Have a look at this to see if it can help you in any way.......

 

Nice reply, Ambisaab!

 

now give me that program

 

I have the same code on my car right now, shop said that some kind of vacuum wasn't vacuuming and wanted $500 to fix it. He said it's not a single part, it's a kit he'd have to order. Limp mode sucks

 

Some related pictures in this thread:

This code has been on my car for a couple months and am now used to "limp mode" but is this going to damage my car if i dont fix it soon?

 

Where did you get this program? and is it available to the public?

Do i find the membrane from the Charger Bypass Valve?
Is there a part number for this part?

 

There are threads concerning bypass valve failure and repair for the 9-3. Specifically the bypass valves on the 9-3 Linear with the Garret turbo. If you do "thread search" (search 'bypass valve') you should be able to find ALL the info on this you need. It's a good/bad news situation. Bad news; It's an expensive part @ $300.00, Good news; very easy repair once you have the part.

PS- i bought that program ( called WIS ) for $2 on ebay. One the best buys I've made for my car.

 

Thank you very much! I have opened already the assembly.

 

Turbo Bypass Control Valve Circut Failure- Help! please!

Hi fellow Saab owners,

I recently took my 2005 saab 9-3 through NJ inspection and failed because of error code P0033. Ive researched this online and found that this code stands for Turbo Bypass Control Valve Circut failure. I have researched the part on line, but im confused as if that would even be an issue.

My question is really, if I order a replacement Bypass Controll Valve will this solve my problem? My concern is w/the word circut? Im thinking that this may be a totaly different problem, and replacing a part will not resolve this issue..

Is something like this a fixable problem by me?, or would I be better off finding a pro to do it for me?.. Of course money is an issue as I dont want to spend like 700-800 dollars through my dealer.

Can the guys here help me?....
Thanks in advance!.. Mike... Confused in NJ..

Wow old thread.... :lol:

Anyway it may be a simple bypass valve replacement that can fix it. But first I would check all of your vacuum hoses as that may be the only problem. do you have the big T or small t? (210hp or 175hp?) The reason I ask, if you do find out it is the bypass valve, the stock one is like $300, but I bought a forge after market one (that is rebuild-able) for $135 shipped, and if you are the least big handy its easy to install. its 3 10mm bolts to disconnect, and 3 5mm allen screws for the new bypass valve. Check out this thread upgraded bypass valve if you decide you have to replace the BPV. But first. Check those vacuum lines!

 

2005 9-3 Turbo Bypass Control Valve

Awesome thanks Saab guy for the response.. I currently own the 2.0t not the 2.0T... I will def check out the hoses before I do anything else, spunds like a logical place to start.. I do have a question though... I did a little research on Turbo Bypass Control Valves and I found an aftermarket part made by Bosch for $45 and the Saab certified for $75... This worries me because of you mentioning the price of the replacement part you purchased being almost $300... I hope im looking at the right part, the one I was looking at almost looks like a sprinkler head w/two spots for hoses at each end.. I will try to post a picture of what I was looking at, im sure that will help you a bit...

Thanks again for the help...

This is what I was referring too bypass valve Pic

Which can be found on this page at the very top Bypass Valve

But right now we only know that it works on the big T. There are some guys with the small t turbo that are currently trying to find a solution as well in the performance section. Good luck, hopefully its just a faulty hose!

 

Hey all, haven't been on this forum in ages. But it seems as if everyone is getting the same code. I have the P0033 code.

I don't know where the search feature went on this site but all I can find is information on the 2.0T nothing on the little t.

Am I stuck with the OEM option that is $300+ or is there any threads with any 2.0t guys successfully using an aftermarket BPV or even BOV. I checked all the hoses etc, all are fine, I'm sure it's the BPV.

Thanks!

 

I'm hitting this now with my 2.0t - so far my car has thrown the code twice and I am able to clear it on the fly via Scangauge (limp mode sucks!!) but I'm going to need to fix it. I'd like to go rebuilt if possible, since eventually I'll be upgrading from the Garrett turbo to the TD-04 (I should have gone with an Aero, dang it!) so I want to avoid spending $300 for a short-term fix.

Does anyone know the source (and part #) for the parts gator07424 mentioned? A $75 rebuilt is a heck of a lot better than $275-$300 for a part that will be thrown out by spring time.

 

Anyone? I hit a condition tonight where it threw a code, so I cleared it but I still had no boost until I pulled the negative battery cable for a few minutes.

