Not the first product to do this. Jura coffee machines also have their own oval-ish fasteners.

In fact, it's really quite amazing that car manufacturers, generational artisans of the vendor lock-in have not been doing this at a far greater scale. Think of all those generic screws they could be charging $50 each for. No one buys or doesn't buy cars based on the screw heads. If they did they'd also reject cars that require thousands in probes and an annual subscription to use them, and they don't.

It's not even that they don't have their own screws made by tier 1/2s, as if you look in a car, many seemingly-ordinary screws do in fact have the brand and part number stamped in the heads - presumably for stock and quality control purposes during manufacture.

People are indeed slowly checking out of buying new cars.

gessha• 7 months ago

Problem is if we bury our heads and drive old cars, when they give out and it’s time to buy a new car, all the news cars will have so much of this crap in them they will be unusable and you will be stuck with a lemon.

blell• 7 months ago

This is outrageous and anti-customer. I’m completely sure the EU will be all over it any day now.

rany_• 7 months ago

Not if it's their own car industry. They'll only throw the book at foreign companies.

tpm5• 7 months ago

All of that will be accessible for third parties, because afaik it has to be in the EU. The cost is a different question, but I think that's not a surprise for BMW customers.

xienze4• 7 months ago

I don't see how "oh third parties can get a bit for it" is really an acceptable answer. Lightning cables are readily available but that wasn't consumer-friendly enough for the EU. I think the parent is right, let Ford try this and see how quickly the EU goes after them, because this is quite frankly very anti-consumer.

Tarsul• 7 months ago

No. No, you don't understand. This is actually pro-consumer because if the patent is enforced, other car-manufacturers cannot pull this stunt. So, thanks BMW, good job for keeping anti-competetive practices at bay by patenting them.

Sparkle wrench can handle it.

bovinator23• 7 months ago

Even if it were fairly specific, I’d be surprised if a similar tool couldn’t be 3D printed with DMLS. It’s possible that due to torsion requirements it would have to be molded, which could be much more expensive.

Either way, this is hardly a case where others will be prevented from removing these screws for very long, even if they were to try to enforce that others couldn’t produce a similar tool because of the logo.

It is a sad state of affairs when the only way to attempt to get others to use your services is to attempt to block them. But, unlike attempting to remove DRM encryption, where it might be a challenge to reverse engineer, a physical object of a single standard material can be easily scanned and reproduced.

zrobotics• 7 months ago

This is an inherently weak fastener design, it requires the driver to have 2 separate 'pins' to fit the 2 quadrants of the logo. Even with a proper forged tool this will be weaker than a torx or hex bit. Basically the only way this would be manufacturable is 2 forged pins shaped like quarter circles that are pressed into a socket.

This isn't that different to how other bit sockets are made, but instead of loading the bit in torsion, it will be subject to bending forces to loosen the bolt. This will make it far weaker than other tools. So good luck loosening these once they have a few years of corrosion on them. Plus, with the head design, they'll be far harder to drill out to get a bolt extractor on. Although 3d printing and scanning don't really help that much here.

mschuster91• 7 months ago

Even if it were fairly specific, I’d be surprised if a similar tool couldn’t be 3D printed with DMLS. It’s possible that due to torsion requirements it would have to be molded, which could be much more expensive.

A CNC mill should also be capable of creating an usable driver bit, or in a pinch, drill out 1mm center of an ordinary + bit.

voidUpdate• 7 months ago

Plus, if you you are handy enough to be taking the screws out of your car but don't have a CNC mill, you probably know someone who does, who would love a little weekend project to turn you up a nice BMW screwdriver

… So they didn’t want to just pay Bryce Fastener to give them their own “proprietary” screw? They’ve been in this market for decades with “custom” security screws for vendors, among other things.

Youden• 7 months ago

Isn't it relatively trivial to remove one of these by epoxying something to it or using a drill or dremel to modify it in some way (e.g. dremel a slot that a standard flathead can turn, or drill and use a screw remover)?

Or is the purpose less to prevent people from removing the screw and more tamper evidence?

Even in that case, with a photo or impression of the screw head, an unauthorized key/bit could be produced with with 3D printing (JLC3DP offers it cheap) or EDM.

throwaway173738• 7 months ago

If its on the wheel hub you’re going to need more than a dremel to do that, and you’re going to need something that breaks less than a flat head. There’s a reason they don’t make flat heads for impact drivers.

kotaKat2• 7 months ago

The button head is designed to be low profile and is rounded off enough to prevent tools from getting a good bite into it to cut a slot; on top of that they’ve designed these fasteners to torque super tight down (including ‘claw-like’ serrations on the bottom of the screwhwead) to basically require their tool so the bit doesn’t snap off if you try to make a duplicate.

cookiengineer2• 7 months ago

That already is old news, lots of manufacturers do that.

