Can anyone help me identify a knocking noise that you can actually feel for just a few moments through the throttle pedal. It only really happens when you begin driving the car from a cold start, the knocking feel/noise appears to come from some sort of grinding that is transmitted through the pedal when you do a full left or right hand turn, immediately after starting and pulling away etc. After driving the car this noise doesn't appear to come back again until you cold start the car again, it occasionally happens again mid drive. Has anyone come across this before or can give me some sort of idea what it could be. I would be really greatful if you guys with more knowledge could give me some feedback. I have a 2009 Focus 1.8 tdci titanium model. Any more info, just ask. Thanks.

This was my thought as well. Thought I'd curbed an alloy once when I was pulling out of a parking space, it was so loud!

Thanks for the feedback guys. Is there any way of stopping this noise. Is it serious.

Hi Kevin, its probably your Dual mass flywheel that had split/seperated? I had a similar problem: When i pressed down the clutch pedal (standing still whit the car, engine at idle) and hold it there i felt that the clutch pedal was pulsating / knocking. Luckily my insurance paid for the new flywheel and the work.
Good Luck!

dmf is a big leap could be the clutch or slave cylinder have a garage look at it first
