I had a chance to check my bov today. All clean with no tears in the diaphragm. I think my problem was me living in a 91 octane state and having record heat.

Have you considered meth/water injection?

I have and I can't wait to install

Everything in stages - gotta get my catch can done asap.

FYI - http://pure-gas.org/ pointed me toward a station that has 93 octane ethanol free gas. Looking forward to filling up the tank on that in a couple days.

 

Stock 2007 R56 BOV failure here. I have 53k miles on my cooper S and had the P28AA code thrown last week.

I ran the alta software stage 1 for about 6 months now when the car started to misfire. I took it into the stealer, and had carbon cleaning done, also the turbo's oil line was leaking around the mount into the turbo. The inside of my engine was disgusting, I paid to have the cleaning done (walnut blasting), and have the upgraded turbo oil line/mount installed. About two weeks after that work the car reduced power and threw the P28AA CEL.

I took the car to the dealer figuring that they must have screwed something up since the turbo needed to be removed (according to them) to replace the oil line and mount. So I figured maybe the BOV got screwed up then. The tech thought that was weird I guess so he decided to do the HPFP failure test which showed my HPFP was not performing properly. He replaced that, but didn't do a thorough test drive. Right when I picked up the car I got on the freeway, gunned it and threw the BOV code again.

So finally they're giving me a BOV on the house for my troubles, which they should since it's only about a 60 dollar part.

Anyway long story short, my OEM bov failed, and the car threw a P28AA code. What do you guys have cooking? A better BOV? Are these known to fail frequently? I would certainly buy a better part to make sure the car keeps running.

 

We are working on something. We don't have an ETA yet, but a new BOV is in the works that should be more reliable than the stock part.

 

I can't wait.

 

Also, eagerly waiting for a part the will hold more boost than the stocker. Any update on a release date? I need to replace mine ASAP. Would it be worthwhile to just upgrade the spring while waiting for this part to be completed?

Thanks Chris, Still having high boost bleed off over 20 psi. Checked the OE DV and diaphragm is fine. Also had the intake smoke tested for leaks and didn't find anything. The only other thing to change would be the Factory DV.

 

I have your BOV Spring Upgrade, and have recently noticed it fluttering when I was doing a data run. It happens most when I'm in third and let the RPM's get really low, gun it and then let of the gas.

 

Scooter, try cleaning out the shaft that the spring sits in. There may be blow by in there that is causing the spring to not open when it's supposed to.

 

The problem with my blow off valve is that I don't have one yet. Alta will you give me one? =]

 

Haha, we are working on the blow off valve still, probably no hand outs though!

 

Chris,

Ask Jeff if I'm aloud to talk yet??


Ray Maz...

 

I guess thats ok.... I'll just have to be REALLY REALLY good this year and maybe Santa will bring me one next time ( If those Alta elves can make the darn thing by then ) We got a new Mini dealership in my neighborhood maybe a year ago and the difference in the amount of coopers around town is just increasing rapidly. I'll have to get out there and spread the word about you guys, I really enjoy the fact that you guys are active on these forums. Good luck with 2012 Alta!

 

Thanks conrad! We will have this part out in 2012 for sure.

 

Eagerly awaiting something to stop my bleed off problem. I've tried your "upgraded" spring and that did NOT work. I'm still getting bleed off above ~20 psi. I hope this BOV will fix my issue.

 

threw p28AA, I'm guessing the resistor is failing? Fresh install.

 

The resistor could have either fallen out or isn't making a good connection. Double check to make sure that it's still there, and that the prongs are folded in half to make the best connection to the plug.

What happened to the consideration to release an upgraded diverter valve? Did it die on the drawing board?

 

Hello, we've actually been selling our upgraded diverter valve for the last 2 years or so. It's available on our website to purchase right now.

 

Yes Chris, thanks for the quick reply. I'm sorry I thought something was in the works for 2011+ MCS. Your site indicates the valve is not compatible with the later R56. If this is not the case please let me know and I'll make a purchase.

 

Sorry for the misunderstanding, we do not have a diverter for the 2011+ cars, since there really isn't an easy way to get a boost source on those cars. Usually we'd use the intake manifold for a boost source, but the newer engine doesn't run boost or vacuum the same way as the older cars in the intake manifold, so our kit simply won't work as intended, sorry about that.

 

I am an owner of 2009 JCW COOPER with 36.000klm. i've installed the alta blow off spring and seems my car loose the previous response was having with the OEM spring also i noticed in neutral when i press the throttle the turbo seems no boosting at all only in the range o 5.000 -6.000 rpm
Please inform if there is a problem with my turbo because i am planning of having a long trip.

 

Forza, sending PM.
