    What's Better: Bridgestone Blizzak LM500 OR Nokian WR D4 ?

    I have the Blizzak on my i3, and Nokian R3 on my GT. While not the Nokian you indicate, the R3 is available as well. The R3 is a winter 'only' tire, while the WR series is a winter tire that works on warm situations, too, as long as you don't say live in the desert where it regularly gets...

    Engine check light

    A defective pump might pull more current than it should, but typically, that would blow the fuse before it would pit the relay. An intermittent, though, if that caused the relay to open/close frequently could do that. When in the military, on the relay coil, they always seemed to install a...

    Auto-dimming Wing Mirrors Useful??

    I like the effect, as it can be quite a distraction when someone behind you has lights somewhat maladjusted, or sits on your bumper at a light. It can mess with your night vision. Most people do not adjust their mirrors properly. The best technique I've found is to lean as far as you can to...

    best sunshade?

    I bought the BMW climate cover shortly after I bought my i3 way back when...it does not take much time to install it and it does a much better job of keeping the interior cooler in direct sun since it reflects most of the heat before it gets inside. An internal sunshade will let the glass get...

    Can I charge my i3 120Ah at a Tesla CCS charge station?

    The original CCS standard did not allow the charge speed that Tesla wanted, so IMHO, Tesla decided to build their own. THat also kept the 'riff raff' from trying to tie up the charging network Tesla spent a lot of money building. There was talk about letting others utilize their standard and...

    Range and warm weather

    95% of all my driving can be done on my 2014 i3 BEV. Should I need to go further, or carry more, I have an ICE that gets used infrequently. But, to simplify things a bit, I have an X5 45e on order, and while it certainly won't be as easy to park! it will let me go a long time in between...

    Scratched Hood...

    FWIW, nobody likes to see damage to their vehicles...some take it as inevitable, some get more annoyed. Whatever, it can be repaired, and might be cheap and easy depending on how deep.

    Scratched Hood...

    The other side panels on the i3 are painted...I'm not positive if the hood is, but I think it is. It might buff out, depending on how deep it is. Not all BMW dealerships are certified in i3 bodywork, but one of them can tell you what's required to repair the scratch. Unlike a metal panel, a...

    Range and warm weather

    During use, the battery warms itself. LiON batteries do lose capacity when cold, but not as much as say lead acid ones, so there's a tradeoff as to what temp to warm them is enough without wasting a lot of energy. If they get too hot during use, then, more energy is required to run the cooling...

    Speed sensor...

    That difference is nearly 3%...normally, they expect the tire sizes to be within 2%, so you may have some logic issues for the traction control, not counting the speedometer and odometer readings.

    i3 LED Headlights

    When you first turn them on, you will see the beam move up/down. I don't remember if they bend for turns or not, so there is at least some adaption to them.

    Speed sensor...

    I don't know on the i3 how it determines road speed, but it does use the wheel rotation sensors to check for uneven rotation rates to detect what it determines to be slippage. I do know that there's a computer in the loop, as BMW has chosen to increase the indicated speed by 2-mph across the...

    Car to car charging

    BMW demonstrated a prototype home power storage unit using battery pack(s) from decommissioned i3s. This is not from a working vehicle, but after a battery pack was removed, giving it a second life. So, there is a commercial use for the battery packs, even when they no longer meet the...

    New owner long distance charging concerns

    My bad...confusing amphr with Kwhr...still, I prefer to get in and drive until I'm ready, not being limited by the vehicle. Overall comfort is a personal thing, and while I don't have any issue running around in my i3, when I have driven to the point where I needed to recharge, I was ready for...

    Range Vs mileage Vs charging speed?

    Recharge cycles tend to be the limiting factor, so with a smaller capacity battery, to go the same number of miles, you'll have more cycles, thus, more degradation than you would with a larger battery pack. A cycle is considered 100-0-100%. But 100-90-100% times 10 is the same degradation as...

    Has anyone tried the 'electrified' app'?

    FWIW, many BMW vehicles seem to not appreciate something left in the OBD port once you lock the car. On some, it can trigger the alarm system, so general use of something there might be an issue. WOrks fine for diagnostics, but not long-term use. So while it may work, it may not.

    Where to find Level 2 home charger ratings/reviews?

    I have a Clipper Creek device that has been serving me well for over 5-years now. Basically, they are pretty simple devices. The actual battery charging is done and controlled in the car, so the EVSE is basically a smart power cord. A good portion of the cost is in the cable and plug. A bit...

    New owner long distance charging concerns

    From what I've read, many of the UK utility companies will subsidise installation of an EVSE, so you will want to look into that. If you're done taking a long trip, it will take many hours to recharge your batteries...better in the UK with 220vac than in the US with our 120 on the plug-in...

    Activating Carplay on 2018+ i3

    BMW makes running changes throughout the year, so models the same year may have different hardware and potential features.

    REx Distance

    If your normal day has you sitting in the vehicle with the a/c running while you do paperwork, your efficiency in AZ where it could be 115 in the shade, could be problematic on a typical EV...it's not just the miles you put on, it's the time the thing is functioning. Personally, I don't mind at...
