Being a careful type at the end of Feb this year I had my cam belt and tensioners replaced on my scenic 1.9 dci having covered just over 50k (£300 +). Last week my car suddenly stopped. The drive belt (fan belt) had snapped and forced its way behind the bottom pully and lodged into the bottom cam belt pully. The result is a hefty bill for bent valves etc. Not pleased with the garage who did the repair having read in the Haynes repair manual that if a drive belt is removed for any reason it should be replaced, It wasn't and we're in dispute. Does anyone have any further information which refers to a requirement to change the drive belt (fan belt) during a cam belt repair.