 

Last year I experienced turbo flutter followed by P0033 and limp home mode. Pulling the negative would reset the code but the car would intermittently run right or throw the code again. I replaced (unnecessarily) the turbo bypass valve diaphragm from http://www.vivaperformance.com/mitsubishi-cbv-upgrade-kit/ because the problem continued. (Note that I have an Arc and did not want to replace the entire turbo bypass valve. This diaphragm does not work with the Linear turbo.) My old diaphragm was not torn and appeared to be in good condition as did the spring, but I replaced it anyway since I already had the new parts.

I then replaced the boost control valve (part # 12787706) in ctrlz's picture:

This solved the problem. The solenoid inside it was sticking and causing the code.

Do not rule out the solenoid as a culprit, especially if the turbo bypass diaphragm appears to be in good condition.

bumping this up. I am getting the P0033 code and replaced both of these solenoids ($100 total). Car ran great, had full boost back, but still major turbo flutter. ran for a week and the code popped up again. Would you think the next step is to replace the diaphragm (p/n 55558271)? I see kits on ebay going for $160, or single diaphrams for $80. do I need the kit or can I just replace the diaphragm?

 

Thanks, I'll try that. I have checked the vacuum lines and they seem fine. I'll pick up that valve at Shaw Saab (aka saabpartsusa.com ) tomorrow, and swap it out at the office.

 

Thank you for the tip - replaced that and the spark plugs (60K miles) and I have not seen the code trip again.

 

Three weeks have passed since replacing the solenoid and the spark plugs, and it has not thrown the code once. I have tried beating on it too - full throttle, let up, full throttle, let up at various RPMs and it's been perfect. Prior to that it was throwing the code regularly and in testing applying WOT throttle, backing off, and repeating at low to mid RPMs would throw the code consistently.

Thanks again for the tip - you saved me $300 plus a few hours' work (the screws on the BPV appear corroded and might not be so easy to remove). That $300 will go toward an upgraded turbo late winter or early spring.

 

P0033 - Bypass and check vales replaced - still have code

I have a 2004 93t - same P0033 code

I have replaced both bypass valves - THEY ARE NOT $300!!!!!! that is just madness, they are $25 here: http://www.goldwingsaabparts.com/product_p/12787706.htm
http://www.goldwingsaabparts.com/product_p/55354158.htm

anyway....I replaced both of mine and 2 check valves off of the EVAP hose and my car is STILL giving me the p0033 code.. I have scoured for a cracked hose but cannot seem to find one. Could this be fuse related? Has anybody ever found a shorted out wire? if so where?

Generally, there are 3 things that tick off the code. If you've replaced the two solenoids (the one before the turbo and the one after, @ $40.00) you'll have to replace the bypass valve itself (@ $300). It's super easy to replace. It's located roght on the side of the turbo. you'll have to disconnect a few hoses and then there's 3 bolts holding it in. You need to be careful when taking the bolts out because the valve has a spring held against the cover that will shoot it off if you're not holding it. After you've got the valve off it's a simple plug and play. The whole repair takes 20-25 minutes. the real blower is the that the simple rubber diaphragm on the bypass valve is what rots and its its $300. If your saab is after 2006 you've got a Mitsu turbo and you can find a cheaper replacement, if you're 03-05 you've gota Garret and you'll need to buy OEM

 

Wrong on the Garrett thing. Even in 03-06 the big T were Mitsubishi td04 14t turbos so not all 03-06 are Garrett.

 

That part# 12787706 is identical for both the boost control valve solenoid(on top of wastegate) and the bypass valve solenoid that Cntrlz's finger is pointing at. I ordered a boost control valve from EEuroparts and they sent me 12787706 in a bag labeled 55354158. These part numbers are interchangeable and work at both locations in the plumbing loop.

 

help please

i have replaced all the lines with silicone ones and my bypass valve is mint and i replaced the bypass valve circuit in front of motor the one above waistgate i believe its called i havent replaced but its has ben fine but im having battery issues also so can it be a battery issue or that last part i would need? or how can i test if thats the issue?

 

help

if you can just call me please its easier 6304785035

 

Testing these bypass valves for leaks is the same as ALL Saab bypass/hooter valves. Take a length of hose to the valves port and a vacuum source (it could be YOU). Does it hold vacuum? Yes? Its good. No? Its bad, probably has a hole in it. For the MY 03-05 little "t" turbos, I have a replacement diaphragm available.
