Does Your VW/Audi 2.0t TSI Have A Bad Turbo

[@PeaceLoveandMolotovs]

You hands down, have the best VW videos on youtube.

[@HumbleMechanic]

+ShotgunFelatio thank you .

[@spidusp]

I agree best

[@dermotricketts7099]

Were you saying the wastegate actuator is defective or that the turbo charger is bad? I was not sure. Which is it?

[@DFWJon]

@@dermotricketts7099 My understanding is that the wastegate actuator is part of the actual turbo. It looks to be on the hot side and I don't think you can replace just the actuator. I'm sure it is a bearing that starts to fail at which point it takes out the seal and then you loose boost. I think you have to replace the turbo itself as the wastegate actuator is not serviceable. You will need to double check my option as I am no way an expert, or even an experienced vw/turbo mechanic, on vw’s. I am a mechanic but very little experience with the vw and/or turbo chargers, in general. Hope this helps. Good luck and happy VW’ing!!!

[@Jamtastical]

@@DFWJonYou can replace the actuator and the wastegate. There’s absolutely no need to change the entire turbo.

[@pospc2]

Something I would like to mention. I had a p0299 code on my mk6 GTi. I checked for boost leaks and checked the wastegate rod. Everything seemed good. I gave in and sent it to the dealer( I don't work on many turbo VW so i thought it was best.). Dealer told me it needed a turbo. Which i agree. It was passing a lot of oil. I replaced my turbo with a nice new one. Still was getting p0299 and lacking performance. I did some data logging over a few days and all different driving conditions. I thought maybe I had an exhaust restriction. I took the o2 sensor out of the turbo housing(CBFA) and put a bore scope in. Saw the cat looked like a solid black chunk. Replaced the downpipe and checked for boost leaks again. This was months ago and the car is running great and no more p0299. While my situation was rare I wanted to put this out there for anyone who is desperately trying to figure it out and exhausted all other options.

[@HumbleMechanic]

Wow!!! Got call. They should have caught that when doing the turbo

[@aliceo6610]

Yes! Thank you very much.

[@simonshotter8960]

Was the blocked cat cashing the oil? I have oil build up going to my intercooler on a MK5 golf GTi.. I assumed the turbo was dying..

[@charlesbradley7987]

Mine was shooting same code. Couldn’t figure it out. Yesterday I went to start it and it blew white or gray smoke now there’s oil everywhere on backside of engine and car sputtering really bad. Still don’t know what’s wrong with it

[@psavel274]

The Wastegate rattle is popular, but in my experience, the actuator arm going to the diaphragm can get sluggish or even seized where it won't open as it supposed to making it sluggish/ wont return all the way to make it seal/ or get stuck partially or fully open. Best way is to just get under there and start looking . Good info for people who are unfamiliar with some of the issues that can plague these cars.

[@Will-jl9mk]

I just was test driving my 2012 GTI after replacing the intake manifold. When I got home, I checked the ecu for any codes, and this code was present. I opened KZbin, and without even searching anything, this was the first suggested video in my feed. Once my car is cool, I'm going to try this out. Thank you once again, Charles!

[@YotaguyJosh]

I’ve got a 2019 cayenne in my bay that I’ve been trying to chase the 299 on. I replaced the diverter valve due to leaking. It came back with the same code. I smoked it again and found nothing. I test drove and researched and finally found this vid. Needless to say, it’s getting a new snail. Thank you for the help. ✌️

[@theheaddon0909]

If you have a VW or Audi before 2014, p0299 can also be a bad diverter valve. The older ones have a diaphragm in them that crack and tear. Can replace with a newer piston version.

[@wasifshehriar3669]

But what if I actually hear the wastegate rattle while revving it in Neutral? Wouldn't be a diverter valve. would it?

[@nighthawkviper6791]

​@@wasifshehriar3669No that would be the Wastegate not properly seating meaning it's loose and rattling around. There's a couple fixes without having to replace the turbo, including the part itself on FCPEuro. There are clips for it too which help support the actuator too.

