At 60 MPH indicated on the car's speedometer, both my phone's GPS and my dash cam's GPS show 58. The gap widens to 3 MPH around an indicated 90, and it narrows to 1 around an indicated 30. Thus, I extrapolate a roughly +3% speedo error.
I'll be bumping up my set cruise speed to account for this! With 2021 tech, it is aggravating that a major car manufacturer won't calibrate a speedometer to go the 'actual' speed you think you are going.
Just be thankful it's more accurate than the GOM! Lol Reading about other BMWs it seems that the car actually knows your true speed (and uses this for the odometer) but the display speed includes a programmed offset. This offset can be changed by the dealer but others seem to have had a hard time getting them to agree to do it. It might be something possible to do with Bimmercode too but would probably be in the advanced options.
Interesting, I’d noticed the same error but I figured it was because I put the stock tires on wider rims so the circumference decreased a bit.
I have the same question, as my charging history screen looks like yours. Could this be a different presentation on the iPhone version of the app? Mine is Android.
Thanks for all of your posts. But, I have one question -- what type / brand of adaptor did you use for the Tesla charger to MINI in your friend's garage? Was it Tesla to J1772? Or Tesla to CCS? I have read news reports that Tesla plans to "open" its proprietary supercharger network later this year to public use, but I am assuming that this will require a Tesla to CCS adaptor in order to work for a MINI SE, and I can't seem to find one (yet) online. (Or, do I have this all wrong?)
Tesla supercharger adapters don't exist yet, the only adapters available are for the destination (home) chargers which are Tesla to J1772. If/when Tesla opens their network, I'm sure they'll be the only ones selling an approved adapter and it won't be cheap...
And this is the specific adapter I bought for the non-supercharger action: https://smile.amazon.com/gp/product/B07V7V2QT8/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
I assume Tesla will have to add CCS-compatible connectors to their Superchargers if the company wants to get the government bucks that will flow to charging-station providers. Whether only one Supercharger in a group of 20 will be required to offer CCS compatibility remains to be seen. This White House Fact Sheet doesn't specify CCS compatibility, but based on Biden not inviting a representative from the non-union Tesla company to the recent EV mobility conference, I doubt he's going to allow Tesla to require non-Tesla BEV owners to purchase adapters.
Hi there, I just bought the Lectron adapter and went out to try it out. There are 4 Tesla chargers that labeled as Tesla wall chargers in a public park. I connected the adapter to the Tesla plug and waited 30-60 seconds before plugging into the Mini. Once plugged in the screen in the car shown "Calculating" as in the attached photo and nothing happened even after 5 minutes. I got the same result with two other chargers. Do you remember how long you have to wait before charging is started?
On my home Tesla wall charger, there is no delay; the MINI does its handshake and starts taking charge before I walk around the car to get out of the garage.
I did not have a longer-than-normal delay before it started charging at the Dentist office I used as well as my friend's garage charger. But there were several hotels I tried with Tesla chargers where I had the same problem you did. So it must be hit-or-miss.
