Specific Product Information
Relevant tech information
- Capable of handling upwards of 50psi.
- Direct-fit replacement with GFB’s TMS benefits.
- Unrivalled longevity.
Features of VTA:
- Utilises pilot-actuated operation, allowing for increased throttle response and better drivability.
- Replaces weak plastic components with metal components which solve boost leaks and improve boost holding.
- VTA progressively opens in response to boost pressure – only opening as much as is required.
- Features an inbuilt solenoid, absolving the need to disassemble your OE diverter valve solenoid.
Use cases:
- Applicable for VAG vehicles that utilise an electronically controlled Continental diverter valve.
Self-troubleshooting steps:
- How do I diagnose my valve?
o With the valve uninstalled from your vehicle, inspect the piston to make sure that either the silicon face or VITON seal is undamaged and that there is a small 2mm hole in the centre of the piston. It’s also normal to see some vertical rub marks on the piston. Next, inspect the body and piston together, ensure that the body is clean, and that the piston is able to travel in the bore without being obstructed. Afterwards, inspect the plunger to see if there are any signs of damage or wear. There will be tell-tale signs of damage if the plunger is hitting something that it shouldn’t be hitting.
Next, we would then recommend double checking the condition of the connector and of the providing wiring loom. Check to see if everything has been connected correctly and that the loom itself has not suffered any physical damage.
- How do I know that my VTA is working as intended?
o Uninstall the VTA from your vehicle and lay the body of the VTA on its back and press against the piston. You should be able to press against the piston without getting stuck. If the piston is seemingly getting stuck, please send us a video of this to [email protected]
- I’m finding that I’m losing boost whilst on throttle! Help!
o If you’re experiencing this, we highly recommend double checking that you’ve used our GFB provided plunger spring and not the plunger spring that was included with your OEM solenoid. Using this spring would result in the VTA to prematurely vent whilst accelerating.
FAQ:
- What is the difference between the VTA and DV+?
o It worth noting that only key difference between these two valves is that the VTA will make a “whooshing” sound after coming off throttle, where as the DV+ will not. They both have the same performance related benefits as each other being improved throttle response, better boost holding and solving boost leaks.
- What’s the difference between this VTA and our other VTA’s?
o Unlike our other VTA’s that we currently have available, our integrated solenoid VTA’s absolve the need to reutilise your OEM solenoid. This means that you will no longer need to fumble around and disassemble your OEM solenoid to fit the VTA. The VTA will simply now replace the OEM hardware.
- What is the actual size difference between this VTA and one of your other VTA’s with the inbuilt solenoid?
o Compared to our other VTA’s that reutilise the OEM diverter valve solenoid, the integrated solenoid VTA’s are significantly smaller. This means that you will be able to have both an aftermarket turbo inlet pipe and our VTA without encountering any fitment issues.
- Do I need to have the OEM diverter valve solenoid still plugged in?
o No! Unlike our other VTA range, you will not need to reuse your OEM diverter valve solenoid. You will simply need to use the provided loom to connect to the VTA.
Next steps:
If you are still having trouble, then the next steps are to contact our Tech Support team. Videos, photos and a clear description of the symptoms you are experiencing would give us a better understanding of what is going on and how to resolve this issue as quickly as possible. Remember, we can’t see your car or product, so our diagnosis is only as good as the information that you provide us.
