My VW GTI has been a little slow lately time to make it go fast again. I'm upgrading from the old diverter valve to a new upgraded piston diveter valve from ECS Tuning, along with burning rubber and real world dyno testing
I'm barely learning about my gti/cars so i was wondering if it would affect my car at al or if I can even install a blow off valve on my automatic transmission gti?
+Alex Santiago Yes you can install a BOV on auto transmission though it wont vent as frequent as manual because it happens when you lift off accelerator ex shifting. A diverter valve holds boost pressure when accelerating then lifting foot off the gas recirculates air back into engine helping spool turbo faster. A blow off does the same thing but will vent the air outside. I plan on switching to the CTS BOV which comes with an electrical plug to prevent a CEL
@@FastSloW-qt8xf Yup, in the manual or dsg transmission you will notice a decrease in throttle response when shifting gears when venting to atmosphere instead of holding some pressure.
I had the same issue with the same code in my MK6. Replaced my diverter valve with the upgraded one from ECS. it was good for a couple of days but yesterday the check engine light came on with the same code
225 miles at 3/4 tank!?! WTF was wrong with that car :( I hope the DV leak stabilized the fuel trims. If I get less than 380 a tank I get really worried.
Did it sound like it was leaking boost? My mk7 threw the same code at around 127mph mid pull & afterwards it would only build 25psi with a pretty audible boost leak. I’m hoping a newer revision dv will do the trick. 😅
If you can hit 25psi it's definitely not the diverter valve. What boost pressure do you normally hit? My mk5 ko3 turbo at 100% duty cycle maxes out at 21psi due to the internal waste gate. If you were getting higher boost check your intercooler connections.
@@OfficialExcide dang mk7's don't mess around im on a Eurodyne tune. I think if it were the diverter valve you would have more than a 3psi drop. But I can't say for certain whats going on.
Hey changed my diverter valve yesterday and it turns out it is the same as the one you installed so pretty much it was just a replacement. I drove the car for two hours and the power came back. But then the light turn on again ! And power lacking came back. If it wasn't the diverter valve then why did the power returned ? And what other possibility can cause this light. It is still the same code. Makes me want to trade it for a lexus gs350 just for reliability but I really like this car as far as looks power and gas efficiency.
Savage GTI thanks. I found a aftermarket turbo exact one but not made by audi. Kind of like the diverter valve. 850 dollars. The only thing that bothers me is this car only has 73k miles. Smh. I hope I fix this issue
ayokarlos I replaced the diverter valve. And turned the light off. All power came back. Then light came on and the the power left. Then two days later light went off on its own. And it's been 4 days and the power is back like when I first bought it. I believe the computer registered the new diverter valve.
@@SavageGTI thank you just ordered new seals for the inter cooler pipe and I will be sure to get a new diverter valve too. The sound is exactly like that so it is definitely a leak.
It's called Torque Pro. You need a Bluetooth OBDII adapter to use it. Good for a cheap engine scan. For more advanced things I'd just recommend getting VCDS so you can also check every aspect of the car and recode additional features.
I had an oil leak from the diverter valve plug area. I removed and check diaphram and its not ripped . I replaced with new revision D and its still leaking a bit oil from the plug. Any ideas?
I recently encountered that as well I had another boost leak from the turbo outlet pipe. My guess is it's coming from the turbo outlet pipe you can follow it from the intercooler up to the turbo and look for oil leakage where each pipe connects. The oil here is all blow by I wouldn't worry about too much unless it'smaking a mess or your loosing boost pressure.
Did you have to reprogram your car so it can handle that new Diverter Valve? I heard it can cause some problems if you Rev it too much and cause combustion in your engine... how has it held up?
No it works fine with a stock tune or a tune file. It has nothing to do with the engine. Any combustion should be in the engine lol. It's function releases the boost pressure to the atmosphere apon lifting the throttle. The stock diverter valve recycles some of the air and puts it back through the intake. The BOV I have has been great for years and still works great. It came with a dummy electric plug so the circuit isn't broken and doesn't throw a code. It is now actuated on vacuum pressure as aposed to the stock electric signal.
@@SavageGTI thanks! I just placed an order for one! The one I bought comes with different springs so I can control the psi level that goes through! Thanks for sharing and the explanation!
