    Steering Wheel Upgrade

    I have not done it, but a few people have. The main thing I want to do is put a heated one on.

    Climate Control Green LEDs failing or flickering repair

    I'm not convinced this issue is with failed LED components, but more likely with solder joints failing. LEDs rarely just quit working unless overdriven. The ones on my car come and go at random, which seems to support the poor connection theory. So yes, replacing the LEDs likely *WILL* fix the...

    Dead iDrive Controller

    Symptoms: No lights. No response from the head unit to the center console controller. Head unit responds to all other inputs from the steering wheel and dash. Checked / tried: Fuses 12V/5V at the connector Disconnect/isolated RoadTop Unit Reset miscellaneous unrelated codes Coded to force a...

    Battery replacement/upgrade service in North America?

    The BMS doesn't know the difference if voltages and wiring configurations are the same.

    BMW Connected drive 3G to 4G?

    Wondering if anybody has installed the Open Vehicle Monitoring System yet? I don't care about cell service with it, but I really want climate control operation!

    I had a 3G to 4G TCU upgrade to prove a point.

    AT&T has not shutdown the service yet. That happens on the 22nd. (Tomorrow.)

    Tire pressure and miles per Kwh

    Most likely, they figured out people were getting blowouts from bottoming out the tire on potholes, and they wanted the extra 2-3% more range that extra pressure provides

    Rear-Fog Switch Retrofit (U.S. i3s)

    Anybody tried the ECS part yet?

    Thoughts on cutting off 100% to account for lost capacity?

    I recently learned of the Deep OBD app for Android. It shows real time battery voltage and charge level. Fully charged, mine was displaying right around 390V and 80% charge via the OBD data, but showed full capacity on my dash. Last time I checked kappa, it was something like 18.1kW, which is...

    Different wheels on i3?

    There are numerous custom forged options available that will fit with sizing from 5'5" wide on up, but none of them are cheap. BC Racing seems to have the best deal going on their wheels at about $700 a pop. You can find less expensive options in a 19"x7.5" wheel with appropriate spacers...

    No Anti-Sway / Stabilizer Bar in the rear of the i3

    If you don't want to go stiffer, you can always go softer. If you soften the front anti-sway bar, you achieve the same balancing effect as going stiffer in the rear. Softening it would also obviously not increase stress on mounting points.

    Anyone have their A/C compressor replaced after 15Y/150K warranty ?

    Yep, this is clearly spelled out in the vehicle warranty for people who bother to read the entire thing. The 15y/150m spec appears only in the emission controls section and applies only in that context of that section.

    Tire pressure and miles per Kwh

    I recently conducted some coast down tests on my i3. And contrary to what I stated before, roller mode is not necessary, as neutral works just as well. That said, what I noted was that the recommended pressures for the i3 are a little on the soft side and are soft enough to hurt rolling...

    Lowering springs for the i3?

    Yes. (Sort of). In general terms, because even relatively flat bottomed cars like the i3 are riddled with parts that generate turbulence, anything you can do to reduce airflow underneath without increasing frontal area will improve aerodynamics and reduce drag. How much? No clue there.

    Tire pressure and miles per Kwh

    The easiest way to measure the difference in such a change is with 'coast-down' testing. Using the same piece of road with no traffic, repeated runs are timed from a set speed down to a predetermined low speed while coasting. The i3 would need to be placed in roller mode to do this, but...

    Why are 'loud cars' so tempting?

    Yes, 'shaming' is the proper term. "No, officer. I was not drag racing. I was shaming!" :D :D :D

    My BMW i3 Saved My Life

    The ACC is merely an accident mitigation system, not avoidance obviously. I don't like the way it responds to normal conditions, but I use it just in case I do get distracted at the wrong moment. Glad it worked for that at least! Sadly Aaron, this is likely going to be 100% against you on...

    [RangeAnxiety] Survey research

    I think most everything up to the final scenario questions are really just demographic baselines. My commute to work is about 4 miles, so I answered 'no' to every scenario with my 22Ah i3. On the daily use, the only reason I could have for range anxiety is exactly like neglecting to put fuel in...

    We have met the enemy and he is us

    I think the current public charger system will always be problematic with this stuff without making changes. Many are in unsecured locations where they can be vandalized, blocked, or abused. They are installed like payphones in that sense, relying on a public honor system to not destroy them...

    BMW I3 to a Subaru Sti

    Proper winter tires for the STi are not going to be cheap. Get Hakkapellitas or stay home. ;) Seriously though, for winter driving, they are pretty awesome, but I did make the mistake of staying stock width when I put studded snow tires on my 2005. That car ripped through ice faster than...
