Hi guys.
Little problem with my Leon cupra. I have a hiss / whine when turbo kicks in
I've pressuresed the piping up to 30psi and it all holds for 5 mins.
So no leaks but still getting the code and noise when I boot it
Any help appreciated thanks

Could it be the diverter valve on its last legs?

I tryed another second hand one still same. How do you check how much psi the dv holds

To be honest I'm not sure I'll have a search for you. Having searched the code it suggests a leak but as you've done the test and that is ok then it's obviously something else.Will get back to you if I find a possible solution mate.