[@pospc2]

Would also like to thank you for your videos and response to my comments. I bought a 2013 GTI DSG for wholesale cost because it had issues(underboost,misfires,brakes). With your help I have got it sorted out and am still far below book value or even typical asking price in my area.

[@HumbleMechanic]

Awesome.

[@alexandrepankoski6636]

Thank you so much. I found this kind of problem in my Audi A3 2012. Took off the turbo and changed the axis of the wastegate for a brand new ones.

[@josecoreas554]

There are workarounds for the bad flapper. I pulled the wastegate, cut the arm, threaded a piece on the end to be able to adjust it and was able to fix the slack. Fixed the p0299 issue.

[@25musicmaker]

My VW Golf (1.4 tsi 122 hp dsg 165000 km.) went into fail safe mode on several occasions when driving on the Autobahn. After looking into the matter (vcds and checking the arm of the wastegate) I decided to replace the turbo for a brand new Garrett turbo. Costs : 500 euro and 2,5 hrs. of labour. Now runs like a new tsi again.

[@raiseray25]

Where did you buy the turbo from?

[@mbachman1]

Thanks for the videos! P0299 happened today. Slight tear on the inside of the DV. Will be crawling back under my car to check this tomorrow!

[@Vdub1910]

My brother has a 2012 Tiguan and he said he has a code for low boost and I think im going to to try this. Thank you Charles.

[@raysouth2]

[@GreggCesaroni]

I have used VCDS to for a boost leak check. I used to log and plot the values on a graph in excel versus the RPM. You also can see boost curves too for curiosity. And like you said, look for the specified and actual. I'm pushing 20.0 psi with APR stage 2+ with other bolt ons which potentially can cause boost leaks. They're all fine 2 years later. A big thing for those who have early 2.0 TSI engines, I believe 2010 and older, it's the diverter valve. Early engines had a rubber diaphragm that tends to rupture and you have no boost at all. I caught mine before it was going to tear. 2011's and newer got the revised piston DV. You can either do that, or keep the solenoid part and go with GFB DV+ if you're tuned (recommend it). You will get a fault code but it doesn't do anything and no check engine light. Holds boost very well and vents much faster

[@MaxCohagen]

hey man ! can i ask you for help? i have a BWA (2006) 2.0 tfsi engine......and after a highway round i get a whistle voice from the turbo side (i recorded it, bit.ly/2kiANPq , boost starts from 0.03 sec) . while the engine is "tepid" (not hot) i dont hear this whistle (and have 16-17psi boost, when the engine is hot i have only 9-12psi).... :S maybe is just a loose bolt? where the boost leaks? I hope there is no problem with the DV....

[@GreggCesaroni]

More than likely that is the DV. If you havent replaced it and you still have the original DV, it is that. I caught mine before it was about to tear. You can either to 1 of two things. GFB DV+ which is what I did, or get the upgraded Rev C which has the piston. GFB is for performance applications and works better. Uses the original solenoid. Rev C is an entirely brand new assembly. Pain in the ass to get to If it isn't the DV, check every single connection from the turbo, charge pipe, intercooler on both sides, then throttle body pipe. I would suspect the DV is the cause

[@MaxCohagen]

Thanks man! So, i bought the car as used a few months ago....but as far as i remember (when i checked the turbo) it has the original one.....i dont have a turbo related error code only p0441 (purge flow error). I was on a short test recently today, with a tepid engine and havent heard that little noise, and got the boost properly....around 16psi :S (dont you think that, if the DV would wrong i always should have a minor leak? in case of cold/tepid engine as well (?)) But thats true i also got an informations from my mechanic about that the earlier (2.0) TFSI engines has a naughty DV...and can able to burn or tear...because of the heat. maybe i will try to check the bolts and pipes/gaskets before....and if still have the psi loss with HOT engine, i'll take care of a new DV for sure. what do you think about Runtek DV+? www.ebay.com/itm/like/172439568818?lgeo=1&vectorid=229466&item=172439568818&rmvSB=true Its just 38$....maybe its a fake? :S

[@GreggCesaroni]

MaxCo I wouldn't trust that DV lol. Seems like it's a knock off version of GFB. Either way, I would just go with the GFB DV+ even though it costs $130. I've had it for 3 years and it's never given me issues. It does throw a code because of the stiff spring is uses. P2261 or something like that but never throws a check engine light. GFB said if you want to eliminate that code, remove the spring but you won't get the performance benefits of the DV+. It spools up much quicker, holds boost better, and releases boost much faster than stock. All the VW techs at my dealer know about it if my main tech isn't there which is rare. Besides. I'm holding 20-21 psi with mine no problem.

