Although BMW upgraded the drive motor bearings in 2018, the root problem remains... they are sealed bearings that are too small, and have no lube recirculation for filtering or cooling... resulting in a rather limited lifetime. I had to replace my 2015 drive motor at 95k miles. The problem...

Very old thread, but I've recently read that the first Gen i3 already have the codes in the computers for the 94Ah battery... and that it's a simple "retrofit" matter... like enabling (retrofitting) the 10" screen in a car equipped with the small screen. I bought a 94Ah battery from a salvage...

Have you had any issues following the bearing replacements? How were you able to get the rotor re-installed exactly in-sync with the resolver - so that the inverter still had the proper stator/rotor timing ?

Did you ever move forward with this? I already have a 94Ah pack from a similar situation, no airbags deployed. My 2015 BEV is undergoing drive motor and transmission swap now, and after that I'm hoping, hoping to see what's involved in the battery swap... other than the obvious discharge and...

How certain are you on the x3 bolts... 07-11-9-907-560 BMW shows this as a long sway bar link bolt "Hex Bolt 071000"

SolidJRock, can you give any detail on setting up the computer for the software, and what version of the software is needed? What version of Windows? Drive space needed? RAM requirements? Any specific OBD hardware needed, or just a generic ethernet OBD cable? Is ICOM needed? (I don't even...

It's specifically placed before the expansion valves because that's the tiny orifice that can get plugged by the debris...

Disassembling a large PM motor like this is a near impossibility - without very specialized equipment. The highly-magnetic rotor will grab onto the stator, and pulling them apart without damage would take a hydraulic machine with extremely strong "centering". Re-assembling would be even...

What was the outcome? Did they replace the $6,000 EME, and then say it also needed the 12 volt battery?

I know, I've heard it before... just fix the 2015, sell it and buy a 2018... and maybe that's the best solution, but convincing my wife to buy another i3 that has definitely not been the "ideal EV" (after this expensive failure) won't be easy. I keep hearing talk about getting a Model 3...

Haven't yet pulled the trigger on the complete 2018 drive assembly... after reading that the 2017+ model year EME - had the charging module removed and put in the KLE. This also changed the LIM charge controller and of course the KLE itself, meaning I would have to change all of those to use a...

This will certainly be a very technical question for someone out there who has serious understanding of the i3 communications traffic and logic. My 2015 BEV has the Drive Motor Bad Bearing issue that's plaguing more and more early / high-mile i3's. BMW refused to offer any more than 15%...

What became of your situation? Did BMW help? These days I read of an increasing number of this failure, and many are able to get a free motor from BMW Corporate, customer pays for installation.

I'll soon be finding out, that's what I bought for my replacement... 2018 complete electric drive assembly, 24k miles, with EME... from a Rex S, but that doesn't change anything about the electric drive motor.

I just saw this listed a few days ago in either a BMW notification list of required software updates, or maybe an NHTSA list. Ask BMW about it. I just found this... seems to say the tailgate/lift gate can be codes to. open only after vehicle is unlocked...

Kind of defeats the goal of buying an EV to save money that we were spending on gas (petrol).

The 2018+ uses a tapered roller bearing, very unlikely it's the same physical dimensions... the "taper" means the outer race diameter will be larger to accommodate the taper angle...

Design flaw - they used the wrong bearing type in pre-2018 model years... so replacing the bearing isn't going to be a long-term "fix", but a band-aid.

This problem is on the rise as these cars reach higher mileage. My 2015 BEV (Tera, w/every option) started this motor bearing whine at about 94k miles. The dealership (BMW South Kansas City) tried to get me to trade it in for $2500... what an insult. They estimated over $16k for the repair...

Anybody have any updates on this issue? Mine just got all noisy... https://youtu.be/yl8CELCGf_M
