2021 40i - error messages
These look familiar to anyone? 2021 X7 40i with under 20k miles. Popped up today.

Does a bear shit in the woods? Lol. I’m in Memphis, it’s pretty hot and humid in the summer. It’s making a squealing sound in gear but not in park. Maybe a belt is loose?

Thank you for the replies. I’ll try and remember to report back. Whatever it is should be covered. Dropping it off in the morning.

I don’t think so, the faint squealing noise was standing still but in drive. Honestly it sounded like a belt.

Nah he said I could drive it in. So hopefully the tow won’t be needed!

Not sure about the 40i, but most cars now use a single serpentine belt that seems less likely to slip than the several v-belts in older cars, unless perhaps the engine has been experienced considerable aggressive acceleration that might stretch it. A trip to the service dept seems necessary to sort it out.

On the topic of loaners - I enjoy getting to drive these other models but they’re always base models with very little options, if any. Understandable and grateful to have them but these base sport seats SUCK! Experienced them in the X6 and now 530. I will never drive a BMW with those seats. I’d rather just get a different brand all together. The multi contour changes the entire experience for us.

They couldn’t replicate the error message. They did see it stored and it did point to an alternator fault of some sort. But everything checked out fine. They updated software and test drove it… they test drove it a lot. More than I was comfortable with but I trust my service advisor and basically told him that and said “whatever YOU think is best” and basically put the responsibility on him.
In the end, just a software update and chalked it up to a computer glitch. Hope that’s all it is. Of course it’s all warrantied so no charge… so they had to try and upsell $150 worth of wiper blades. I passed.

I saw on another forum an alternator bearing that had frozen. Caused the belt to squeal and the battery failed to charge. Might be worth while to check the alternator mechanical integrity -- could be a bearing on its way out, and I'm pretty sure bearings don't throw error codes.

In the 18 or so months I’ve dealt with them, my dealer has been pretty good about getting things right even if the first attempt doesn’t get it. I’m not worried about them treating me right, but I don’t want my wife to get stranded.
