Probably a drain hole or weep hole. Could be there to drain water in an oddball situation or was used to drain the hood during manufacturing when the car body got dipped in a bath prior to painting. Or maybe it was used to help position/locate the hood part during assembly. There are holes...
I remember seeing a video with Tada where he said they liked the steering feel better without the braces, so they obviously have a noticeable effect. I would not be surprised if it made the front end a little edgier and easier to push around.
Few? Pretty much every BMW in the last couple years has it as an option. It works great. Phone and car do a handshake with BlueTooth and then WiFi takes over. Great sound quality.
Cool! It is kind of annoying how these newer cars disable themselves after an accident. It makes even simple stuff a minor project. It's really frustrating on an AWD car.
Don't know about cost/availability, but the Z4 strut tower braces will bolt right on:

If every single light is out in the unit, I'd suspect either a gross wiring problem, connector fell off, ground problem, or computer/software problem. These units are really complicated with a bunch of pins on the connector, so for all of the unrelated lights/functions to go out at once sort of...
They scrambled/randomized the LE numbers, so there isn't any correspondence between the plaque number and the build order. VINs would be the real indication of the build order, if you can compare those.
It doesn't affect the odometer and you can prove this to yourself very easily if you don't believe me and all the prior BMW experience.
The speedometer offset is not an error or due to difficulty measuring speed, it's an intentional software tweak to make it read high to the driver. As...
This was actually learned from 2-3 independent sources as far back as the early spring of 2019, so I'd put it as highly likely. And it fits with what BMW does with engine upgrades on a routine basis. Already, BMW models that came out with the B58 in 2017-2018 have gotten power bumps for...
The key with the diff is to stay away from the fins, the seam, and the gasket area. These pictures clearly show that. In practice, a lot of finned diffs get damaged because people don't know any better or don't pay attention.
The GT350 is a bit of a paradox -- the specs push it into an upper group (Corvette, etc), the price lands it in this group, but the interior quality/feel is a letdown across the range. I couldn't even really take Mustang models seriously just because of the interior and some of the overall...
I wouldn't necessarily worry about the 5w versus 0w depending on the climate, but to go from nominal 20 weight to 40 weight is a big jump and I wouldn't be comfortable with that. It will affect a lot of things in the engine. If the engine is designed for 20 weight, then running 40 weight will...
I agree that connecting a maintainer directly to the battery is preferable, especially when the battery can be isolated from its loads. On my boat, the shore charger is wired directly to the batteries and a battery switch isolates the batteries from their respective circuits.
On a car where...
Dang, that is a great way to describe and show it. I think "energetically" is the word I have been searching for all these years. It just took German > Japanese > English translation to reveal it!
+2mph is the standard for BMW speedos. How the heck would this have anything to do with depreciation? It doesn't affect the odometer, just the speed displayed to the driver.
