In Topic: 2011 Smax Occasional Knocking Noise - Video Inside!

hi, did you get an update from this. Mine seems to have the same problem. Drove home with my new second hand s-max (2.0 tdci titanium automatic gear, 2010) and on arrival (party killer), at idle, it had this faint knocking noise. Didn't have it at any other time during the 140km drive. Didn't have it when I drove it today. Like you mentionned you hear it mainly from the inside. Not sure if it followed the revs with us. It was gone on its own some time after we turned of the A/C and/or the motor ventilator stopped, so not sure which of the two would have contributed to it stopping.



No we still haven't identified it and it still occasionally happens.  The local Ford dealer has supposedly had a good look around but as it hasn't happened in their presence they can't diagnose it.  It still only occurs very occasionally.  


The last time it happened I lifted the bonnet to see if I could better identify the area and whilst doing so I noticed the radiator cooling fan, which was running, turned off.  I went back inside the car and the knocking had stopped.  I did tell the garage that I thought the two could be connected but again they were unable to find anything.


Please do let me know if you find it.


Good luck!

Take the car to Ford - this will be covered under warranty.


I hope so, my concern is the problem won't occur the day we take it to the dealer and therefore can't be diagonsed and fixed and may then manifest into a bigger problem once the warranty has expired.


Maybe a wheel bearing on its way out if its only happening when the cars moving?


No, the video was taken when the car was stationary, so definitely not wheel bearings.  Thanks for the input though :)

Welcome to the club. Where abouts is the knocking noise coming from?


I haven't been able to locate it, but I am guessing low down and to the back of the engine bay, hence why it seems to be clearest from the front foot wells.  it is not audible from the engine bay above the noise of the tick over.  Next time it happens I will have a much more thorough search for it!


does this happen only if you have fans on or air con on?


Also is the fusebox fully secured in place?


Not sure, but will test a run with both.  I'll also check the fusebox.  


Thanks both for the input  :)
