--->cooper44; I'm not aware of VW's diverter valve issues, but then again, I'm not involved in the VW universe. Perhaps DiD or VdubDoug would know.

--->Koopah; Thanks for the e-mail When it arrives I will investigate if a modification to the design will effect the Yo-Yo.

Cheers,
Ryan

 

Ryan,
I forgot to mention, Thank you for doing all of this extensive research. I really appreciate all of your hard work.



Craig

 

Bravo, Ryan. Thanks for putting in all this effort. Hopefully a solution will emerge. (Any chance we could do a low-tech workaround, while waiting for the real fix? Perhaps a stronger or weaker spring? Something that doesn't completely disable the bypass valve?)

I've had yo-yo since the end of my break-in period. Oct '02 build. (I think that's right. Delivered in Jan of '03.)

-Dave

 

Craig (and everyone) - thanks for the kind words! Hopefully my investigation will yield a (relatively) quick fix from MINI, and everyone can get on with smooth Motoring!

---> Dave: apart from tying the bypass valve shut, there really isn't a good way to impliment an additional external spring. It's so tough to get in there without removing a bunch of stuff (throttle body and airbox) that tying it shut is the best deal for now.

Ryephile - you're the best.

V36 fixed the stumble in my May '03 MCS but the yo-yo is still there. It seems to be reduced in colder weather and with a warmer engine for what it's worth.

This is great, guys - anyone else out there?

 

Count me in to. Just had V36 last week at NW MINI in Tacoma and still have the YO-YO.
Thanks for all your hard work.

Mild yo-yo...

 

Thanks for all the hard work, Ryephile.

TD68072 05/03 build has yo-yo

 

Thank you Everyone for your help!
My appointment is very early tomorrow morning. I'll be sure to give everyone up-to-the-minute feedback on what I hear from MINIUSA Engineering. As I kind of suspected, the build date range is broad indeed! From a March '02 build all the way to November '03 builds, looks like the Yo-Yo has been around longer than I thought.

Until the fix,
Motor-On!
Ryan

 

Ryan,
Great! Now I'm going to have NAM on all day! Constantly hitting the refresh button!
I look forward to hearing what they have to say.

Craig