[@GreggCesaroni]

MaxCo I also have a 2010 with the earlier CCTA engine so yes I know all about the DV going bad. I could see a line in the rubber diaphragm where it would've torn. Also, do you have a boost gauge? That's another cause of boost leak too. The vacuum block adapter that goes on the intake manifold.

[@Jushwa]

Our previous Tiguan which was a 2010 had the turbo fail at around 110k then the timing chain tensioner at around 11400. Which basically damaged the whole engine, cost to repair was going to be around 8000 CAD which was about half the value of the car at the time. However, VW covered 70% of the cost for parts damaged by the tensioner failure, because the car was out if warranty by only a couple of months, and because of customer loyalty. It was disappointing to say the least, but it didn't deter us enough from getting another.

[@shadyali-ze8or]

How did you get VW to cover anything being out of warranty ?

[@jayrey311]

Hi Charles. I really enjoy watching the video blogs/how-to's for both VW and Audis that you make and as well as Paul. I am new into the VW/Audi family as I have picked up an 06 A4 B7 2.0T FSI. Since picking this vehicle up, Ive been have all sorts of problems. from overboost, to underboost, to cyl4 misfire and other Pcodes that I have seen.I have replaced the TurboCharger with an alternative brand as my old one (WG flapper) assembly was wobbly. Ive ran a boost leak and tighten all pipes,etc.still having the issue. ive replace the diverter valve with the updated version and even purchased the GFB+ and swapped it out with a new DV and then a hybrid BOV. I even replaced the N75 with latest rev. Ive cleaned the gunk out of the intake. replaced the cam follower and also vacuum pump. replaced most of vacuum lines. inspected the BSH revamp delete kit. replaced the PCV valve. What i do notice is that when the engine is idle, i can hear a slight hissing sound but unable to pinpoint it. no leaks from valve cover. there are many times it can only boost at or barely 5. but if i were to start the vehicle in the morning, the car can exceed 5 ~ 15ish @ avg 4.5k rpm. There's also this hesitation when accelerating (it does feel fluid). The car has about 186k miles. compression is at (i might have to use another compression tester) cyl 1~ 3@ 115 and cyl4@ 91. No blue smoke from the tailpipe. car also has an APR stage one ecm upgrade when i purchased the vehicle used earlier this year. someone told be to swap it out with a stock computer to see if the apr upgrade has something to do with it. I do have an obdeleven that i purchased from Paul at www.Shopdap.com and have used to the best of my ability to check the codes, email them and clear em. I also have a boost gauge in the center vent but have not traced it where its connecting to. though one thing i can say is that there is this small vacuum hose that is connected to the intake manifold and reduces the hose to a size similar to 1/8 ID (?) and then connected to some see through inline filter and then connected to a barb fitting and then it is fed through the ecm box. From there Im not sure where it leads to. I really dont want to give up as I have invested alot of time, sweat (living in vegas), long late nights away from the fam while working in the garage. Any suggestion(s) is really appreciated as i would love to get this vehicle back to its glorious state. Cheers, Jason

How might you propose installing something like this with the car on the ground. Thanks, Charles!

I had an underboost fault lately in my 2017 1.6 tdi vw golf mk7. Checked the codes, even glow plug error jumped in alongside all of the turbo underboost ones. It turned out to be a single small hose that got disconnected. The one just over the turbine. I cut and shortened it and slid it in and suddenly there was no error anymore. I think I will replace most of the hoses, tubings on the engine in the near future, cause even thou they arent that old, more and more problems start to occur related to these.

