Started intermittent but now it's every journey. Start the car and all is well, get to work for example and there's the knocking noise. I can even feel the vibration slightly through the brake pedal but the revs are fine and calm. Drop the window and all sounds smooth and well.

Turn engine off and back on again sometimes clears it but sometimes it's still there.

Any thoughts?

You will need to listen carefully and have volume up to make it out on the quick video I took with my iPhone.

Didn't get any replies to this initially but a girl at work asked her husband who is a mechanic and works on all his own cars. Based on how I described this issue and a brief audio recording, his initial thoughts are that it could be thrust bearing on clutch or output shaft on gearbox.

 

Any thoughts?

As the video doesn't work I wouldn't be able to help in anyway, except for that if it is the clutch bearing pressing the clutch to the floor would stop it from doing it, of there are no rev fluctuations then it could be all sorts of things loose engine mount, maybe an old auxiliary belt they can make some funky noises on these because they are stretchy, could you upload the video to youtube or pm it? Edit. The zetec se engine is a beauty for making funny noises from all directions.haha Sent from my GT-N5110 using Ford OC mobile app

To be honest the audio recording I've got on my iPhone is far better so I will try to upload that at some point. This knocking also occurs when stationary at lights and in gear so not just in neutral. Also, if I get out and open the bonnet and close it again, the noise stops! It is so annoying and is now happening all the time. Of course, it will conveniently not happen when Ford have it in just like it didn't happen in December but then did it on the drive home!

Check all of the things that can move then, make sure the air box is attached at the back, wiggle the coolant bottle, push the power steering resovoir down because that can pop up, make sure the battery is bolted down, check the radiator look at the heat shields all over the bulkhead as they have rubbish screws that rust and break off.

Hi I also have the same noise on my car, its been back to Ford twice but they cant seem to find anything wrong with it. the knocking starts when the first block comes on the temperature gauge and the goes off when its up to temperature. It only started when it was getting cold in November and I think its getting worst.

It's all aluminium there is no way for the noise not to be present, it should go away after a few minutes, once the aluminium has expanded and the looseness has subsided, regular long drives in my experience stop the noise being an issue, it seems also a factor that the thin oil used also returns to the sump very quickly after shutdown meaning a dry ish top end which is where the main body of movement occurs in valves and cams.
