    2014 i3 REX with 11.7 Batt Kappa Max

    BMW may well have improved their act but I wonder whether also the simple fact of the larger battery needing, in effect, less cycles for the same amount of driving is a factor?

    DIY HV Battery upgrade

    Just curious, (and too lazy to read through all threads!) Will an upgrade from a 94 REX to a 120 REX be any more complicated than the other upgrades that you have been doing? We have a 2018 94 REX showing no sign of battery degradation at nearly 60,000 miles, so this is not urgent, but I'd like...

    Potential Buyer with a few simple questions :)

    ... Just like us: in the UK, home charge easy, away charge seldom necessary. Whereabouts are you? We are near Stroud, Glos.

    Potential Buyer with a few simple questions :)

    There will be others along shortly I'm sure, with all the established wisdoms, so I thought I'd pitch in something specific ... bearing in mind that we're very happy with our one year and 12,000 mixed miles with a 2018 94ah REX ... If you're expecting to be regularly finding yourself in a car...

    Electric v petrol

    We're in the UK and nearly always charge overnight at home on "cheap rate" of 11p inc VAT per kWh ... The car is averaging 4.8m/kWh so we're currently on a best of 2.3p/mile ... rising to about 4p/mile as a result of occasional daytime charging at 25p inc VAT, and a handful of motorway charges...

    Grinding sound during regenerative breaking

    That'll be us! Eventually the noise, and the pulse that came up through the "throttle" pedal, was dramatically reduced by putting new non-rusty discs on ... We still have what I would call a "drone" most obvious around mid 60mph, which sometimes has the feel of good old road noise, sometimes...

    Timed charging of my I3

    Yes I'd heard that it is not a fixed point reading ... bit like the predicted range I guess? ... but it has never varied by that much. If I were to do a graph it would be a jagged line (+/- 0.4) with a steady upward trend starting after four months. Would be interesting to see how it matches to...

    Timed charging of my I3

    Who are you rebutting? I was giving my reasons for not worrying about charging to "100%". I know 100% isn't really 100% hence the inverted commas ... The buffer against what we used to call "boiling" the battery to 100 is built in. Ours is a 33kwh unit. It's considered full at 30kwh ... so we...

    EKR Custom Fit Leatherette seat covers

    Hi, this is interesting! I'm still glad I went with love2customised though ... I was given a LOT of choice on finishes, right down to stitching colour, and although fitting is not for the faint hearted, they really do, imho, hold true to the i3 look while doing their job of protecting the...

    Timed charging of my I3

    Some possibly useful notes arising from one year of using the BMW app: Here in the UK at present we have cheap rate from Midnight to 7am. Apart from a couple of motorway stops we have, in the last year, only ever charged from a 3 pin domestic socket (on its own circuit, with its own circuit...

    Front wheel bearing replacement

    Hi, did this sort out the booming? We have something along those lines, noticeably more in the mid to high 60's mph, so I'm wondering whether it's wheel bearings at all (engine mounts???) We have a 2018 94 REX by the way.

    Buying a 2018 REX i3s

    Understood ... That's what I meant by "bendy" numbers. Useful though as a small-ball-park health check when buying ... and to follow progress, if the same parameters (state of charge, time since charged, time since used, external temp) are used each time :-)

    Buying a 2018 REX i3s

    Hi, good to hear of yet another happy bunny! We've just had some warranty work done (one year on a BMW "approved used car" because we were getting judder on regen. Sounds as if it was a suspension strut damaged (pot hole) by PO. Rear tyres were worn unevenly (down to 0mm on external edges) so...

    Buying a 2018 REX i3s

    Once again, apologies for the late reply ... I need to set up my notifications properly! An update ... We bought the car four months ago at 42k miles, NOT 45k miles :-/ NOW we are at 45k miles and today's reading off a battery at 79% charge (so conservative?) is "28.6". Thought it might be...

    Buying a 2018 REX i3s

    Sorry, only just seen this... I must admit I had a moment when I cynically thought that the software could have been tweaked, as in when owners take their in-warranty battery in to show a 70% or less read out (warranty cut/in?) only to have the dealer "test" it and return it with a higher %...

    Buying a 2018 REX i3s

    Just been to see the car in question and the "hidden menu" gave a read out of 29.7 on a 33kwh battery after four years and 45,000 miles .... We went for it ....... :-0

    Buying a 2018 REX i3s

    Hi, and thanks for you reply ... Those numbers are surprising. I must have misunderstood! I thought the Batt Kap number started at around 90% of the nominal capacity, and was into "warranty territory" if it dropped below 70% ....... Do I need to go back to school?! EDIT: Ah! .... A 94ah will be...

    Buying a 2018 REX i3s

    ..... so what would be an ok read out for battery capacity on a 94ah after nearly 60,000 miles? Less than 88ah I guess, but by how much?!

    Buying a 2018 REX i3s

    Hi, and thank you :-) Yes, "Good old Blighty" I'm afraid :-/ It's this that I'm wondering about: "unless allowing it to remain at a very low charge level for a couple of months has accelerated degradation". ...and the fact that we did have a pretty HOT time of it for most of that time...

    Buying a 2018 REX i3s

    Hello! First post, and I have yet to buy an i3, so my questions will be about that for now ... I have seen a 2018 i3s REX with 57,000 on the clock, with one previous owner The positive side of me says this is a good sign ... not low miles and multiple owners suggesting issues, garage time...
