Had a new fiesta ecoboost for a couple of weeks now and im little concerned with a noise myself and my other half keep hearing from the engine. Basically whenever the RPM goes above 1500rpm the car makes this strange electrical humming/metaly/clicking noise. Hard to explain but as i say only when car goes above 1500. It will also make this noise when parked up and revving the engine gently.
To top it off if driving along and allow the car to slow under engine braking it goes away but if you tap the pedal it will return for a couple of secs then dissapear again.
I have never heard this noise from any car before.
Took it to ford and the guy just said its noisy injectors and is just a new engine design but im not convinced hence why i ask here.
If anyone were able to shed some light on this situation it would be greatly appreciated.
I have put a couple of vids of youtube to demo the noise for you all if you can help.
(very clear metally noise type thing)
(may need to up the volume as iphone mic rubbish lol)
Thanks in advance!
