As I'm still awaiting my Haynes manual from eBay perhaps someone can help me identify this hose on my 2005 A3 2.0l TDI? It's seen better days and I think it needs replacing. I don't think it's split, but some of the outter jacket of the hose appears to be missing. The damaged section is just about visable in the picture, it's the area that is a darker colour. What do you all think?
