1.2 TSI Forge Dump Valve hose Issue

[JayW]

I had this dump valve since Wednesday and it's working fine, however I noticed an issue with the silicone hose "collapsing in on itself" much more than it should I believe. Infact it squashes down so much during vacuum it creates a weird sound which I can only describe as a "THRUMP" sound. This only occurs during idle and reverse or where a large vacuum is suddenly created causing the silicone hose to collapse and squash down on itself. The blow off valve itself works perfectly fine and does the correct job and makes a very nice sound!

I have contacted FORGE and they quickly replied asking me to show them a video of what I mean in which I recorded and showed them this video:

They got back to me within the hour and a new hose was sent out via next day delivery! Can't fault their customer service, absolute top notch! Hopefully this will fix the problem, because the hose I have right now is much much too flexible and has no rigidity in it at all. From what the technician told me, the hose should be reinforced and rigid to stop the hose from collapsing in like that.


Has anyone else had a similar issue with their dump valves?

Hi jay had no problem on mine that's strange, I have the receipt I will post it to you.

Yeah, it might just be a problem thats occured whilst i was driving it. Didn't realise till the day after when i picked up the noise then saw the hose squashing in on itself when it should be rigid enough to stop that.

Its no probs though, if worse comes to worse i can just get an Alu one made up with silicone joiners on each end for flex.

Thanks for finding the receipt mate
