Just found this issue on our 2016 3.5l Transit 250. Easy to pull and check. Diaphragm was torn in two places!! Thanks for the help! Replacing with Ford part.

Sorry for your engine trouble but I’m glad the video helped you out!

Fyi. That part was making a clicking sound and it got replaced but the issue continued. The fix was that one of the clamps was loose, and it needed to be tighten in. That fixed my issue. Check all clamps.

This fixed my issue. Had a hole in the orange portion of the part. 30 mins to change out. If I had a lift it would have been 5.

Were you getting a squealing sound?

Thanks for the video 🙌🏼🙌🏼🙌🏼

I installed the Amazon blow off valve and it reduced smoke a great deal. I think there is residue in the converter and exhaust which hopefully will burn off eventually. I didn't find a diaphragm tear, but if you hold to your and listen to the sound, I think I heard a difference in while pushing the plunger. We'll see.

I have a 2018 accord 1.5 and I got the emission system problem light came on. I went to autozone to use the OBD reader and it gave me code P0299 turbocharger under boost. And recommended most likely solution: reconnect and or re-torque intercooler hose. My local Honda dealership told me I needed to replace the turbo charger. Now watching your video, could the fix be something else than the replacement of the turbo? Any feed is greatly appreciated

Absolutely. Underboost indicates that pressure built by the turbo is being lost somewhere - or, of course, the turbo charger isn’t creating enough boost on its own. So sure, the turbo could be the problem, but there are plenty of other places that you can be losing the pressure that could be fixed much cheaper if not for free. Check all places where air could be leaking after the turbo. For that matter, check areas before the turbo as well. I’ve just learned to seek out the cheapest and easiest and simplest possibilities first before replacing a costly part. Good luck! Let us know what you find out.

2016 expedition, 118k. kinda sluggish off the line, but has good power at higher rpms. No codes. I first removed the connector from the boost valve and found it to be full of oil. My suspicions is a tear or leak in the diaphragm which is not visible. Any Thoughts?

@williamtunnell

8 ай бұрын

Hmm, well this diaphragm is in a blowoff valve which lets off boost pressure when necessary. So the code throws when it leaks and won’t allow normal pressure to build up. The code, then, is an “Underboost”. The turbos are fine, but the computer thinks it’s not getting enough boost - because it’s not. With your issue arising at low rpm and no code, I’m not sure this is your fix. But for $35, it’s not an expensive experiment. My code would come in under load. Hard acceleration or towing. I certainly believe you should not be finding oil all over that valve, though. But I’m honestly not certified in anything!

Was taking off the old one and the bolt head snapped. Two questions: 1. Do you think it’d be ok to drive until I can get it repaired? 2. Is the solenoid something I could just drill new holes for and move slightly?

@williamtunnell

It won’t be good to drive it a lot without it, I believe, but if your valve is open you’ve essentially been doing that anyway. You won’t have to drill new holes, there’s actually 2 additional bolt holes. Thank you Ford engineers!

Would that boost /wastegate sensor cause p0299 cause the acceleration to drag almost w no gain but rpm’s to almost max out ? And only when flooring it when turbo should kick in and the motor sounds like it’s fine . I ran live diagnostic it didn’t hit over 5 psi in boost . I’ve change granny fluid oil and filter plugs bout to change this sensor today . The rear boost sensor had bare wires and oil on it inside ? I hope this clears the p0299 code tired of the headache. Ford for ya !!!

When your truck would throw the fault would it ever go into limp or de-rate mode? My torque converter is slipping and when I pull anything regardless how heavy or light when I hit any incline service light comes on and trucks goes into limited de-rate. I can shut the truck off then back on and de-rate goes away but the engine light stays on and it gives the same fault code P0299. Any input would be grateful.

So Terry, I had this exact same thing happen to me while getting the P0299 code. Ultimately, I had two problems. One was the part featured in this video, and the other was that I had to replace my throttlebody. No idea why, and very strange that both of these problems were happening at the same time. Nevertheless, the throttlebody worked and I’ve never had limp mode again.

Mine audi q5 2.0tdi goes into safe node only on highway slightly uphill after 40minuted or so. City drive no problems at all, whether you drive like crazy or normaly. But once you are on highway slightly uphill it goes into limomode. Po299 boost regulation turbo underboost. N75 and intercooler are changed. What could be the problem? I need help

Hello! I just had the code hit on my 2013 F150. I grabbed the Amazon part to put in. As I was taking the old part off the bolt near the wheel broke (it has more corrosion). I am going to try to rotate the part and use the other holes! Wish me luck. I just need to find another lag type bolt for it. I hope that is why Ford put the two mounting holes there. In hindsight i would have sprayed some WD40 or PB Blaster on it. Also, my old part had not obvious tear so we will see what happens. Thanks for the great video!

If it’s turbocharged, yes, it’ll have some type of blowoff valve to release pressure. It may not be the same design, though.

Yes, and you’ll want to read this. First, while installing it, it pulled apart; something I can’t get the OEM part to do. However, it popped right back together and seemed to function fine. I guess it’s just made differently but it troubled me when it came apart in my hands! I just reassembled it and installed it. Seemed fine. I got the code almost immediately - same day I installed it, and under no load whatsoever; literally just cranked it up and didn’t move. I cleared it and have never gotten it again like that. This weekend, however, I did get it again and it’s doing the same as the OEM part - check engine light comes on under a heavy load (pulling my 10,000 lb. camper) and during take off. It does not send the code pulling up to 70 mph, but only if I take off heavy - and only while towing. To be honest, I’m pretty satisfied with leaving it like it is - and deleting the code. It doesn’t effect the performance that I can tell. In short, after running it for a while now, I honestly don’t believe the Amazon part is any worse than the OEM part. Sorry for the length - but that’s the rest of the story.

@teenice894 I haven’t diagnosed anything further. It hasn’t thrown that code in a while now. I believe I simply have an air leak somewhere - probably a faulty connection. It only does it under load and whole accelerating. I think the turbos build enough boost to just push the air out somewhere else and cause the boost loss. It’s one of those things that isn’t bothering me, and you don’t notice any power loss so I haven’t worried with it any further. If it gets worse and more common, I’ll have to track it down.