For example, the Passat 3B and later platforms introduced proprietary screws for the wheels and brakes, so you weren't able to change them yourself.

Same for all kinds of sensors that will go rogue when the car is turned off and you change a sensor on the engine. All firmware gradually was modified each generation to allow less modifications and less self repairs, and less repairs by third party workshops.

Also, the Golf 2 platform for example had a very sturdy engine running beyond 1 Mio km easily. What do you think happened with the Golf 3 engine design? They made the camshaft structurally weaker, so the engine will blow up more easily. The rest of the engine is almost identical. Talk about being bad at hiding planned obsolescence.

There's many more examples like this, acrosd every manufacturer. The real reason why there is so many people on race tracks driving old cars is because they're easier to modify, easier to maintain, and easier to buy replacement parts for.

It's ridiculous if you think about it, and really frustrating that there is no legislative intervention against this.

markus_zhang3• 7 months ago

Guess eventually people will buy the cheapest cars and treat it as a consumer product that breaks down every few years, like a laptop. Or simply find a remote job and rent a car.

Welcome to the Dystopian world.

georgefrowny5• 7 months ago

Guess eventually people will buy the cheapest car

It looks like lots of people choose to lease very expensive cars, and give them back after 3 years for a new one, dropping a obsolescence time-bomb onto the second-hand market and providing a strong signal to manufacturers that there is a substantial maintainability-insensitive market segment.

I am still surprised that no manufacturer has a balls-out "buy our cars, they will NEVER DIE, anyone can service them, and your kids will still be driving them" model, as they might have lower returns from not gouging over subscriptions, planned obsolescence and parts and software lock-in shenanigans, but they'd instantly capture a market segment.

elzbardico4• 7 months ago

70's American cars were not very far from this. The competition from Japanese manufacturers really helped to improve this.

And ironically, the reason why Japan invested so heavily in high quality was to overcome their former image of low quality products that severely hampered their ability to sell to international markets.

I am not a libertarian that holds a religious belief on the infallibility of the market, but a lot of times, the market gave us better outcomes than any regulation.

2026iknewit3• 7 months ago

I believe its more about optimization for price and minimum amount of km you need to design something for.

And in regards of screws: If you have too many laypeople doing stupid shit for critical components, you might also think 'lets fix that by adding a barrier'.

DennisP2• 7 months ago

Why would that be your problem? Make it a warranty violation, and they can either get it fixed themselves, or pay you money you wouldn't have gotten otherwise.

rollcat3• 7 months ago

[...] so you weren't able to change them yourself.

This should be illegal. You're supposed to do what, stay on the roadside for 20h before an authorized repairman can reach you? What if the weather is harsh, and you run out of basic supplies like food or your medicine?

Towing exists.

chii• 7 months ago

The real reason ... driving old cars is because they're easier to modify, easier to maintain, and easier to buy replacement parts for.

the real reason is that if a manufacturer makes their car same as those repairable, easily maintainable old cars, they will soon lose customers (as they stop needing to buy new ones!).

Planned obsolescence out-competes in a market economy that does not have regulation against it, esp. in a saturated market (like the US). The gov't could legislate, but then businesses cry foul - not mention that these manufacturers hang the sword of damocles over the gov't in the form of job losses (but of course, out-sourcing is OK...)

UniverseHacker3• 7 months ago

I think you’re seeing malice where none exists, particularly in those VW examples. VWs have always required a lot of special tools to work on, but usually for good engineering reasons making things smaller, lighter, simpler, and easier to manufacture. They will happily sell the tools to the public, and for most VW models, a few hundred dollars worth of special tools is all you need for any DIY repair- I personally have accumulated pretty much every VW special tool for every model and year, and find the special tools tends to make them easier to work on for a home mechanic- less stripped bolts, etc. than other cars. A 12 point star on a brake caliper is really not a rare tool, and it is so much quicker and easier than trying to fit a huge socket in that awkward space.

If VW had been trying to make the mk3 engines bad for planned obsolescence, then why did the mk4 engines like the ALH TDI and the 1.8T earn reputations as some of the best engines made? VW had quality issues in the 90s that they later attacked and fixed, but it was just sloppy leadership and engineering, not a plan.

What engine exactly are you seeing broken cams on? My guess would be this is not VWs fault but a mechanic failing to keep track of the ordering and orientation of the cam bearing caps and swapping them around- they’re line bored and any modern engine will break the cam if you do this. I’ve seen it on a mk2 GTI.

cookiengineer2• 7 months ago

I am not sure if you wanna go into discussing Diesel engines now, especially with all the engine software problems when it comes to AdBlue, and when it comes to Dieselgate, which, by decision of all involved courts, was malice.

