Andrew-k Posted March 24, 2014 Share Posted March 24, 2014 Hi, I'm a new member and, at the end of January, took delivery of a 1.6 Focus Zetec automatic (petrol). Having got the car "run in" I find that, at speeds of 60-70 mph (less in windy weather) a loud and almost continuous penetrating whistle starts up and appears to be coming from behind the dashboard on the passenger side. The people at the dealership are completely at a loss as to what the cause might be (I'm taking the car back again in two days time!); can anyone suggest a possible solution to this? As it stands at present, taking the car on a long journey would be mental torture and there seems no end in sight to the problem. At present I am a very exasperated Ford-owner. Andrew-k.

BigD Posted March 24, 2014 Share Posted March 24, 2014 Does it go away if you hit the 'recirculate' button? I say that because the pollen filter housing is behind the dashboard on the passenger side. Other suspects would include some issue with the airbox, or a split hose (though, extremely unlikely on a brand new motor). Quote Link to comment Share on other sites More sharing options...
Andrew-k Posted March 24, 2014 Author Share Posted March 24, 2014 Thank you for the suggestion about the recirculate button, I will try that when I get the chance or tell the garage. Problem can be finding the time to go out and find a road where I can do 70! Quote Link to comment Share on other sites More sharing options...
artscot79 Posted March 24, 2014 Share Posted March 24, 2014 Are under the carpets wet ide say missing seam sealant if youre positive its behind the dash also adjust the heating knob see if that helps most mk2 have a wind whistle at speed but its just the design on the mk2.5 they used more insulation and thicker door seals Quote Link to comment Share on other sites More sharing options...
ChrisCooper Posted March 24, 2014 Share Posted March 24, 2014 Get similar on my Mk2.5, although it's not that loud and I can only hear it when the radio is off.No sign of any water getting in. Quote Link to comment Share on other sites More sharing options...
Andrew-k Posted March 26, 2014 Author Share Posted March 26, 2014 Many thanks for the comments/suggestions. Unfortunately hitting the Recirculate button didn't make any difference; the car is with the dealership at present. There is no way that it is any sort of normal wind whistle - nobody who has heard it has suggested that - and anyone who has heard it thinks it is coming from behind the dash on the passenger side, as in my original post. The front wheel-arch, door seals etc. have been checked and are OK. Any further suggestions, please? Andrew-k. Quote Link to comment Share on other sites More sharing options...
artscot79 Posted March 26, 2014 Share Posted March 26, 2014 to be honest accept it i believe its from outside and due to the aerodynamics since so many focis have the same issue live with it most of us do i cant say its that bad Quote Link to comment Share on other sites More sharing options...
Andrew-k Posted March 26, 2014 Author Share Posted March 26, 2014 Artscot 79, you haven't heard it! And it seems, moreover, as if something is loose because the noise reacts sometimes to vibrations in the road. Quote Link to comment Share on other sites More sharing options...
artscot79 Posted March 26, 2014 Share Posted March 26, 2014 Theres not much back there to be honest all i can think of is the pipework to the heater matrix wiring through the grommets or a faulty window seal without ripping the whole dash out its guess work you could take the glove box out and have a good look up behind the dash Quote Link to comment Share on other sites More sharing options...
Andrew-k Posted March 28, 2014 Author Share Posted March 28, 2014 Fingers crossed - the problem seems to have been solved. Eventually the dealership traced the noise to the door-mirror housing; it wasn't coming from behind the dash after all! There is nothing apparently wrong with the original housing but changing it stopped the noise and I had a brief run at speed last night and could detect no trace of it. Thanks again, anyway, for the suggestions and comments. Quote Link to comment Share on other sites More sharing options...
ChrisCooper Posted March 28, 2014 Share Posted March 28, 2014 What exactly did they change, the entire mirror? Quote Link to comment Share on other sites More sharing options...
Andrew-k Posted March 29, 2014 Author Share Posted March 29, 2014 I believe so, or at least the entire housing. Quote Link to comment Share on other sites More sharing options...
