You will probably have to remove the bypass valve ti inspect it...

Do a quick search and you'll find some very good how-to here.

I rememberposting one here, from Detroit Tuned, with pictures... it was not too hard to do. And at the same tine, you could also adjust the bypass-valve.

 

My removed bypass valve looked and seemed to work fine out of the car besides the normal misaligned butterfly plate problem. But after I replaced it, I had no more problems. I still don't see how the valve would not close since the spring will close it when there is little or no vacuum.

anyone got a picture of this bypass valve??

 

This is the modified one, but it looks the same as stock.

Did you re-adjust it before reinstalling it?

Did you inspect the vacuum hoses too while you had the intercooler removed?

btw, glad your problem is gone...

 

I ordered a new valve and adjusted it before I installed it. All the original vacuum hoses are still installed and working fine. I tested the old valve with a vacuum pump and it seemed to perform perfectly. It didn't bind and the spring seem fine so I don't know why it was a problem, but replacing it made the warning lights and limp mode a thing of the past.

Any pics of your MINI ? SSR wheels and Wilwood brakes =

 

SRTech,
Did you order the stock BPV or the Detroit Tuned RYEPHIX Bypass valve? and How can I order the RYEPHIX they do not have a Online Link to order. Thanks. . .

 

Detroit Tuned has them for $125.00

 

I got mine ordered by calling Chad (or/and Ryan) at Detroit Tuned directly...

 

Thanks!!
I will send them an e-mail today to check the shipping cost. Henry

 

cool! make sure to ask Chad for his "how-to".... It such a great hand for the install... I suggest your take 3 hours of your time, and get it done yourself. It will save your money, and it's very straight foward install.

But if you don't feel comfortable with taking parts out under the bonnet, get the Detroit Tuned how-to and get it to your favorite garage. With the how-to any good garage should be able to get the job done under 2 hours.

Detroit Tuned says it could hurt the fuel economy but I didn't see any difference and I still get 500km with a tank... I think I actually get more fuel economy than I had from my stock engine!

 

3 hrs. seems a bit much!! why do u say this?

 

I used Detroit Tuned to do mine by myself, and I did it in 1.5 hour.

But I was using a very good How-To and would had to figure how some parts would come out without it.

I guess 3 hours is the max someone can be charged for labor...

 

maybe a map sensor but it still has a wire like a maf

 

The MINI doesn't have any "wire like a maf" that can be contaminated by K&N filter oil. The only wires that a MAP sensor has are insulated and go between the sensor and the ECU. These wires don't come into contact with the intake air. Again, the MINI doesn't have a MAF. It has a MAP. The MAP is not affected by contaminants. If you have information to the contrary, please post it.

 

I noticed a change in construction for the latest version of the bypass valve. I have another failure and for this replacement I wanted to apply some slippery coatings but I encountered some snags. The latest version has stake flared T10 torx screws securing the butterfly. They can’t be backed out completely like the former slot head screws. When I tried to remove the adjuster set screw it split in half because it was super thread locked in place. It was as like tamper proofed. I had to settle for a file on the adjuster to reduce the butterfly gap. At least the torx heads didn’t strip like the slot heads. The bad one isn’t off the car yet for an examination.

 

Its throttlebody or harness to or connector to it.Unplug connector check pins put back in.Do this with ignition off.Turn ignition onto second position,let set for 30 seconds.Turn off wait 10 seconds then restart.Had same problem when I knocked connector installing k+n typhoon.

 

Damn! Add me to the list! 3000 miles outside of warranty too!

The ODB II code is P1688.

This is total easy to recreate. Foot on floor and boom at 5000 RPM! No power and rough idle until you shut it off and restart. Drive at 1/2 throttle and all is OK. Put your foot down and then it happens.

Dealer says there is a Service Bulletin on it. Cost is about $500-$600 to have replaced at the dealer! Time to find that how-to.

andy your pm's are full

 

He doesn't accept pms typically- he leaves it that way on purpose. He told me nicely .

 

ok..

 

Yeah, he likes to make sure that if someone has something to tell him, they must go off topic to do so. It's clever really.

 

Bypass Valve is now on National Back Order!

You guys with an '05 are having serious issues. Enough that my dealer has done a couple this past week and is now out of the part. They cannot get any more until MINI fills the back order.

Hopefully, they are out because they are redesigning the part! Also, don't expect a recall on it.

Limping around,

GMG

 

We have 5 in stock.
