Hard to tell from the images, but has the hose wall actually split or is it just the inner lining all torn up? 3rd image at 4:30 o'clock ish, is that a split in the hose? Looks to me like its been taken on and off a few times over a sharp edge and torn the lining away.
According to receipts I got with our car it had two full sets of hoses done by VW in 90k odd miles. As I recall they charged £130 for the set.
