Same thing happened to me. I pay them to do a capacity test, which I know takes a while to do, they finish way too quick and say it is fine. They provided no certificate that showed how much capacity the battery had. I have the ISTA software and was able to run the test myself...ran it 3 times...

I have not had any trouble with my rex, but despite this, it has taken me awhile to trust that the rex will work when needed. I recommend you code it for "hold state of charge" That way, you will still have significant electric range if the rex doesn't start, or stops before you are done with it.

Thank you for posting this! I bought an auction i3 that was backed into with a trailer hitch, which broke the blue trim sill. I was having a hard time finding a replacement because I didn't know what to call it or how to remove it. Thanks for taking the time even though no one helped you!

I have repaired similar damage on a 2014 bev with DC fastcharging. Without fastcharging, there would be one less connector than what I see in the above photo. A broken motor mount allowed the motor to hit and damage those low voltage connectors. Fixing the connectors was not enough to get the...

I have heard of people thinking the car is accelerating on it's own when they are regenning and then hit a bump which causes the decel of regenning to stop temporarily. Another thing that has happened - because the car does not "creep" in drive, people can forget the car is in drive while they...

Are you sure the high voltage battery is still charging normally? I don't understand how that would be possible if the big fuse in the safety box is blown. That should separate the HV battery from the rest of the car. It makes sense to me that the battery side of the safety box checked out fine...

A small amount of spark is normal, You are charging up a good amount of circuitry, including capacitors. If you have a voltmeter that also measures current (ammeter) you should see the current tapering off after you first connect it. Keep an eye on the voltage if you have reason to think it is...

Wondering if anyone has experience with an i3 that has been through a flood. If they run and drive, do they tend to continue to do so, or do they develop numerous gremlins? Might be a way for me to learn more about these cars, but hard to know how much to bid with out knowing how much thouble...

Thanks so much! I have heard it was some big expensive problem if you lost your last key, so I have always made sure I have two. I see keyless salvage cars come up for sale every so often and have avoided considering them. I wonder if dealerships have any issue providing keys for salvage...

What does it take to get a i3 sold with no keys running again? I imagine there is some module that needs to be replaced that perhaps comes with a key. If that module has to be coded to the car, can you do that through ista or do you need that magic BMW test box equipment that costs something...

Apparently, ya just treat it like any other auto A/C system. I just took my 2014 bev for a 126 mile drive and got home with 25 miles range showing on the guess o meter. A/C worked fine. Still not sure if the batter cooling was used at any point.

Rather than say they made a "mistake" I would prefer to say the made a "decision" based on their priorities. They want the car to feel nice (not harsh) to people test driving the I3 for the first time, so that they buy the thing. MY priority is to have less tire and rim damage, more range, and...

I think they all need higher pressures, but especially the 20 inch rims, as they have less distance to go before the rim bottoms out on a pot hole.

Is there anything special about removing and replacing the refrigerant in the i3, besides the type and the amount and the special non conductive oil? I imagine there are valves that keep the refrigerant from cooling the battery when the battery is at a good temp and you are only asking for...

I don't see 120Ah packs up for sale. They must be somewhere. On ebay I see a lot of 60Ah, and occasionally a 94Ah. I saw a 94Ah on ebay for a 60Ah price ($3359) and snapped it up. It is from a 2017 whose heated seats still worked, so I know it was not locked up from the accident it was in. If...

Ya, sounds like a rip off! Is you air conditioner working? Even if it was not, I believe it would shut down with an error message rather than burst into flames.

I tried my local dealer first, and they told me the CAR WILL CALL THEM when the battery needs to be checked! I interpreted this as "we don't want to work on your electric" When I brought it to a dealership that does work on a lot of i3s, they didn't check the battery as requested, they said it...

I brought my 2014 i3 bev to a BMW dealership to get a hv battery capacity check done. I had been seeing the secret menu estimate of battery capacity bouncing around from 13.2 to 12.8 and back. They seemed to want me to phrase the request in the form of a complaint, as in "I am experiencing...

I have a laptop loaded with ISTA software and cable. It has helped me troubleshoot wiring damage, but I am no expert. Do you have any instructions on how to use it to test HV batterie state of health?

Yes, BMW switched to stronger bracket, mounts and bolts a few years before your car was made.
