: fine since replacement
Cons: warning lights popping up
Vehicle:
BMW
BMW 3 series in the right rear panel. The location is ok, but the box is just enough to slip in a group 49, and there is an air vent hose on the forward side, and a clamp on the rear bottom that is impossible to reach with anything but little elf hands. Then there's also the starter cable, battery management and regular wires running in the same area, all hopelessly in the way..
Pros: location is ok
Cons: box is small
Vehicle:
BMW
Spouse has a 2021 etron, (some issues, inc battery recall), I had a 2022 etron with many issues which prompted my change to a 2025 SQ6. I’ve written to Audi Canada so many times regarding the etron issues with no resolution on any of them. I like the SQ6 but this will be my last Audi - worst experience I’ve ever had with any vehicle and manufacturer.
Cons: worst experience
Vehicle:
Audi
It is a great car to drive.\n\nThe battery range is very, very poor. On a cold day the range may be in the 120 range. It is exp naive to maintain as most parts on it are coded which means Audi dealer only
Pros: great car to drive
Cons: battery range very poor
Vehicle:
Audi
