Hey! I’d be more than happy to help provide a bit more information about the DV+ for you. The main design philosophy behind the DV+ range is to achieve better boost holding, solving boost leaks and improving throttle response. We achieve this by replacing the weaker plastic components with reinforced metal components. The increased amount of throttle response is achieved through our pilot actuated system also. In some cases as well where an above factory amount of boost is achieved, the weaker diaphragm or piston styled diverter valves will either tear or leak boost - by replacing the weaker components were able to ensure boost is held. If you are concerned that your valve is not working correctly, or is not giving you the benefits you believe it should, please contact our engineers at support@gfb.com.au. We will be happy to look over any dyno graphs or other data that you may have.

No, the DV+ is not a blow off valve, it recirculates the vented air the same way the factory valve does. It is designed for performance and longevity, not sound. However, for a blow off sound you can use the VTA T9458, which is basically an atmosphere-venting version of the DV+.

What are the benefits that you feel at the acceleration? I buyed mine and its on the way, maybe I will install mine tomorrow.

Virtual Car Wash jeez use proper English, you bought no buyed

Did you fix it?

Hi Hafizi, The T9358 is not an atmospheric venting valve. It is fully re-circulating and so will have the same sound as the original valve. It is designed to be a more high performance oriented replacement for the factory valve

Unfortunately the DV+ won't fit a 2008 C300, as that car doesn't have a turbo.

Hi Lucas, It is not normal for the DV+ to trigger any warning lights. Depending on the specific vehicle, it may need to be set up slightly differently. Could you please email us at support@gfb.com.au with some more details about the engine code and what conditions this issue occurs? We do have lifetime warranty on all our parts so we'll be happy to help solve this issue for you

Hello, If you need some specific technical help please contact us at support@gfb.com.au If you send some video that shows the issue you're having that would help us get to the bottom of what could be going on

Good luck! I'm sure you won't have any issues, but if you do need help or have any questions feel free to email us at support@gfb.com.au

Unfortunately this product doesn't fit your car, the T9358 is only suitable for facelift models 2016-2018.

The same diverter valve, T9358, will fit the A45 - provided your car has a factory fitted diverter valve in the first place. The first generation A45 from 2014-216 actually had a blanking plate where the diverter valve would usually fit on the turbo. At some point in 2016, Mercedes replaced the blanking plate with a factory diverter valve, and only these cars can be fitted with a DV+. So it would be worth having a look at your car to confirm if it's there or not before purchasing a DV+.

@@gfbvideos Thank you for your reply. T9358 will be fit my car.