To answer how it held up. It was a rare case for me the piston part separated from the body and I upgraded to a Blow off valve rather than a diverter valve
@@SavageGTI oh I see! I coincidentally bought one without pistons... it was the only one that would ship to me on time lol... I ordered this one: www.ecstuning.com/b-apr-parts/r1-diverter-valve-priced-each/dv100001/
Savage GTI ok. I have a 2013 Audi A6 2.0 with 73000 miles and check engine light came on. took it to the dealer and they told me to look up p0299 code. And I already ordered this part. funny thing is that the power still there. so I assumed the piece just started to wear.
Yeah if your diverter valve has a crack or small hole pressure will leak out. Car will still get boost but not full potential. would be weird if you have full boost because the code reads as a boost leak
Savage GTI it turned on Thursday. then say came off on its own and I got full power and then turned on again today on the way to work. ordered this part. hope it fixes the problem. the power is there. this started happening after I did a software recall service for the power coolant. wonder if doing a software update since it is the computer can cause the sensor for the diverter valve to fail
Thanks, yeah it seems like the U.S spec German cars get a lot of features removed and less options compared to Euro spec models. In the US you can buy a gti with regular plaid seats or heated leather. I think the new mk7s you can get recaro seats as an option.
Torque Pro (OBD 2 & car) which is $4.95 there is also Torque Lite which has less features but free. the dongle I have is "iKKEGOL® Bluetooth Mini ODB2" you can get it on amazon for $12.89 but any bluetooth OBD2 device will work
No this will not fit the TDI, I'd also check your intercooler pipes for any boost leaks. Look where the pipes connect together, if theres any dirt or oil build up air is escaping and lowering boost.
No you can have one or the other the diverter valve recirculates some of the boost back into the engine while a BOV vents to the air with a cool noise. I am currently running a BOV on my car now and this is the video on that ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-i3jDIAuXaUY.html
+sean poquette In this video the tires are what the dealer gave me, recently I needed new tires to get me through snow without buying snow tires. At this point I'm pretty sure it's just a stock tune the torque app isn't the best for HP. And I put on intake and exhaust for performance so far.
I used Torque Pro there's also Torque Lite app for free but you also need a Bluetooth OBD2 scanner. I don't think it works on ios. you can do basic engine code scans but a VCDS cable is far superior allowing you to scan all modules like ABS ect. and do vag com mods.
@@adlp12 yup this would work. www.amazon.com/OBD2-OBDII-Bluetooth-Diagnostic-Scanner/dp/B01HXGX8V6/ref=sr_1_7?ie=UTF8&qid=1544752163&sr=8-7&keywords=bluetooth%2Bobd2&th=1
In this video I used "Torque" it's good for basic engine scans and works for all OBDII vehicles, you will need to buy a Bluetooth OBDII Scanner separate. VCDS is a much better tool for diagnostics and cool custom coding on cars like VW and Audi.
@@ammaar7741 I wouldn't bother with them they are just a gimmick and still use the factory diverter valve, I made a video about the CTS BOV and that is what I am currently running. It's a solid build construction with an o-ring. The BOV is mechanically activated and with my Eurodyne stage 1 tune I can hold 18-21psi no problem and with good throttle response.
My new one also broke, a rare occurrence for the revision D. I've since replaced that with the CTS BOV. Talk about fun and pshhht sound every time you lift off throttle, also works in nutral because its vacuum actuated
The oil is all "blow by" it comes from oil going past the pistons into the crank case and through the PCV (positive crank case ventilation) which routes oil vapors through the intake to be burned off. Thus oil going through intercooler lines and out BOV. A Catch can should eliminate this problem.
bummer sounds like you've been at this code a while, I would make sure air filter is clean too. look for any hoses or spots where there could be an intake leak. I haven't had that code pop up for me so idk.
Most likely diverter valve especially if the car feels slower and any passengers don't feel that stomach feeling. Also check the spots where the intercooler pipes connect if you see oil and dirt build up there is a small leak there. This was a problem with me when I actually tuned stage 1 Eurodyne the car would stall after a pull and wouldn't idle.
@@SavageGTI Thanks my dude, yes the whole stomach feeling is gone and it feels like the car got like 150hp. i dont hear any weird noises or whatsoever though.
@@jorrrdy You don't necessarily need to hear something, if the engine runs fine but is down on power it's within the turbo system, and if you have a low boost code on an early model mk5, diverter valve is most likely the issue
@@SavageGTI Dumpvalve was torn. Replaced but didnt solve the problem. Local garage cant find anything. He is blaming the tune on my car. Going to the tuner tommorow to undo my chiptune and my pops and bangs. see if that works, probaly not. but oh well...
+greezmkey84 payen it doesn't matter what fuel or what power you throw at the car. If there is a leak in the turbo system you will only make what goes through the throttle body
