I purchased a Ford Fiesta 1.0 Ecoboost 95 titanium 70 plate from my local Ford dealer a couple of months ago and everything has been fine except for an annoying chirp tick noise at idle once the engine has warmed up. I took the car back to the dealer for a check and the service department said normal operational noise for that car. I wasn’t quite convinced and took it back again for the service manager to listen to and he thought it needed some investigation by his master mechanic. They’ve come back to me again saying normal operational noise. The mechanic said he tried some other, same model and date fiestas to compare and they all made the noise, mine being a middle of the range noise in comparison. When I asked what causes the noise, just got a vague comment that possibly coming from the exhaust area/cat converter. But he tried changing a cat converter on a Ford puma with the same noise before and it made no difference.

Have other Ford Fiesta Ecoboost owners experienced this noise? Thanks

Yes, it comes up on the forum quite often. Yes it would seem that it is quite normal for the 1.0 Ecoboost.

Hi All,

I've just recently purchased a used ford fiesta 2014 ecoboost titanium x. I just recently had the car in the garage due to a service light saying "engine malfunction, service now" in which the garage I brought it into said it was because the oil was diluted and needed changing as well as the vac pump was blocked and needed replacing. I've just had a listen to the engine and noticed a ticking noise and am not sure if this ticking noise is normal for Ford Fiesta's or if it could be due to the timing belt is going? The car has 61k miles on it if that is of any use! I've uploaded a video of the sound.

 

Thanks!

Hi I have a 1.0lt ecoboost 2020 Puma Titanium with 20000 miles on, its the newer chain driven engine, I was wondering if anybody else has the same problem as me. It has a rattleing or tingling noise when starting from cold, it lasts for about 25 seconds then goes, any advice will be appreciated.

Tthis is the video sound below

Hi Debbie,

As you may know, the design of the 1.0 engine changed in 2020 - some cars got the revised engine, some it seems did not - and it would be interesting to know which you have.

Does it look more like the top or bottom pic below?:

Thanks, it’s not the same as the two examples below, more a rhythmic chirp noise and can’t really hear it outside the car or looking at the engine with the bonnet up. Annoying more than anything.

That's interesting. That is the revised engine with the chain driven cam which do tend to be noisier than the other version (bottom pic).

Is there a benefit to having a chain driven cam?

The previous version used a cambelt which runs in oil, known as a wet belt. This has been problematic (check out the number of threads on this site) - the chain so far seems to be more reliable.

Has there been there been a bit of a tizzy with them ?  I'd not noticed 🤣🤣🤣

You're such a tease!

It is interesting though. We originally thought the revised engine went into the Fiesta when MHEV was introduced, then it emerged that some non-MHEV had got into the mix.

Then we found 100ps had continued with wet belt. 

Debbie's is the second 95ps we've seen with revised engine, so it looks like the fairly short-lived 95ps version did get chain cam, then Ford reverted to wet belt 100ps for the lowest power ecoboost.

 

 

Hey! Does it sound like mine Focus on 2000-2400rpm?
