According to the guy over at bimmer-remote, the latest istep version for the supra is 22-07.

I sent him an email to see if he would be able to update the ISTEP and all the modules along with fullscreen apple carplay. He said the ISTEP would be updated to the latest version but we shall see.

...along with fullscreen apple carplay.

All updates post-brake-recall update should have fullscreen carplay so that should be already in order when you update

My 2020 goes in on Wednesday for the latest code. Had the issue present itself again recently. Twice in the same day. I’ll report the iLevel when I get it back.

Since my last post I’ve driven exclusively with the TC off (single click) and I’ve had zero issues. Surprisingly I actually enjoy driving with TC off, the car seems much more manageable and easier to predict. With TC on, I always felt a little uneasy about losing the rear end. Weird.

Yup I always drive with one click off.

Just got back from the dealership. They installed the latest available iLevel:

^^^ Thanks! Anyone know what modules were updated in the July release? Strange mine was updated in Aug but got the March iStep.

The curiosity of whether or not this will happen again on the 6MT is killing me

It hasn’t happened to me yet in my 2022. But y’all got me wondering and extra careful when I pull out in traffic. Giving myself extra room now regardless

Will this require me to unlock my ECU to upload my MHD tune again?

I do have to report something new that I think may be related to this latest update. Twice, yesterday, my car made a loud, almost purge-like sound. First time it happened, while slowly coming to a red light with the windows open, it sounded like the rear driver-side tire suddenly and rapidly deflated. Startled the crap out of me. Second time it happened after I parked the car in the garage, had shut it down and was grabbing bags from the trunk. Almost sounded like the EVAP system purging or releasing pressure??? Never heard it before. Anyone else?

Does anyone know how long the update usually takes? Is it a matter of hooking up a car to some interface and that's it?

Went to the dealership today and guess what.. they refused to update anything, didn't even check the firmware version, and didn't even look at the logs. Took me on a drive instead where I obviously couldn't replicate the issue.

No evidence = no warranty service.

My next move is to contact Toyota, which, apparently, the dealership can't do on my behalf
