Jonny and Jon both encounter low boost trouble code P0299 on two different cars, a VW Tiguan and an Audi A6. The problem is the same for both cars and cannot be repaired. Both cars require complete new turbos.
I solved the Turbo issue by buying 2005 e90 325i (N52) with NO TURBO :) And as this is the last engine with indirect injection, it solves carbonization issue as well - for free! :)
We just went through a streak of these. Seems like it always goes that way. I've only done a few of these on longitudinal engines. Transverse seems a little tighter. We use these old turbos as door stops. I've considered saving them up and welding them together into a sculpture.
Yeah super common issue, the part is built like trash unfortunately, and the way you have to replace the whole manifold like that - this is absolutely engineered obsolescence in action. Just shows what a crowd of evil bastards VAG are.
Yep, super common problem on those engines! It's happened to a couple friends of mine in fact. I've heard that it's about a $5k job at the VW dealership.
Original turbos from the manufacture are about $1-2,000, labor should be about 4-6hrs. Shop labor rate varies. Save to say it’s a $2500 dollar job. Extended warranties cover these repairs.
It seems pretty mad you have to swap a whole turbo just for the wastegate. Like Jon said this is pretty common on some BMW's but can be fixed without a whole new unit.
Well the thing is, you want to warrant your repair. You can fix the play but it will be an ongoin issue. replacing the whole unit is the best way for customer and repair shop. BMW and Mercedes also have this problem
What's even more crazy is the owners replacing the turbos with...another same factory turbo. I never understood this for a minute but see it all the time. Might as well get a K04--not much more money for a kit including tuning, and you get a *ton* more power as a result. Also K04s usually have the adjustable wastegate arm with the threaded part and the nuts on the end.
Good to see Ninja using fender guards in case of minor scratches , young mechanic with beard should take note...customers car protection as best to their ability : )
I had the same code in my 2006 A4 quattro 2.0TFSI. RU-vid showed loads of videos saying its the wastegate. So I bought a NEW turbo. Got the old one off, wastegate was tight as anything, could not move it at all. The compressor wheel had about 0.5 - 1mm of forwards and backwards play, 0mm left n right. When the turbo was being removed the nuts holding the exhaust manifold to the block were all loose. Only the middle one actually needed to be cracked off. I've possibly done 90k miles with it like that an not had any codes. PCV was changed at the same time, but with this new turbo my car has the power is should have had. Possibly it could have had the same result if we had just tightened the bolts, but ill never know now. The old one does seem to have a crack in the wastegate housing, so fitting a new one was probably a good idea. 155000 miles and the car pulls like its new.
That fault code can actually pop up for a faulty MAP sensor that is STUCK LOW, and the OVERBOOST code for one that is STUCK HIGH. Check THAT first everyone. Live data with a scan tool will verify.
You still need to do the labour to remove the assembly...down time while machine shop has part...no warranty on the part...reassembly of everything...and then what cross your fingers? Best solution is not to buy German Junk period. Labour is expensive. Lease these pieces of crap and give them back...or don't buy them period. You can't fix stupid.
@@rwd323 I know, but checking for bad MAP sensor first is easier than taking turbo out. It is sometimes a simpler fix. If the MAP is fine, then by all means check wastegate. But then again, I'm a logical guy. Logical troubleshooting is a dying art in these days of parts changers like these guys.
It isn't logical to assume that you know what did or did not happen beforehand. This problem was fully diagnosed as being the waste gate, long before the new part was ever ordered. The video only focused on the actual problem.
Whenever i get these engines with a mil on i rev the engine to about 4k and release if its bad you will hear the metallic rattling, easy way to know before scanning
I have a similar waste gate issue in my '15 Mini Cooper Countryman S ALL4. Is there a particular manufacturer or type of turbo you would recommend to replace with? Or is this just the nature of the beast and any replacement would likely eventually fail in the same way?
its also due to poor maintenance. many people just drive and dont care about anything. But these cars in europe run 300.000KM relatively easy with no turbo replaced at all, but they get maintained well.
I also believe german cars for the euro market are much better made than those for the american market. Remember that americans change cars every 5 years at least. That could be a thing.
Do I smell a sponsorship?! Or at least a job in modeling?! (Funny how he wouldn't even waste the NOS pouring it on his face and used water!) LOL - He REALLY loves his NOS!
Would just bending the rod with a wee bit of heat be a quick and dirty way of taking up the slack in the wastegate rod... maybe spacing the wastegate actuator with a few washers too.... or even better, weld it closed!!! AND ADD NOS!!!
I have the B9 2.0T. I tightened the wastegate to the point there is zero play, but it won’t come out of limp mode. I’ve unplugged the battery, taken fuses out, and tried all the tricks. Next step in using an OBDEleven
Not only do you have to replace the turbo for a small problem but the new turbo has to come with the entire manifold. VW Group cars are not meant to be used without warranty
Yup he’s exactly right by saying that, and little so they know, they can bend the line in an s shape and problem is solved, I’ve done say at least 40 of these engines, never once replaced a turbo
@@aldinnukicic3458 I seen some guys wedge open the wastegate then heat up that wastegate arm with a torch and smack it with a hammer bending the arm just enough so that it closes tight after that.
