Howdy folks,

1st post – apologies for the long post.

I have a 2010 Focus Style 1.6tdci (approx. 16months now) basic model

I clock up a fair bit of mileage between commuting and driving up and down the country.

But this is mainly motorway driving not stop-go-stop all the time,

I've read through plenty of forums and have come across a lot of cases that this car is known to be loud on the road.

So I was aware of the road noise (the road noise from the tyres etc.)

Anyway, my question is related to engine noise.

Over the past two weeks I've noticed the engine becoming louder/nosier,

but it only gets noisy when I go above 60-70kph(40-45mph)

and as I accelerate the noise becomes louder 100-120kph (2000-2500rpm)

So when I’m on a dual-carriageway/motorway this noise is very loud and need to have the radio loud to somewhat dampen the noise.

Now it is hard to describe the noise, hope I can explain it correctly….

It’s not a buzzing or rattling noise but more like a humming noise that gets louder as I accelerate

Once or twice last week it did shudder as I was slowing down coming off a motorway.

I’m wondering could the noise be down to blocked filters or something or exhaust

I’ve read suggestions on other forums that say it could be exhaust related or belt rubbing??

I should also note that it received its 2nd serviced only 2months ago where oil/air filters etc. were all changed.

So, just wondering would anyone have any suggestions or any experience as to what may be the cause.

Cheers

Have you tried Cleaning out the EGR Valve mate,

could be carbon buil up in the valve, restricting flow
