Hiya folks, I’m wondering if you might be able to help? We are trying to find out what this pipe is/does on my guys Audi A4 2.5 tdi 2002 Quattro Sport (this is an Internet pic but it’s the same). Really struggling to find parts catalogues or numbers for this car. If someone knows, please reply (he has no hair left and I’ve square eyes from internet searches!) Ta muchly 😊