Isnt it a good idea to be sure the oil line to the turbo is flowing 100%? Asking because another channel had a customer who had their turbo replaced by a different shop and it failed due to lack of lubrication, he had to take the oil supply line out and replace due to it being clogged
In America the hourly rate is more expensive than the replacement part. So fixing the waste gate on a used all in one turbo, manifold, waste gate is most likely more expensive than getting a new replacement part.
These are electronically controlled turbos. As you can see by the electronic servo. Repairing the waste gate is not available and is not advised. So no repair is available then no repair is given. Only replacements. Most of those cars have extended warranties. Not everyone is gonna be footing 2k shop bills for a turbo especially since they just got a timing chain service done on it a month ago that timing chain service alone is about 2k -3k service on a Audi A6. On a 2014 A6 that’s about 20-30% of its value in a month
The 2015 Ford Explorer turbocharged four cylinder has the exact same problem. Problem is when trying to buy a new turbocharger nobody has them in stock, not even the Ford dealer. Very poor design, should be a factory recall in my book.
So my 2017 Tiguan under extended warranty just threw this code and supposedly they removed the turbo and sent it off somewhere to rebuild it with a new waste gate???? After watching several videos of everyone saying just replace the turbo I don’t think it’s going to last too long if they’re just putting a new wastegate on 😂 But I’ve got a few years left of warranty and I’ll definitely be selling the vehicle before it’s out of warranty hahaa
Need help; 08 X5 N52 hesitates during acceleration, no engine light, checked all coils spark plugs, vanos, new oil, new air filter, cleaned maf sensor, checked valvetronic gasget, and still not fixed
what about just cutting the the rod, threading it and put on a connection nut with lock nuts ? cheap fix for a simple problem ? probably not a lot of space back there to do that though
Wouldn't it be nice to have designed into these parts the ability to repair them, not just throw new parts (manufacturer engineers and bean counters...hello?). Looks like you've created a fun place to work Jonny...nice! If work is fun, it's not work anymore.
Notice they have el cheapo aftermarket coils too. So customer must have been having misfire fun before the wastegate gave up the ghost and whole assembly needs to be done. I wonder if they will trade for another VW. Probably.
Two gorgeous Mercedes in the background... That 2001 clk 430 and the cls63 or 55 not sure but classic Benz designs. Those turbos are so annoying and unreliable. But now from what I've seen, they make them a service friendly. Turbos are in front so "easier" to remove and replace. Still hate them. 😡
Why wouldn't you cut the rod in half, cut a bit out say 5-10mm , then cut opposing threads in the shaft and fit a socket with opposing threads like a turnbuckle and then shorten the rod. It should then last for quite a while. How much does a new turbo cost ? Must be over USD 1000-1500 .
So it seems that VAG turbos aren't all that great ;) Do the new ones have the same waste gate design or have they modified it to allow future adjustments?
the problem is that VW or Audi don't made any turbos they are made by IHI , GARRET, KKK, or Borg and Wagner it's up to the supplier to produce a reliable system but sometimes they don't get it right the first time and that's a shame the customer has to foot the bill. I remember when I had a audi S6 with the 5 cylinder engine the waste gate was a pop off type and it was servicable and reliable . but it took more space . now VW is going with a VTG turbo a the 1.5 gas engine this could be bad of good we all have to wait to see if it's going to be reliable.
@@audikris Your right about damping the vibrations. The vibrations are what actually cause the failure. They cause the shaft going into the turbo to wear out the bushing inside.
Engineers signing off on a turbo design with a common and simple moving part unable to be serviced, adjusted or repaired without replacing a major component of the engine… either that’s incompetence or built in obsolescence… take a guess which… scandalous when you think about it…
Great German engineering can't even engineer an adjustable waste gate shaft got to bye the entire tubo can't you get a turbo reconditioner to modify it
the shaft assembly becomes "loose" from poor design...and they require you to buy that entire assembly 95% of which is not required to fix the problem. Brilliant...well obviously for parts sale hustle.
Most VW/Audi vehicles that I know of that have this turbo issue usually are on "tuned" vehicles. You crank up the boost, the OEM stuff just won't last. These are things people don't think about when they do a simple "tune". You Pay to Play 😎
@@gasolara2002 not sure if that is true or not... One thing I do know... Once you go forced induction very difficult to go back to NA. SLOW is the first word that comes to mind 🤔 Though I will admit my Dad's 60 bug convertible has it's original trans and engine and still runs like a switch watch.😎
So many people destroy their turbos by racing around under boost and then shutting the engine off hot. Turbos spin REALLY FAST and they basically spin on a film of oil and the get HOT. IF YOU LET THE ENGINE IDEL FOR 2-3 MINUTES before you shut it off the turbos won’t fail. How do I know 2004 audi s4 250,000 on the original engine and turbos…..
I`m about to do this repair on my 2011 Tiguan at 116,000 miles. I will not be replacing the turbo, because its not necessary. Repair kits are available for the wastegate flapper....you can get them with or without the vacuum actuator. Here is a "how to" video....its not difficult at all. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kRHmjAD3JHc.html