All my other sensors were pretty new except this one and didn't even expect a fix when I replaced and everything was fixed. Before expensive parts I recommend trying the sensors. I apid for a shop diag that didn't even mention sensors and luckily tried it on my own. I've driven it hard even at full throttle multiple times now and no engine lights weird noise so far. on the new sensor. Power and torque all feel great. Wish I'd replaced the sensor 50k miles ago.

I have a 2006 2.0TFSI has the same code. Replaced a turbo that I know has done 90,000 miles, car was great with replacement "Ridex Turbo". It lasted about 4 months and the code returned along with a rattle. Figured the turbo was good so changed the DV to a REV G and the car was slightly better but still had P0299. Took it to a mechanic and turns out the wastegate had fallen off and was rattling around inside the turbo. New Borgwarner unit being installed by the shop.

There's no such thing as just get a better turbo this drivel is such nonsense without painting the entire picture. What's required to SUPPORT a better turbo upgrade where you can drive on an unrestricted road and top out at insane speeds because of that supporting ECU upgrade and 3" DP upgrade and the Full Catback SS 2.5" or 3" Exhaust upgrade and the Upgraded DV with accompanying Boost gauge and the Transmission upgrade with the Upgraded Clutch Kit and the Suspension upgrade and the Brakes and Brake lines upgrade.

Hi Charles like you said I got a Tiguan with the same under boost fault and it was loose on the waste gate pivot I installed the anti rattle clip that you can get at the VW parts department it's meant to reduce the noise from a loose waste gate but I installed it and it did solved the under boost for a while but the other day when the customer came in for a service there was a fault for low boost but at least it's way better with the clip on now what I do is on all CCTA engines I install the clip before the the problem is there I think that it will help prevent the wear of the waste gate there is an other thing to look for is the cut off valve on the turbocharger if the car is a early production it might have an old style valve with a torn diaphragm I've seen it before the other day I got a Jetta with this fault and the hose close from the throttle body for the sound generator for inside the car the spring clip was left off when the dealer replaced the injectors on warranty.

hey Charles, couldn't you just purchase an aftermarket waste gate acutator with a threaded rod and adjust the preload tension rather than the entire turbo? it seems that the wastegate flapper would still seal, just that the original wastegate has worn quite a bit causing it to lose its preload tension on the flapper when shut.

[@MaxCohagen]

I have a question if anyone can answer it, the "whistling" sound that he's talking about does it sound like a clean whistle or not? Mine makes what I would describe as rustling leaves noise. Is that something else I need to look into?

[@leovideo121]

Please help with the Turbocharger Cooling Pipe how can i replace it? is there any video?

[@muggins57]

My 2014 2.0 TSI Tiguan displayed the P0299 under boost trouble code with 45,000 easy driven miles on it. Took it to VW dealer who informed me they found a loose waste gate. They are going to replace the whole turbo assembly. Apparently they are not willing to repair the waste gate alone to save customers money on the repair. This is an expensive repair on a low milage car!

[@jacktaylor1073]

My scirocco sounds like it rattles/ticking but only when letting off the throttle. Not at idle or steady rpm. Idk if this is a problem or not, no error codes

[@ralphbell6281]

Would the waste gate clip that's sold by some time or a waste of money?

[@addio1226]

MIDLEADING INFORMATION: You can get the wastegate actuator replaced or send it somewhere where they rebuild turbos (way cheaper than dropping over $700 on a new OEM turbo). Also you forgot to mention to check play on the turbine if it moves in and out. Also spin the turbine and if it feels like it hits something, then it’s bad as well. One last check is really easy, run the car hard (pedal to the medal) for at least a good 30 minutes at night. Then park in a dark area, open the hood and check the catalytic converter. If it’s glowing red hot like if it’s lava then turbo is leaking oil into the exhaust system and intake system. You can also smell the burn every time you do a hard pull. You don’t need a new turbo, you can get it repaired/rebuild. You can even buy a good used one. One last thing, expect the life of your turbo to drop drastically if you run a Stage 1 tune or higher. Hopefully this helps someone

addio12 this guy’s calls himself humble mechanic. And “likes vdub” but all his videos are him talking shit on them and making claims for videos.

[@HumbleMechanic]

I’m not sure that’s accurate. Or has anything to do with humble or not.

