Hi, my 09reg Panda Eco-active 1.1 leaks engine fumes into the cabin when running stationary at lights etc. It was previously much worse as the airbox offside mounting ferrule was loose in the moulding. I did manage to secure the airbox so that the engine vent tube is securely in place but still there is slight fume leakage. I believe the bulkhead is sealed during manufacture. Has anybody else had this problem?
