We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner This valve kit was developed for those who have tuned, or plan to tune, their Audi TTRS or Audi RS3 in excess of 450hp, as it was observed that cars over 450bhp were randomly getting errors from the stock solenoid 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 amount or 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.
