E46 318i vaccuum pipes

Whilst under the bonnet of my e46 I noticed that these vacuum pipes are deteriorating not sure what they are for but can they be replaced?

I believe they are replaceable. A video on you tube from 50skid showed them behind the intake manifold. I don't have that on my 325i, but you should be able to just pull them off of there and put new vacuum line on.

^ Correct; they can definitely be replaced. Over time, those vacuum lines become brittle and start to crack, developing into one of the many sources for vacuum leaks.

Part number for that hose used is #11727545323: https://www.fcpeuro.com/products/bmw...rp-11747797175.

If you're looking for a substitute hose, inner diameter should be 3.5 mm and the outer diameter should be 7.5 mm (2 mm wall thickness).
