Hi
Can anybody please help me. I have a 2008 Passat tdi, it's a CBAB engine the car drives fine when it's cold but as soon as the engine warms up I can hear a booming noise when I'm sat inside the car. I've jacked up the car and removed the undertray thinking maybe it's the dual mass flywheel on its way out but I can't hear anything, I know it not much information to go off, I just hoping somebody has come across this before, there's no change when I press the clutch down it just seems to be as soon as the engine warms up. Thanks
