Hoses to and from the engine cooler fitted to the 220 and 250kw AU's are prone to rubbing against the crossmember and wearing through. I recently sourced a more flexible replacement as this happened to me and have posted the quotes for people to use if they like. Quite well priced at the time and the supplier is able to mail if that's what people want. Quotes for both black kevlar/nomex braided (black is the more flexible option) and steel braided silver here:
