Re: Battery range continues to drop when Rex cuts in.

I would strongly recommend coding "hold state of charge" which adds an option to start the REx as low as 75% state of charge.

Non-US i3s all have this option by default.

Re: Set a maximum charge limit

There is less regen braking above 90%, right? For that reason alone I would like to set a lower charge limit for my daily use. I use between 0-10% of the battery most days.

Re: Metallic rattle sound from passenger side over deep bumps

Thanks for your thoughts. I was thinking suspension, but it's not any louder when the windows are down. The sound is definitely eminating from the interior. I took a look at the motor/engine cover and three of the neoprene nuts were destroyed (part #16: https://parts.bmwnorthwest.com/images/parts/BM...

Re: Metallic rattle sound from passenger side over deep bumps

Thanks for your input. I have been knocking and tapping on every surface in the car, but no luck so far. It really sounds like it's in the cabin, but it takes a sizable bump to activate it.

Metallic rattle sound from passenger side over deep bumps

I’m hearing a metallic sound that almost sounds like two coins touching when going over deep bumps. It’s from the left side, possibly the seat or dash. I have removed everything from the car and searched for loose objects, but no luck.

Has anyone heard this before? Thoughts on diagnosing it?

Re: Very loud REX - does a Motor Bike Silencer work?

Were you able to try a different REx car? I suspect the first one had a problem.

Re: Very loud REX - any solutions?

During my test drive at this deal, the battery was about 2%. As soon as he powered up the car ( every time) the REX came on with this non-stop rattling. I might still buy the car IF 1) the range extender trigger can be adjusted or reduced to 2% instead of 5-6% 2) when the maintenance cycle starts i...

Re: Very loud REX - any solutions?

Could you give a decibel reading from the NIOSH app (dBA and dBC)? A video might also be useful, but phones typically add some compression. I have driven two REx models extensively, a 2018, and my 2017. The REx on both was extremely muted, all but inaudible at highway speed. I think there is somethi...

Re: Adjust high-beam/main beam headlight

Does this require a special tool?

Re: Recurrent for tracking battery health?

How did their health report compare to the Batt Kappa Max readout?
