I have a 2007 Volkswagen California camper with 27,000 miles on the clock which went out of warranty on 22 July. An air conditioning hose has split which is going to cost around £700 to replace, because the whole front of the vehicle needs to be taken off for access along with the main radiator. Having looked at the design, the hose is held in place midway along its length by a metal ring on a 'stick'. The ring is in constant contact with the hose, hence it's worn through. The mechanic who looked at it at the dealership agreed that in another 27,000 miles the same thing will happen again. Volkswagen have offered to contribute 50 per cent of the cost - should I hold out for the full amount or settle?
