Strange High Pitch Whistle/whine When Accelerating

Recommended Posts

Hello everyone! 6 weeks ago I bought my first car, a 2009 mk7 1.25 Zetec Fiesta (approx 50,000 miles)

I love to bits but have noticed a few niggles which I thought someone may recognise or have some ideas on what they could be:

1) When accelerating I often hear a high pitch whine or whistle kick in (sounds like something spinning) which usually happens at 2500 - 3000 rpm. Taking my foot of the accelerator a little stops the noise but it may come back when accelerating again. It sounds like it is coming from in front of me when driving but it is hard to pin point.

Possibly wear and tear on something spinning or I may be totally wrong!

2) secondly, after driving for 5 minutes or so the gear stick gets quite squeaky and harder to move when moving the stick down (1st to 2nd or 3rd to 4th)

Has anyone experienced either of these and were they costly to fix?

Thanks :-)

Phil

The gear stick one is probably just some dry rubber parts in the linkage, I'm sure there used to be a thing on here about greasing it up, and the zse engine and gearbox are both a bit whiney so I would say it's alright to be fair.

I mean my fiesta is a bit whiney but so was the one I learnt in and so are any others I have been in so I'm pretty sure it's not the end of the world, depends what your used to I guess.

Yeah, I guess it is a case of when you hear it for the first time you always listen out for it next time! It's a kind of spinning whistle noise, hard to explain. I'll try and make a video or recording and upload it.

I've made a short audio recording of the sound. You may need to turn the volume up as my phone struggled to pick it out (sounds louder in real life) but hopefully this will be more helpful.

It's a very high pitch spinning kind of noise that kicks in between 2500 and 3000 rpm approximately. Thanks!

Is the whining more pronounced in second gear?

Sounds like mine. Have found myself wondering what it is so booked in to the garage for them to have a look at

Hi Phil,

What was the problem in the end as my Fiesta has just started to do the same?

Thanks, Jordan

Hi Jordan,

Did you ever find out what the problem was?

I just took my car for its 5th annual service and they did a cam service too but I see that they didnt replace the fuel filter. Thought the cam service might solve the issue but it didnt :(

Spoke to a mechanic mate of mine and he said it could possibly be the fuel filter??? Slightly annoying but but hope its nothing major.

Thanks

Mike

I have a similar whine in my 2014 Ecoboost Fiesta, mainly in hotter weather and when accelerating. According to others on here it could be an alternator issue, the fault is so intermittent that when I took it to the garage they found nothing. However, on longer trips it can sometimes be heard especially with the aircon on. As for gears  Itend to find if the car has not been used for a while then 3rd gear is a little stiffer to get into, but that could just be me.
