I've had a search around on here but can't find anything that fully relates to my problem. The split doors on our Cooper D Clubman, 2009, will not open. They were fine earlier today, but when my wife opened the right hand door, instead of the sort of quiet hiss that usually comes from the hydraulic arm, she said it made a noise more akin to a cow mooing. She closed the doors again and after shopping tried to open the door with the keyfob remote. It just makes a grating/whirring sound and the doors remain locked. The same happens when you try to open the door manually with the handle. Any ideas out there? I'm guessing the hydraulic arm is knackered but I'm open to any other suggestions. Just paid an arm and a leg for a new clutch so don't really want to take it to a garage again any time soon.