While I agree that some models improved when it comes to performance (especially in the 1.8 - 2.0 Turbo range as that's the sweet spot when it comes to cc) and technical failures, I would still say that all newer models have more problems with software. So much that it's really not even necessary to create these problems even in regards to regulatory requirements or safety compliance.

Just thinking about the messy code that I've seen to pass ASIL-D requirements makes my skin boil.

ryeights2• 7 months ago

What do you think happened with the Golf 3 engine design? They made the camshaft structurally weaker, so the engine will blow up more easily.

Wow, talk about an oversimplification. The Mk3 moved from an 8-valve to a 16-valve engine; yes, this adds more valvetrain failure modes but also brings myriad other benefits, increased power, better fuel economy, reduced emissions…

The idea that a carmaker would purposely engineer flaws into core engine components in order to drive future sales doesn’t make much sense.

The idea that a carmaker would purposely engineer flaws into core engine components in order to drive future sales doesn’t make much sense.

There is a legend that Mercedes 190D was built like a tank and this caused customers to not buy the next iteration. Mercedes solved this, making cars a bit unreliable.

salawat3• 7 months ago

You need to realize modern business revolves not around one-and-done, but around recurring revenue streams. To the "business minded" the only thing that doesn't make sense is leaving money on the table.

elzbardico4• 7 months ago

really frustrating that there is no legislative intervention against this.

Ironically, things are like that in a big part because of legislative and regulatory intervention.

They made the camshaft structurally weaker, so the engine will blow up more easily. The rest of the engine is almost identical. Talk about being bad at hiding planned obsolescence.

A lot of such things are just workarounds to reduce weight and meet tightening emission standards.

Every thing that can be built with less metal, thinner walls, lighter metals will be built like that when every gram matters.

Tighter tolerances, increased pressures, increased temperatures, higher rotational speeds. All of this leads to increased efficiency, but sometimes (not always) the trade-off will be decreased reliability.

Any workshop can command WV screwdrivers, at least in the EU. I think the new regulation is that if you don't have the piece, or the tools necessary to replace the piece, you have to produce the plans on how to do it.

I know someone who had an issue with his old WV Kombi, and thought it would be the last drive (Around 2020-2021). He found an auto shop who could manufacture pieces and replaced every single malfunctioning pieces from plans they got directly from WV.

Great, now I need an extra large bit set.

I really don't see the point of this, it won't take a year for that bit to appear on shelves at the local hardware store if people need it. I have bit sets containing ever imaginable "security" bit, security torx are pretty much standard in set now. So are the weird flathead with the middle cut out. You almost can't buy an iFixIt kit without Apples stupid pentalob bit. This is just another bit to add to the collection, BMW will achieve nothing by introducing it.

The design is neat though, using their logo at the head of the screw is sort of cute. Completely unnecessary, but cute.

arealaccount• 7 months ago

I think the schtick is they can block these tools from being sold via trademark infringement.

Thats why the BMW logo is in fact necessary

Kirby64• 7 months ago

This wouldn’t hold up in court, to my knowledge. If you have a tool that is solely designed this way for technical reasons, then there isnt trademark infringement. Just make sure to market it as the “B” screwdriver or whatever. The same thing with the Nintendo case for their logo on cartridge protection, I don’t think that ever held up in court.

dingdingdang• 7 months ago

belorn• 7 months ago

Like with smart TV with advertisements, the locked down cars will provide revenue after sale for the manufacturer. Thus they will mass produce and sell those cars for a cheaper price, while adding a significant markup on the non-locked down cars to be primarily sold to commercial partners at lower batches. The cheaper mass produced one will significant out compete the other ones to the point where most dealers will no longer sell those more expensive versions. Most customers won't even know the difference when they buy the car, and why should the seller go out of their way to inform the buyer when most people just care about the sticker price anyway.

Having locked down products also allow the manufacturer and dealer to form a agreement of sharing some of the post-sale revenue. The dealer can have their own shops for repair which the customer are now forced to use, naturally at a steep markup, and the manufacturer get a slice for every repair. The cheaper sticker price can then be decreased further since the dealer now have an additional revenue after sale. The customer can go to an other manufacturer approved shop, but then how many of those exists in the same city, and the manufacturer can artificial limit how many shops get approved in the same location.

