Product Description

This valve kit was developed for those who have tuned, or plan to tune, their 8S chassis Audi TTRS or 8V chassis Audi RS3 in excess of 450hp. Audi have seen fit to not change the design of the OEM dump valve from the previous RS3, so the same issues are carried over to the new 8V chassis, namely it was observed that cars over 450bhp were randomly getting errors from the stock solenoid dump valve not functioning. Whilst the stock valve will operate as designed, with the boost level necessary for 450bhp the stock valve couldn’t move the volume of air it needed to, so the ECU was seeing too great a positive boost in the MAP readings between gearchanges and assuming the stock valve wasn’t functioning correctly.

Forge looked closely at this issue, and noted that there would be no real fix for this as the size of the hole for the valve is too small in the stock elbow. They decided that they would re-design and produce their own elbow, allowing a much larger DV port, which in turn would allow fitment of a larger valve to take advantage of it. Forge also improved the internal flow of the elbow and removed restriction within the valve. The elbow design has been changed by Audi to accommodate a different throttle body, so their design has changed too.

We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner.
