Ford Ford Ecoboost whoosh noise

Beerbaron · 10 Jul 2017 at 07:32

I recently bought a 3 year old Focus 1.0lt Ecoboost and notice that there is a slight whoosh noise when i change gear (foot down on clutch) in anything above 3rd gear. I can only hear this with the window open. I know these cars have a very small turbo but is this noise normal or should i take it back to Ford to look at?

Thanks.

Sounds like the diverter valve doing its job to me, not driven a 1.0T ecoboost, but pretty much every small turbo I've driven has sounded as you describe.

Yep, completely normal. Mine does the same, you'll only hear it with the window down. 'tis quite a nice sound

As another Focus 1.0 ecoboost owner, can confirm that it is completely normal

Great, thanks chaps

If it's quite loud check the hoses are on tight. Hoses coming off is a thing on these engines. Quite a few people had it on the Fiesta STs due to the clips being to loose from the factory :/

My initial Google suggested the hoses.

I'm not sure if it's the same with the Focus, but the Fiesta has slightly higher boost pressure in 3rd gear upwards. So if you put your foot down at low revs in 3rd and release around 2000-2500rpm, you get quite a loud chirp.

No chirp just a slight whoosh.

Anyone with a 1lt ecoboost, how many miles do you get out of a tank? I get about 380 miles which is mostly motorway and A roads. My previous 11 year old 1.4lt Astra SXi did 440 although had a slightly bigger tank.

I have the Ecoboost Fiesta and get around the same beerbaron and thats around average for the 36k I've done in it.

Armageus · 11 Jul 2017 at 08:11

Haven't paid attention to the range, but get an indicated 44.5mpg over the 10k miles or so that I've had it.

Not a whole lot more than my tuned Fiesta ST got lol

I get around 400 miles per week for 35/36 litres of fuel. So around. 50mpg typically. It's mostly motorway driving outside of peak times.

My mpg counter hasn't moved since i bought the car so no idea what its doing. There is an instant fuel gauge but don't know what that refers to.

As everyone else has said, its the diverter valve doing its job, I even notice it on my work 2.2TDCI Transit Custom

The Focus is also 200kg fatter than a Fiesta ST, what do you expect

Beerbaron · 13 Jul 2017 at 07:10

Just checked and the average mpg hasn't changed from 41.7 since i bought it end of May.

Do you know when it was last reset? Obviously if it hasn't been reset since it rolled off the showroom then your usage in the space of a month or two might not make much difference.

Or its knackered.

Beerbaron · 13 Jul 2017 at 19:26

No idea when it was reset. I've probably done 1500 miles and the car has done 17,000 miles.

If mine didn't spend the majority of it's life doing a 4.5 mile commute, it would easily do 48mpg or thereabouts (as it did when I tried on a long run)

Fortunately 44.5mpg is considerably more than the ~31mpg that my 2.0TFSI A3 managed consistently on the same commute

I'm getting about 55 scooting around fife the now, usually closer to 45 nipping towards Glasgow everyday
