*arms open offering hugs*
If its intake hose your car would be jerking when releasing accelerator also made a loud dump valve noise which diesels should not make, but be prepared to fork over cash, like i said i went for a £20 job and ended up spending £1250 lol, but fingers crossed for you mate hope its a minor boost leak not a major one like mine
Yours is 2.0Tfsi so is different engine to mine but the hiss isnt supposed to be there on the TDI engines as mine has gone now, i think the 2.0tfsi has a standard dump valve/ resirculating valve so thats what it must be on yours
Alsong as no smoke was leaking out of you boost hoses im sure your car is fine mate, plus if theres no jerking whilst driving then there isnt any boost leaks as thats a main diagnosis of a boost leak, plus petrol turbo cars sounds better than diesels and i can say that as im a TDI owner,
i guess it is lol i have spent a few quid on it :-/ lol wont be selling it now so it will stick with me forever
