    Hello experts ;)

    This hose has split in my s3 and it cant be bought individually from AUDI. It comes with two other hoses and clips that I don't need if I buy directly from them and costs over €100.

    I have it removed and was wondering can I use 4mm ID silicone hosing similar to that used for the n249 bypass?

    Also what does this hose do?

    Thanks for looking and hopefully somebody can help :)

    That goes to the n75 valve, which controls wastegate opening and subsequently boost. Just get silicon the same internal diameter, it should flex enough to fit nicely

    I'm not sure of diameter. Youl be needing proper 3 ply silicone too at least, not vac hose. It gets hot round there.

    looks bigger than 4mm to me, but as Karl sad, its pretty flexible so should be able to get it to shape :)

    Glad to be of assistance! I fitted them a few days ago, they're a perfect fit so only took around 30 mins

    I got the same ones in black. Seem pretty well made. The bracket needs slight bending to get the DV one in but that's to be expected as it's a little larger.

    You need 6mm silicon... 4mm is too small