The story is the same across any number of industries right now. Customer choice is not a argument for the manufacturer to not do it. If you as the customer want to opt out, the only choice after a while will be to not buy a car or buy the expensive ones for double the cost.

tgsovlerkhgsel• 7 months ago

You don't entirely get to opt out.

If you crash into a BMW, you'll still have to pay for the now-inflated cost of the repair - most likely through the mandatory liability insurance. Insurance premiums have gone through the roof, to a big part not just due to insurance company greed but because cars and repairs to them became more expensive.

If in Europe, they're going to "fix" that with a €3 flat fee per item to cover "import duty" under €150 in July (on top of VAT which is already charged since 2021).

fsckboy• 7 months ago

People put up with it for Apple, but BMW isn't Apple.

Actually, for making devices I wanted to own and operate, BMW actually has been Apple, and Apple has never been an Apple up with which I will put. But when I test drove new BMWs 3 or 4 years ago, they weren't Apples any more. So I bought a Porsche Apple.

this feature I like in a car is being able to feel the road and the inertia of the car through handling the steering wheel. Too much power-steering or suspension isolation (or something) and it feels like you're driving a marshmallow. Apple computers have similar qualities on many dimensions actually. "hey look, you can cook a marshmallow on a stick and you can even eat it off the stick, let's make the UX be one stick!" "just one stick?" "yes, just ̶o̶n̶e̶ ̶b̶u̶t̶t̶o̶n̶ ̶m̶o̶u̶s̶e̶ ̶o̶n̶e̶ ̶m̶e̶n̶u̶ ̶b̶a̶r̶ one stick!"... "hey look, Steve Narcisstick, you can even poke the mouse the one stick!" "no, I spell my name Narcissdick")

They'll go out there and advertise the fact that they can afford a BMW with ALL features and so it spreads on...

We're also not even talking only about the private customer. It's business cars who are even more relevant.

mwexler• 7 months ago

Watch makers have moved to this model over the last few years as well. The Swatch group has restricted access to movements and parts by acquiring major movement manufacturers, forcing the industry to use duplicate parts, some produced in violation of patents (dep on region). The patents attempt to protect proprietary approaches adding complexity through unique pieces, which rarely add functionality or new value.

BTW, none of this is surprising from BMW. They were the first to try a subscription model for in-car features like Carplay... Or seat heaters. https://www.caranddriver.com/news/a30139034/bmw-apple-carpla... and https://www.edmunds.com/car-news/bmw-relents-on-heated-seat-...

You probably should be getting the automatic serviced every 10 years. That basically involves cleaning it, replacing the mainspring, and applying new lubricant. If it's a dive watch, they would also replace the gaskets which dry out.

Damogran63• 7 months ago

Having just bought a Mini Cooper, I'm in the initial free-services period of the ownership and honestly, if it's the $10 a month I suspect, I'm okay with it. Primarily for the navigation...it really is superior to the Carplay experience (a square in the middle of the round screen, vs a map that takes up nearly the entirety of the screen...IIRC, traffic, Weather, remote start, and voice control come along for the ride.

I won't pay for 5g (phone does that) or Serius XM (for all the channels, I'm really not jazzed about the offerings)...but $10 for the above features seems reasonable.

salawat3• 7 months ago

No, it bloody well isn't, and I kindly request you stop with that nonsense. Remote start is a glorified CAN message paired with either a TOTP or HOTP message. That's it. There should be zero room for a manufacturer to justify inserting themselves in the middle except greed. Goddamn tired of solving problems only to see companies keeping the problem around for the sake of market segmentation.

I haven't used CarPlay since I'm an Android user, but this reeks to me of a manufacturer developing a problem so they could seek rent for the solution.

If there were no financial incentive otherwise, they certainly would have ensured the CarPlay experience was as nice as their own solution as a selling perk.

Terretta• 7 months ago

Seven hours in, all comments assume this is to screw the car owner.

But FTA:

BMW really does want to use these to stop people from working on their own cars. It spells out in the patent that "the shape of the engagement recesses prevents the screw from being loosened or tightened using common counter-drive structures, e.g. by unauthorized persons." That's straight from BMW.

The second sentence is key: "unauthorized" can be woke-speak for thief, and this device doesn't seem to require a single key per car which has been a PITA for VW/BMW in the past.

The first sentence can then be edited to simply:

BMW really does want to use these to stop people from removing wheels from cars they don't own.

Before you object the thieves will just go get the tool: professionals yes, opportunistic, no.

This is enough of a real issue in some places there's a discount on theft insurance for car contents and parts when you have wheel theft prevention devices (e.g. wheel or hub locks). Granted, the insurers might not see this as actuarially meaningful, it might just be extra revenue from people who care about their wheels, but then you'd expect to see it everywhere.
