Alohart;- I had been assuming the BMS buffers which lock away 15% of the battery (assumed 7.5% at top and bottom) was a factor. The figures seemed too coincidental otherwise. The battery was at 100% as reported by the car. I'm more than happy with the battery health, and not particularly worried...

You don't need a scanner to do that, as I'm sure any number of YouTube videos will show you. If your battery is 75% or less then you can go through a menu choice and force the HSOC option to start the Rex. At the last press before you enable that option, press and hold one of your eight...

If your rear lights are LED already, then you should be able to swap front lamps over without any problems whatsoever. It was a straight swap for me, without any flasher problems. Headlamps too, and two out of three front lamps accessed behind a cover in the front wheel wells.

The battery kappa max figure, via hidden menus, sounds like it does a similar function. On the i3 it really only is a 'guide' though, useful to spot trends perhaps but not absolutes. On mine it varies, again seasonally, from 27.2 to around 28.

Alohart/eNate, Thanks for that info and the explanations. Seems to show my car is in pretty good shape battery wise. In the 3.5 years I've had it I've not seen any appreciable drop in range, apart from the usual seasonal variations. For me that means 100-130 miles and 60 to 100 on the rex. Not...

After a year or so of only charging to 90% or so, and after all the articles/opinions I've read, I recently started charging to 100% each time again. BMW (in my 94Ahr rex at least) only let you use around 85% of the battery capacity anyway, see the picture for SOC while the car tells me I'm at...

Approaching 8 years old, and this is my HV battery health status after the most recent full charge. If you look at the figures, the SOC and SOH figures are very close to each other. Does that suggest that the battery is in near full health? Or does dividing battery capacity by rated capacity...

@James:- I think you're rather missing a distinction here. The i3 rex may have a built in generator, but it is no way part of the 'drive train' it exists solely to generate power to the battery. The cars drivetrain is pure electric, this is not the same as a PHEV.

BMW is for me one of the cheapest manufacturer map updates I've found, in that my i3 updates via a USB stick and is just £50 for a whole year of updates, which can be up to four in one year. My service agreement also included two updates in four years. You just need a large empty 32Gb stick, and...

The distinction is that your car was registered after March 2017, because that's when the vehicle tax rules changed away from emissions and towards vehicle value. My i3rex '66 plate pays zero tax. Is it the case that yours was 2018, and valued at more than £40,000 as an on-the-road price Inc any...

Mine has not logged charge received last couple of times, but does slowly update to say fully charged at xx:xx hrs. Also don't seem to get 'notifications' as often as I used to, re charging etc, and what time car predicts itself as full.

My screen before it was replaced by dealer under warranty, which I subsequently replaced (once out of warranty) with a 10.25" unit.

Apparently fairly common on older model screens. My '66 plate i3 (2017 model) with a 6.6" screen developed this problem by itself. It grew from a tiny splodge a quarter inch across, to bigger than a 50p piece. My second hand car warranty eventually replaced it for free with a BMW item, claiming...

That would be my thought also, once my battery warranty is expired.

I contacted Lion Smart once years ago when that test i3 made headlines. They were quite clear that their tech would not be made commercially available to i3 car owners, and that their test i3 car was a 'proof of concept' demonstrator. They were (at that time) aiming solely at public vehicles...

In the UK it's not unusual for me to gain back 2-3% on downward hills, all while keeping slight pressure on the pedal to maintain a safe speed. Balance that with the thought if you reverse your journey you're still using power.

82,000 miles on my '66 plate 94Ahr Rex, and no appreciable sign of battery range degradation in the three years I've owned it. I still get 100-135miles winter to summer. Only charged up to 90% at home unless I need the maximum range, and rarely fast charged. Battery kappa max still shows...

Also, GPS location within the vehicle must be on, for the tariff/app scheduling to work at all. I too see random schedule times reported back to my bmw app, and also the occaisional 'could not control your vehicle'. These I just ignore, as the schedule sets uniquely each time, and car charges...

JamesinLondon. You're so right, I'll be keeping mine for the forseeable..😎