Hey I have a 2004 Audi AT 1.8t and last year I upgraded to the K04 turbo with software upgrade, injectors, and high flow CAT. Everything has been running great and still does, except about 6 months ago I noticed my exhaust manifold and turbo housing getting red hot. I mean literally glowing. I used my infrared thermometer and it read 900°. I know turbos are meant to withstand a ton of heat, but what could be the cause of this? Again, no under boost condition. Should I get a high flow exhaust manifold?

[@matttorian]

@@dillonclark7737 Could be normal or it needs more fuel to cool it down. Prob get a air fuel ratio sensor installed and make sure its in specs.

[@harrynazarian3184]

Dillon Clark, you're probably running too lean. What's your AFR when under load going through the RPM range? And did you get a proper tune after the upgrades to your injectors, turbo, and high flow cat? How about your fuel pump? Is it able to keep up? Finally, how big are your gaps on your plugs? Bigger gap means bigger spark means hotter burn (potentially)

[@alextorkelson6261]

Some 1.8T movies would be excellent. Maybe a video on diagnosing water ingress on the B5.5 Passat? Seal along the window, sunroof drains, battery tray area drains, and finally, the pollen filter tray.

[@VektorHaus]

I have a 2007 Audi A4 2.0 Quattro, this is the 3rd time in less than a year that I have replaced the DV and I still get the P0299 code. What I think that makes this unique is that when the car is running cool, it's a beast! But as soon as its up to running temperature its pure sluggish. I notice that when the P0299 does come on its usually on some type of incline (me going up hill), or merging on to the highway. I hit the gas and it doesn't do anything. Again when its cold, its a beast. But as soon as it warms up this happens. I have been finding multiple answer for P0299 , MAFS, PCV, Cat, this video. But Im thinking that the temperature issue might help diagnose it further. I read that it could be a leak somewhere because of the metal expanding when its hot. Still not sure. Oh and after an oil change at about 3,000 miles i get a low oil light. and then I add a quart. Please help if you can. I love the car and it normally drives great, but this acceleration issue is a pain in the ass. thanks again!

[@MaxCohagen]

similar issue here....i have a 2.0 tfsi leon. I have around 16-17 psi with warm (but not hot!) engine...but it drops to 9-12 psi after a 10-15 mins highway round (constant 3500-4000rpm). otherwise i dont have an error code for this, but after the highway round i hear a whistle voice/sound from the turbo side...so i guess i have to tighten the bolts on the exh. manifold (so there is a boost leak)....but you cant tighten them on cold engine :/

[@ivangsvts]

Hello Charles, I´m writing from Ecuador. Thanks for the useful videos you publish. One quick question, would you advice to buy a 2.0 tsi or 1.8 tsi equiped car? here I have a couple of options with very low mileage cars. Both passats 2014 with less than 40 k miles! I own a skoda octavia tdi and I have changed the turbo twice already,,,, thanks so much for your time and answer!!

[@pospc2]

I got an unusual cause of a p0299. Restricted cat. Not fully clogged but restricted. I actually replaced the turbo based off what the dealer told me and still same issue. I have a cbfa and took out the o2 sensor on the turbo and hooked up my vaccum/boost gauge that is connected with a couple adaptors and started the car. At idle it was 2 psi reved a bit and went to 8 psi. Edit: forgot to mention I only had a p0299 code and nothing else.

[@gamersroost]

Longshot here, but could you explain why someone would get a hiss sound until the boost is built, then no hissing until you get off the boost?

[@gamersroost]

I had boost leak on my hot side charge pipe and the cold side from the intercooler.

[@marcbridge9098]

I'm throwing a p0299 code but my A3 8P is running fine. -8 to -10 PSI Boost at idle and stomping on the accelerator results in a +16 with no noticeable additional lag. Doesn't seem like there's anything wrong. Could anything else trip that code?

[@leoreyes4848]

I just got this code and I really hope it's a diverter value and not a bad Turbo.

