Finding a trusted mechanic at a reasonable price can be extremely difficult. https://www.youtube.com/watch?v=OBTyqrzXT8E. var s = document.getElementsByTagName('script')[0]; A mechanic must verify the code with an OBD-II scanner, then he should reset the code and road test your 2011 Saab 9-5 to determine if the Check Engine Light and the P0039 code returns. Definitely recommend him for getting the job done. if your thread has been sat in the Pit Lane for 24hrs+ after editing, pm Tech II to request release), IMG_3916.JPG [ 145.28 KiB | Viewed 1972 times ]. It feels and sounds like the turbo is building very little to no boost under a quick start at a redlight. Highway preformance seems almost normal but quick city driving seems not so quick anymore.. This is accomplished when the turbocharger moves impellers that are located in two separate housing chambers.

Raymond did a great job however I was charged for two hours labor and he was only here less than 45 minutes. While running the engine, gets the RPMs up to 5,000 and releases the throttle (uses a boost gauge to observe boost pressure levels). With YourMechanic you can skip the auto shop altogether. should I expect this on future appointments with your mechanic ? Dirt and fluids tend to collect in the lowest part of the intake system especially if near a very hot engine component like a radiator. Stuttering *could* be caused by over boosting and hitting the fuel cut out - maybe check that the 3 hoses on the BPC are also connected correctly. figured it out nowI didn't actually drive the car the when I removed the hose from the BPC the first time and only rev'd it in neutral and for what ever reason it must have unstuck something in the BPC if only temp. He explained everything to me in detail on what I needed to know about my car. Get a fair and transparent estimate upfront. Makes sure that the vacuum lines are not cracked, torn, or disconnected. View unanswered posts | View active topics. If the pressure is too high, an inspection of the bypass valve and a pressure test must be done. If an extreme drop in boost pressure is observed, this is an indication that the wastegate is not closing completely. P2261 (https://www.yourmechanic.com/article/p2261-obd-ii-trouble-code-turbo-super-charger-bypass-valve-mechanical-by-jamahl-walker) is the code for an issue with the vehicle's turbocharger bypass valve, also known as the wastegate. JavaScript is disabled. Users browsing this forum: markc4 and 6 guests. If the computer detects an issue with the wastegate circuit or signal it will activate the Check Engine Light in P0481 means a problem with the control circuit for cooling fan 2. The stock dash gauge is controlled strictly by the ECU. I hope to have more time tomorrow to test the BPV.

I have a engine problem which I would like to run past you guys.. Hey mine makes that sound aswell and does all the things you say too. When the car is cold there isn't really a problem and also when the car is revved from a standstill it is very smooth.and not misfire whatsoever. The bypass valve is either stuck shut or not functioning properly. Optional Photo/Image Link: (e.g. Board index SAAB Garage Workshop - Mechanical, Running Gear, Electrical & Servicing.

I wasn't sure if it was the little square black unit towards the left with hoses going down to the turbo. . Inspects wiring and connectors for shorts, burns, and corrosion, Clears the codes and runs the engine (if the P2261 code does not come back, it is an indication that an intermittent problem exists, which cannot always be diagnosed immediately), Makes sure there are no misfire conditions, Makes sure that the turbo hose clamps are tight, Makes sure that the turbo intake hoses and intercooler hoses are free from leaks and cracks. But would there be any other issues, considering that the TBV couldn't "open up" as it normally would when accelerating? owners, Over 25,000 topics, from beginner tips to technical Must have something to do with the Easter holiday. Message: (please no for sale/wanted classifieds - post those in the Saabnet.com Classifieds)
The second chamber impeller picks up cooler air from intercoolers and the turbocharger intake system and forces dense air into the engine. s.parentNode.insertBefore(ga, s); They do stick but I have found that judicious use of a flat blade screwdriver twisted at the end between the end of the pipe and the BPV seems to ease them back and free them. Was very courteous and professional. The impeller in the first chamber then turns the impeller in the second chamber. BPV? Link Title: (Optional) Highway preformance seems almost normal but quick city driving seems not so quick anymoreOther than that no strange leaks or smokeruns and stops normally with no bucking, stalling etc.
Kanstantsin arrived early. For a better experience, please enable JavaScript in your browser before proceeding. Boost pressure is achieved with high RPMs, and the engine cannot operate properly if boost pressure is excessively high or low (boost pressure specifications are determined by the manufacturer and programmed into the PCM). _gaq.push(['_setDomainName', 'saabnet.com']); Do a pressure test on the intake system between the turbocharger and intake throttle valve. Are these all the same thing?[/b]. var infolinks_pid = 3087885; var infolinks_wsid = 0; Hose and clamp failures are also a common cause of erratic or low pressure. for $114.99 P0253 OBD-II Trouble Code: Injection Pump Fuel Metering Control "A" Low (Cam/Rotor/Injector), Bolts between the turbocharger and exhaust manifold that are loose, Boost sensor wiring that is shorted or open, Boost sensor reference circuit connectors that are loose, disconnected, or corroded, Turbo failure caused by internal oil leaks and/or oil supply restrictions, Rattling sound coming from the turbocharger and/or turbo pipes, Hissing sound coming from the turbocharger wastegate and/or turbocharger hoses, Other diagnostic trouble codes stored along with P2261, such as boost codes, engine misfire codes, or knock sensor codes, Uses a vacuum pump to see if the wastegate is functioning properly, Replacing or tightening bolts between the turbocharger and exhaust manifold, Repairing or replacing boost sensor wiring, Repairing or replacing boost sensor reference circuit connectors, Replacing turbo or oil lines leading to the turbo that are restricted. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Yet, the car seemed to drive just fine, as I babied it homeperhaps unnecessarily. Will highly recommend to anyone.
