This valve kit is an evolution of the FMARSDV dump valve we market for the 8P chassis RS3. It was developed for those who have tuned, or plan to tune, their 8S chassis Audi TTRS or 8V/8Y 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.

We 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. We decided that we would re-design and produce our own elbow, allowing a much larger DV port, which in turn would allow fitment of a larger valve to take advantage of it. We 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 our design has changed too.

With the engine management on this engine being MAP based rather than MAF based, which is unlike many other Audi engines, we have also incorporated the option into the kit, of being able to run as a recirculation valve or with an atmospheric discharge/blow off. 

An uprated white spring is included with this kit to cater for those with an upgraded ECU

A service kit for this valve can be found here. We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

Does its job very well
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
Been using Metamucil for years. Because it is a quality product that dissolves well in water, tastes fine, and a very easy way to stay regular. Considering what it does for my system, it is a cost efficient way to get more fiber in my diet with no side effects.

Excellent product!
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
I held on to this product for months before trying it. Wow! Not sure what took me so long, but I am so impressed. First of all, it is easy to drink - just do it quickly. The taste is surprisingly refreshing. Even more important, it works. If you have IBS or other digestive issues, you may be pleasantly surprised at how it helps these issues. I just regret I didn’t start using it years ago. I take at least two drinks a day, sometimes only one.

Works well and easy to add to a daily routine
Size: 2.3 Pound (Pack of 1), Style: Sugar Free 180 count
This Metamucil works well overall. It mixes pretty easily, the orange flavor is decent, and it’s been a simple way to add more fiber into my daily routine. I like that it’s sugar-free and uses psyllium husk, so it feels like a practical option for digestive health without adding extra sugar. The texture is what you’d expect from a fiber powder, so you do need to drink it fairly quickly after mixing. Overall, it does what I bought it for. Taking off one star only because it’s still a fiber drink, so the taste and texture may not be for everyone, but it’s a solid product.

My doctor encouraged my use of this product to lower my cholesterol. Okay, months later, no difference with cholesterol, but the produce makes elimination very very clean and I like that, so I still use this product.
