BMW SADS Conversion

[Previologist]

I am the person who started the discussion on YPG. i don't have time to research all of your links at the moment (at the public library) but if you are suggesting Febi is a reboxer I'd disagree based on what I know (which is not everything). While I only got the info that they make them for BMW from one online review, I just ordered the (hopefully correct) Febi couplers from Pelican Parts, a trusted BMW supplier and they say Febi are the highest quality and always made in Germany and they have never had a complaint. Since BMW drivers use a lot more than Previa drivers, I took that as a pretty overwhelming endorsement.

I ordered the ones referenced http://zenseeker.net/Previa/PreviaMa...DriveTrain.htm

BMW apparently use two Flex Discs which were very similar in size to the Previa coupler:
BMW 26-11-1-225-624-M57 is the smaller 78mm diameter Flex Disc with 10mm Bolt Holes - this is the one you want

I sure hope those are the right ones because they were supposed to put them on today on the van I'm in the process of buying.

I'm not going to claim any great expertise when it comes to these couplers - I was documenting a lot of web-searching and forum-reading I've done (as much for myself as anybody else for later on!). It *appears* that the vast majority of BMW couplers are manufactured by one German company (SGF) and then private-branded. Whether other German firms actually make their own under license or using their own proprietary process is something I couldn't figure out.

I'd bet the biggest downside of using these might be the failure mode - rather than rattling, they'd rip apart in a stringy blowout (another lively discussion on the YPG site as I recall).

Hopefully the ones I took from my donor are real OEM replacements so I won't have to deal with this any time in the near future. It's not like my AC is going to strain them as it hasn't worked in years.

I don't think anyone has actually had them blow out though, have they? I don't remember that discussion but I haven't read a lot of the discussions over the years if it didn't interest me at the moment. Other than remembering that some people had used BMW couplers I didn't know much before I had to research it a few days ago.

PS-I'm most definitely not an expert at anything automotive lol..
