Sorry about the crappy pictures!

Thanks

It's commonly known as the S pipe, & is notorious for splitting. It's ok to run it like that as it's not an engine destroying problem, but the engine will run better if you replace it.

These have now been modded and are a braid reinforced design. (Well the last one i bought from Audi was).

Coolio, do you know how much it cost? I can get a silicone replacement for £20.

I just replaced mine. Was a tenner on eBay but was the same rubber hose it replaced

Around £27 from Audi but I get trade

I replaced mine with the ebay ones. Should last long enough to not be my problem if they split again if you know what i mean
