Dude, from one Professioanl Technician to another I extend to you many many thanks yous. I have a 20 year old Passat 1.8T and a 2008 Jetta 2.0T FSI and whenever I VAG my rides and see an issue I always go straight to your channel... I gotta say both engines have been flawlessly running in reality... I got my 1.8T from a retired doctor in the city and she only had the VW dealership ever touch that car so it was squeaky clean inside the engine and I'm running Rotella T6 in it and it LOVES that oil... My 2.0 has had a few issues like this one here but it's been a rocket on wheels and never left me stranded. Both cars now have over 350,000km on both clocks and the run perfectly. I attribute a lot of their good vibes from being able to save sooooo much diagnostic time by going straight to your channel... again many thanks from up here in Canuckistan!!

Great info! Wife's '08 Eos just threw a P0299 code today. Glad to see the fix is relatively simple. Just a couple questions: how does oil get into that area? Is the turbo lubricated via the oil-pan? Just seems odd that oil would leak out of an intake area. Thanks.

@Kevinalvesmusic 7 жыл бұрын

Quick question I just installed my new Turbo DV. I noticed the o ring though. do I need to lube that with bearing grease or something? What would you use? Or do I need anything at all? Also should I use lock-tight on the screws when putting back in? Thanks so much!

@enemy2921 4 жыл бұрын

I never had P0299 code but suspected my turbo diverter valve was damaged, and knew it was the old version of the part. When I took the old diverter valve off I suspected the rubber diaphragm would be torn like my PCV was. BUT it was fully in 3 pieces when I finally finessed it out. Glad I got that fixed its driving much smoother. Now to get those dirty valves cleaned...

Humble mechanic what are your thoughts about gfb dv+ ? Is this finally the best solution for both tuned or untuned cars?

@TheArizonaAssasin 6 жыл бұрын

Thanks for another great video. Do you think it's possible that oil in the DV connectors could cause a CEL and throw the P0299 code because the oil caused an electrical fault? I ask because my CEL has turned on 4 times in 6 weeks. I've replaced the PCV, the boost sensor, fixed a boost leak, inspected turbo and my car still got a CEL. So today the mechanic changed the diverter valve because there was oil in the connections. I'm just afraid of the CEL coming back on because all that's left is the turbo but the car runs smooth as per my KZfaq videos. If I'm reading this service bulletin correctly, a diverter valve with oil in the connectors can trip the CEL with a P0299 but I wanted to know what you thought regarding that as a possibility. I've run out of things to fix with the P0299.

@Lumlums 6 жыл бұрын

I unplugged my connector and a bunch of oil came out and when I removed it, it had no tears. And I have a p0299 turbocharger under boost light. Do u think this is the cause to my check engine light? It still build boost fine. Peaked at 15 psi the held steady at 10 psi. Also I have an Audi A4 2.0t B7.

It also suffers from a shake at idle which I can see to get right and when it's first started in the morning I engage the clutch and it jumps jumps as if I'm wheel spinning lol then won't ever doing again all day but clutch flywheel everything seems fine so I'm suspecting on the lines of injectors or fuel temp sensor 🤔 hope you can shine some light onit 😅

hey bro. I have an 05 a4 at my shop with the 0665/po299 code . haven't messed with many turbos so pardon any dumbness. I also had a 300 and a 301 in history. definitely gutless first test drive. and big gap in my charge values. I pulled the valve and see no tear but oil poured out of the plug. cleaned everything and put back in. then it misfired bad on no1 on next test. pulled plugs and all are dark but have white crud build up . definitely burning oil. with a fresh set of plugs it ran better and boosted once , charge values even at 1600. then I romped on it .. blue and black smoke bad. shut it off and restart 10 min later and Belched a building sized blue cloud. oil in tubing before throttle body, but also hisses and runs rough when I pull the oil cap off. I'm thinking I have turbo and pcv issues but wondering If u have any other testing advice before I scare the customer into trading it in

Can the diverter valve be in such bad shape that I get almost no boost until high rpm? The turbo spools way faster than it should barely pressing the gas and is pretty loud but the power just isn't there. I just picked this car up and fixed the terrible multiple misfires and it was running great for a few days now it's doing this. I am very mechanically I just have little to no experience with Volkswagens. Any help would be much appreciated

Is that a Diverter Valve issue or something else? No codes have been thrown to help hunt down the cause. Manual transmission, clutch engaged throughout the transition. BTW, always find your videos valuable. Thx for your advice.

So I installed a cold air intake and my car ran fine for about a week. Then I noticed my car was only Boosting to 5psi. I am tuned and I hear a weird noise when my car blows off. I feel a lack of power and was wondering if its the Diverter valve? I am not throwing any codes (yet)

Hey HumbleMechanic, I always see people on vw forums upgrading the diverter valve to a DV+. What does the DV+ upgrade do?

Do you have experience with any of the aftermarket ones made by performance companies? Is there any reason to get one of those on a tuned car over the latest revision?

Stratton Yatron If you are tuned, I would add it to the upgrade list.

HumbleMechanic Thank you for your reply, it's only APR stage 1 91 but I'll get one before adding any more power.

I keep getting lag and after lag I get cloud of smoke. Could a diverter valve be my issue?
