Ok i hope this is posted in the right place but. to make a long story short i have a HKS BOV SSQV and i am not no I AM CERTAIN it is not installed correctly, and i have not messed at all w/ the stock diver valve, and i took my mini to the dealership for a "service" check up i tohuht it was for the oil change but it wasnt it was for the service, they checked out everything and everything was fine.
so i get home and the next day i start my car and i noticed NO pressure being released from the turbo i know THIS IS Bad so i cant drive my car, if someone could please help on this issue thank you!! im willin to take pics of the by pass valve and stuff, idk if that'd help but id just like some input on this. thank you

 

The car wasnt boosting or the diverter isnt functioning?

 

the diverter isnt fuctioning at all no pressure is being released from the turbo

 

trying to make sense of your writing is a challenge....but

you can start by removing the HKS BOV...its no help and completely unnecessary (and prob the cause of your problem)

then since you have an AP, using the live data logging feature to monitor the stock diverter valve...you will be able to see if its activating or not. Choose "BPV Act."

 

Under warranty still? Any OBDII codes to report? I would think there would be some type of message that described the boost going out of control

 

Wouldn't that have more to do with the internal waste gate not functioning properly? If the Diverter was stuck open you would clearly hear a hissing when your turbo spooled up.

 

sorry bout my writing, its hard for me to word things,
but i will remove the blow off valve, and i will try the Ap to see if it is activating or not thank you for the helpp ill let you know what i find out!

 

yes it is still under warrenty,
the only codes im getting is the code you get becasue of the downpipe, and another one but im not sure what it means.

 

i did try the AP and all it said for the BPV Act was off

 

Take the stock DV off and check the spring and the escution to see if they look OK.

 

ok i will take the stock diverter valve off but i am going out of town later today so i might not get to it untill i get back but thank you for the advice ill try that and illl let ya'll know what happens! Thank you!

 

What is the other code?

Well it will say "OFF" for most of the time, except when its being activated. For example, accelerate for a little bit then lift off, and it should switch to "ON", if it still says OFF during the throttle lift off...that is your issue.

 

The OP stated he isn't building boost at all, so it would be stuck open. it sounds like you have a turbo/waste-gate issue.

 

It's OK to drive the car without boost, it just won't have punch when accelerating. I assume you have an engine lamp on the tach?

Most likely there is a tear on the diaphragm (yellow boot) within the diverter valve. Remove the diverter, pull the face off if you can't see a tear from the outside easily. Are you producing more than 19psi? If so it's likely to happen again.

 

Don't see anywhere where he said that...he just said he doesn't hear pressure being released.....

 

IF a diverter valve is stuck open, you say it should make a hissing noise while spooling? How can you determine that sound from just the regular turbo spool noise. Sorry for the hijack, but i fear i might have this problem.

 

Thank you for pointing that out; I misinterpreted the "NO pressure" statement the first time read.


The OEM diverter valve won't stick in the traditional sense. The early model Forge BPV without the extra nipple can stick.

 

is the stock DV hard to take off i know its near the turbo.

 

i did try it with the accellorator on a bit but it still said off.. the other code id have to look at when i get back from out of town

 

the engine lamp isnt on jsut the check engine light but i cleared that with the alta AP.
i am not producing more than 19 psi although i wish. i am producing, around.. 15. but thats just with the reflash not a actual tune. my map that i have is stage 0. since all mini ecu's are different, they had to make a map for the AP to work in the first place. but i uninstalled the ap to see if it would make any difference, but it didnt so i reinsatlled it to do the BOV test.

 

oh nevermind bout the how to remove the stock diverteer valve i found a site witih pictures how to remove it,

 

Hay, if you are building boost, and when you take your foot off the peddle and you keep your boost, stop driving your car. That is a quick way to mess things up.

 

well i am not driving the car cuz i know that would destroy my turbo,.

 

ok so i guess my next big question would be what would be the proper way to get the HKS blow off valve to work, without havin the stock converter valve? i know there is a way there has to be!!

 

You will throw a cell, but someone out there makes a block off plate for the diverter valve. Get that and block it off. Then get the HKS, you should buy the exhaust depot hard pipe kit while you are at it.
