Getting a rattling noise from the rear of the car. It only happens in the wet and when the car has warmed up. Taking the fuse for the haldex out makes no difference, but I defiantly on happens in the wet. Any body had this issue and solved it? Everything I’ve read people suggest it’s the exhaust but all seem to have aftermarket exhausts, mines standard. Any advice would be great as I’d like to address the issue myself.
