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. Prevent mistakes like these ha

Never seen the VANOS system explained like this. Great presentation. The problem I have seen with these oil pressure control systems is the customers lack of maintenance which cause sludge and oil deposits to block oil passages. This goes for the modern timing chain systems as well. Thank you DiagnoseDan

I know this because i did a similar thing on a Rover VVC engine once but it was with wires swopped between the vvc unit and something on the inlet manifold.

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!

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

2 жыл бұрын

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...

The vehicle owner did his own repairs but kept making it worse off so he brought it to me. Upon asking him questions he had done oil change and replaced both vanos sensors. Owner had missed the clogged vanos filter screens so I cleaned them. The vanos sensor connectors were switched and the plastic retainer within the oil filter was missing. Once these were corrected the engine ran much better.

Omg Dan. Because I couldn't imagine the shop did an installation fault on the Vanos parts, I hoped they didn't switch the Vanos selenoid plugs! Unfortunately, they did🙃😮. Thanks for sharing. Regards Nico.

@@Stoney3K the solenoids that extend through the opening on the front of the cylinder head are identical, same part number for both cams, it’s the VANOS sprockets that are unique to each side.

It’s definitely the small things that can catch you by the 🏀🏐🎾⚽️⚾️🥎

It's relatively uncommon to see identical plugs close to each other. How often do you see anyone spending time labelling every plug they remove?

@@jix177 There's no need to label every plug. Just the ones like this that can be easily switched. It's less than a minute with a two dollar paint pen vs. three grand in parts and who knows how many hours labor............

There were some guides and sleeves missing that would make this mistake nearly impossible. If you look closely you',ll see the even marked the connector with white Paint

Has nothing to do with the Car, it was a mistake from the mechanic

The way you explain everything showing examples sets you above many others. Brilliant step by step diagnosis and a no nonsense approach with intelligence and creativity! Love your videos Dan. Kind regards.

Hi Dan, since i joined your Facebook page and KZread channel every episode i grow more confident in starting my project car. You are the real deal in problem solving and analytical thinking. Thank you.

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!

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

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

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

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.

The Explosion sounds always makes me jump !! EXCELLENT AS USUAL THOUGH!
