The same deal with the splines that engage with the camshafts on each end, they could have easily put a mirrored notch on each of the wheels so they would never be interchangeable in the first place.

I mean ya gotta be pretty fucking incompetent to mix these up. Everytime you remove connectors, you mark them or you trace them. Even the BMW workshop manuals tells you which one goes where. Again, this is just pure incompetence. I'm a DIYer with no mechanical professional background and cmon even I don't fuck up like this. EDIT: After reading the comments, I concur it is stupid. It's easy to make it fit one spot when it's not. It's just at the same time, I feel like it's also stupid to mix them up but yeah... I guess that's the point of good design.

Agree, but huge shame on the BMW engineers who decided to put two similar type of connectors at such a place. Of course, as long as the cable with this connector can reach both sockets, it must be irreplaceable - absolutely not what I expect from a BMW engineer. @@Diagnosedan

[@kain0m]

@@AMGswede likely, the solenoid is the same for both Intake and exhaust. So keying the connectors would increase the number of unique parts, increasing cost and likelyhood of "out of stock". Of course, some Poka yoke would be nice, but not at all costs.

Point taken - cost is of great importance. But then BMW could have color coded the connector on the wiring harness.

I have also made that mistake of incorrectly switching the vanos intake and exhaust solenoid connectors after removal, cleaning and reinstallation. This lead me to pre-maturely replacing both solenoids, both camshaft position sensors and both vanos check valves only to realize later the solenoid connectors were opposite. I put both the old solenoids and camshaft position sensors back in and realized the actual problem was only a faulty intake camshaft position sensor. Anyway, very good video with explanation of how the vanos works, view of the all the parts and tools used to diagnosis vanos problems. Also good reminder to not throw parts at a problem. Thank you!

[@GNX157]

No way Dan, I’m just not believing this. There’s about a dozen BMW engineers who should be fired for this. No way should it of been designed for this error to happen so easily. Those wire looms should be tagged or labeled. The connectors themselves should not be interchangeable, the connector colors should be different. Take your pick but I lay this fault squarely on BMW’s shoulders first.

[@Diagnosedan]

There were some guides and sleeves missing that would have made this mistake nearly impossible

[@daysofgrace2934]

But it's this kind of knowledge that will allow you to get paid a higher rate. Otherwise, anybody would be able to fix it...

[@aeroearth]

A basic tenet of design which the Japanese call "poka yoke" is that it should not be possible to assemble such parts incorrectly. So the electrical plugs to the solenoids should have been physically different and the machining of inlet and exhaust vanos units and camshafts physically different so impossible to inadvertently swap them over. Same principle to be used for fitting the cam assemblies to the engine and indeed for the WHOLE CAR.

[@stevesaunders7810]

The Vanos units at the cams I get. It's bad engineering, and they should be keyed. But NOT the solenoids. They are the same part number x 2. Just don't stuff up the connections. If they were two separate parts then BMW would need to manufacture two different parts for the 'same' job, and have to charge more for them. That would result in increased manufacturing cost, warehousing cost, etc, etc., right on down the supply chain. Sure, design better connector reach/placement, but they did. Like Dan said, there are guides and sleeves missing...

Most interesting, teaching, detailed and understanding video I’ve ever seen about the vanos system. First video watched, didn’t think twice to like, subscribe, comment and share!!!

After watching this vid. It seems that BMW overengineer everything on their cars, unless the car is in warranty i would never think about buying one, ever!

[@Diagnosedan]

Thanks for watching

[@alanpartridge2140]

Overengineered? This is really piss poor sloppy engineering, it's easy to get the connectors so they can't be swapped

[@YouTube.TOM.A]

How sincerely can I thank you for the information that you share, Words escape me. There are some folks on the internet [ hint hint ] calling themselves technician who find every opportunity to defame and lambast BMWs and Mercedes. I will never say that there are not some models that I wanted to release the brakes on a steep cliff, [ I would have if I had a ride home ] but I will never stop learning as long as talented people like you exist.

My question is, does the customer pay for all those unnecessary parts and extra time spent on sorting this mistake?

[@Diagnosedan]

That shop bought this car to resell it,so they are paying for it themselves.

[@csours]

The most literal instance of Murphy's Law! If anything can go wrong, it will. Those connectors need to be keyed.

[@Diagnosedan]

Thanks for watching Cameron

[@dealerauctionnightmare4689]

marking them would have worked....🤷‍♂️🤷‍♂️🤷‍♂️

[@abdulh9687]

Great video Dan! Thank you for having my back in the workshop, I learn a lot from DDTSB.

[@Diagnosedan]

That's great to hear!

[@Cimon1998]

I really enjoy you way talk and express the words, Clear speech, not to fast or slow, Loud and Clear. And you know we are here to learn so you take it easy on the newbies which many Youtbers seems to overlook. Great Video even tho I didnt search for this nor sure if this would make a contender of my BMW faultylist. And a Beer, for me? The AD showed me that Coca Cola were the one up for grabs. :D

[@bojanlegner7051]

One of the best videos I've seen, very informative and educational.