[@HumbleMechanic]

Me too

[@leoreyes4848]

@@HumbleMechanic Yo ,it was the diverter valve, put in a gfb T9351 ! This thing make the car so playful!

where can I buy an affordable turbo replacement stock turbo for the MK6 2.0 TSI

[@jahonlouie]

Do yourselves a favor and upgrade to a turbo with a separate wastegate, unlike our integrated one. Mine was bad on my 2013 Q5 when I bought it with only 33k miles on it about 4 months ago. I thought, “wow, great deal, low miles”. Luckily, I felt something wasn’t quite right and heard a clicking on low boost acceleration while going up a hill and it was covered by the dealer under the 30-day warranty. I had no warning lights or codes in VCDS yet, but I’m sure it was only time before it started causing major issues. No oil consumption luckily, but I think it’s less prevalent on the facelift models that support e85 since they have larger seals. I guess we will see. Changing my oil, AT LEAST, every 5k to be safe.

[@danielnelson8304]

"BAD, TURBO...BAD!!" *swats it with rolled up newspaper*

[@andrewelliott515]

Perfect explanation and demonstration! Thanks for your videos and keep it up! :)

[@Kranium31]

There is a video on this repair. Just search do a quick search. It does look pretty straight forward.

[@MotorHeadTech]

wastegate is fine, my boost gauge psi is normal, but i am getting that engine code: p0299 & another one which is "turbo is underboosting" and " turbo boost pressure not detected" and this all happened after my 2013 audi a4, decided to leak oil from the valve cover gasket (technically sealant) & timing cover gasket. which i fixed but now i have this rough idling (extra sound & stress on my engine) & now my car is running in this limp mode where my horsepower & throttle response is delayed & slowed down. help??!!

[@randomuser-n8i]

I work at a VW dealership just did a turbo on an 11 Tiguan with 36,000 miles, same code found turbo bearing to have completely failled and destroyed the fins. Similar one also failed at 86k 2016 Tiguan.

Hey I have a 2010 Volkswagen Passat 2.0T and it lags and sometimes won’t go in reverse and when it won’t it’ll make a weird sound as if it’s changing gears or something is that bad transmission? Or would that apply with this

[@GunnyNinja]

Can't this be fixed with an adjustable actuator rod? Instead of hammering them like some do?

[@lequ1152]

On my 2007 Passat P0299 was actually caused by a misfire because of a bad coil pack

[@daltoniks]

Vw passat 2.0 TDI 2007.... 008825 - Leak in Air Intake System P2279 - 006 - - Intermittent - MIL ON 000665 - Boost Pressure Regulation P0299 - 006 - Control Range Not Reached - Intermittent Car can't move more then a few cm, then dies. Idles normal. Turbo apparently is stuffed. (previous owner said). How hard is it to check that turbo before even trying to remove it. (is the removal process complicated for someone who is just mechanically minded person)?

[@freshwatermechanic]

Have you seen a turbo on say a 2010 cc blow a turbo seal an bellow smoke from the exhaust as well as leak from exhaust side? Will not over heat but lots of white smoke an oil in exhaust

[@David-uu8vz]

Could this fault be intermitant ?? Car drives 99 times out 100 but every now again it just looses all power could this problem just starting to develop

[@artybrandt]

So on my 07 A4 2.0T I got scans that read misfires in cylinders 1 & 4 as well as the turbo being under boost. The cylinders misfire around 4000 rpms, would the ECU cut boost when it reads a misfire?

[@focusedrevenue3541]

I don't have this code. Only code I is crankshaft and camshaft. But I do have white smoke. Would you have any idea what is could be? Thank you in advanced Love, the videos have helped a lot.

[@johnjunior22]

Hi i just got a 2007 VW Passat 2.0T I accidentally put regular gas in it. The check engine light comes on and after a free diagnostic test from auto-zone the code is P0299 Turbocharger underboost . I don’t know if I have to check a mechanic shop or refill it with premium.

[@HumbleMechanic]

I doubt those things are related.

[@aamir1913]

Dear HumbleMekanics I have this error code p0299 on 1,9 tdi. It drives fine normal on city but on highway after 65 mph it come with spring light and engine light message. But if it’s work in city is my turbo bad or component of my turbo!!! Thanks 🙏
