Mondeo TDCI Ghia x Noise - markr
I have a noise (a bit like a diff whine)which is most prevalent when travelling between 40 -50 mph on my 52 plate TDCI Ghia X estate (23000 miles on clock)

I can't work out whether its coming from front or back.

The noise doesn't change when going round corners or when I turn the wheel slightly in either direction

Anyone got any ideas - my local Ford garage has taken a look but couldnt find anything and suggested it could be tyre noise (I dont think so)

My 2001 1.8 petrol Mondeo has always had a transmission whine at 50 mph, but its not bad enough bother about.
I think all the cars I've owned with 5 speed boxes have had some sort of whine at about this speed.

Does the noise vary in pitch according to road speed/engine revs?
It would sound like a road-contact-tyres issue if the former, and an engine issue if the latter.
I get a small but noticeable amount of turbo whine with mine which I'd rather listen to than clackety diesel noise!
Just some thoughts in terms of narrowing down the cause.

Could be wind noise, the rubber strip at the top of the windscreen used to be a problem on the mk3 Mondeo, supposedly fixed on the later models.

Hi I have a 2002 Ghia X TDCi 5 door hatch, I previously noticed a slight noise that I thought was some kind of whine at motorway speeds, I pinned it down to being from the sunroof, it stops when I shut the sunroof blind.

Regards.

I had a similar noise on my new Mondeo - Ford garage traced it to feathering on a front tyre - swapped back to front and problem solved.

Mondeos are heavy on front tyre wear. Make sure that the wheels are correctly aligned (take a trip to Micheldivers in Andover!). Since I have kept an eye on this, tyre wear is substantially reduced as is feathering,and odd noises!
