I have a 2011 1.6 Litre Seat Leon Diesel. The engine has been louder than usual and there is a vibrating when sitting in the car. The vibrating is worse when the clutch is depressed. Does anyone know what could cause this?
@johndoe177 this “The vibrating is worse when the clutch is depressed” could be a bad bearing or a worn pressure plate. Check your clutch a bit better and see if the noise sounds more like a grinding coming from the clutch area. Of course it could also be a vacuum leak as well as 100 other things that may cause your engine to develop a vibration. Consider having the OBD scanned to see if it throws a code.
