+1, forge do make a diesel dump valve, has no real use other than to make a sound. And it costs £300 quid. Hardly worth it!
...not exactly. Iirc it takes a small amount of compressed air from the intercooler pipes stores it and releases it when the throttle is released from full throttle position much like the "speaker" dump valves which do th same but have a tweeter mounted that makes the noise

Fair does. Just wanted that bit of noise that comes from a dump valve. I'm not bothered about speed or performance, I have a 1.2 tdi so that's enough for me. So why can't you put a dump valve on a tdi?
as they don't work like a petrol engine a diesel has to have a pump to create a vacuum and a dump valve needs a vacuum for it to release.
you would need a kit like this

Lol, seriously man, don't even think of fitting a dump valve on a 1.2tdi even if it was possible, that's just wrong 
There's another thread on here somewhere with more info, someone asked the exact same question but they had a tdi with poke.

It was me. I researched a bit and it looked expensive and would make me look like an idiot at the end of the day so never bothered
Iv heard them on youtybe and thry sound odd. Not my cup of tea. Don't cheapen your motor with crap. Use the money and get a remap

My advice, open cone it, wind the windows down and enjoy the turbo flutter
Agree I love my jr cone filter the sucking sound is nice and the flutter sounds really good lol best thing I have done to my Cupra tdi
Open cone often leads to heat soak - stick with the standard filter as its been proven time and time again that this is all a diesel requires unless you're running daft power.
The item that you'd fit to the diesel engine is called a "blow off valve" not a dump valve, doesnt matter if its fitted to a diesel or petrol it works in the same manner in that it "dumps" excess boost pressure to atmosphere which apparently prevents the turbo over spinning during gear change, its yet to be utilised by any major names which makes me doubt its credibility but its a nice thought and some people enjoy the noise.
