brought to the dealership and ofcourse the tech calls me back saying whats wrong with it. apparently its producing boost again... had no codes nothign i was driving around with no boost for like a week. my guess is the stupid bypass pressur valve is half working what do you guys think?


UPDATE: just incase someone has that problem someday, there is a little switch that the bypass presure valve opens on the supercharger with the little metal stick that sticks out, well that was seized by crap and rust so i used rust check penetrating oil and took a few house and then all of a sudden it freed up and now im back to normal on boost... STILL ITS FUNNY THAT TWO HOURS OF LABOUR at the dealership by the way Rallye motors in Moncton well he didnt notice a thing he said it was normal operating conditon.

 

no one?

 

or your car seena issue and limited boost, even ifit dont throw a code it can still save a code in the system. if nothing, then issue lies in the bypass valve or solenoid.

 

its at the dealership and they rand for codes and everything

 

k, sounds like u have a issue with the bypass valve or boost solonoid.Or possible got kr

 

now they say its working fine.... should i just buy a new one and replace it myself?

 

yes. unless u can diag your self

 

its just that it makes me mad it sould be under warranty but since its now working fine they wont change it.... ARGHHH

 

well tell them to drive it for 30 miles if it is bad itll usually do it. but reason they are giving you a issue is they want the issue you have to happen, if not it never happened.

 

bypass valve.

or solenoid.

 

WOW THEY ARE IDIOTS, the tech called me this morning saying that im gettin 20 psi on my gauge OMG my gauge is in PKA or whatever so im getting 20kpa ******* retard mechanic he was like is running fine.

man i swear i am so pissed off they always **** things up at that ******* place

 

hahhahaah i only laugh because I went to the dealership today and they are ******* retards too around here. They are retards everywhere!

 

so now i have to GO BACK TOMOROW and explain to the retard what a bypass pressur valve is

can someone show me what the solenoid looks like?


another thing i have to drive up north of my province saturday and if its not fixed will i dammage my car driving like this?

 

Ecotec Bypass Valve Solenoid 12633411 - Crate Engine Depot

Nope


HERE you go . ZZP is one of the only places ive seen that actually stocks them .

 

I got an 06 cobalt ss/sc and sometimes I'll get boost and sometimes no boost, it's on and off?
The boost needle stops between 0 and 20 kpa and usually it goes right to 60 kpa when I step on it. Does anyone know what the problem might be?

 

I say ure gauge is bad which is a known prob with the lsj boost gauges

 

does it feel not as fast?

 

Im going outside right now and do a little preventive maintanence and spray some lube on the bypass valve actuator( steel rod)
Thanks for the info!
