yeah, the braiding on mine is in a real state, i stretched it out and clamped it down with a jubilee clip a couple of years ago but thats rusted and broken away, i have left it alone since as its not really a problem.Is the section actually blown ? Or is the outer mesh just loose ?
Had this on my Astra once years ago, was loose for years but no consequence as wasn't leaking.
Just a thought
