Where to get oil feed restrictor bolt (banjo)

[Armands]

Hello

Recently I changed turbo, on my a3 PD170, as the old one was gone, and when i put it all together, oil feed line started to leak on this turbo. it is leaking from the connection with feed line and turbo.

So i want to change this bolt which is connecting oil line and turbo with new one, but I cant find it anywhere on internet (eBay, dark side etc).

Not sure, what is the correct name of this bolt, but i found out that it is Turbo oil feed restrictor banjo bolt.

I found out that other turbos they using normal thread bolts, but on this PD170 it is bolt with revers thread.

Please help me to find where to buy one of them or atleast what is SKU number or should i go to dealer and ask them for it?

Thank you for help
