My Mk6 1.4 Fiesta makes this weird noise at idle, but only after the engines warmed up (2 or more miles of driving).

 

Pushing the clutch in has no effect on the noise, but it does go away as soon as I give it a bit of gas and comes back again once the revs drop below 1k.

 

Its sort of like a low pitch 'brrrrrrrr', if that makes sense.

 

I can only really hear it when I'm in the car, but I'm not sure where its coming from.

 

I recorded a video of it to show what I mean.

Anyone know what it might be?

Sounds pretty normal to me, check the coolant level to make sure the pump isn't leaking otherwise sounds fairly quiet, out of interest what does yours sound like after starting it from cold?

Coolant's all good, so it can't be that.

 

Starting from cold sounds normal; begins at around 1.5k before settling down to 1k after warming up.

Then drive for a mile or two and stop/coast with revs below 1k and foot off the gas and that 'noise' is there again.

 

If you watch my video again with headphones in, you can hear the noise more clearly.

 

Don't suppose you could record a vid of your's idling so I have something to compare with?

I have got to pick the old maid up from work a bit later I will try to remember to record her when I'm outside there, do you want the little weave toward the dashboard on the passenger side or just record and hope?

No weaving necessary lol, just a simple recording from the drivers seat will suffice.  :D

 

Thanks again Nathan,

I had a little weave, she's upto apparent optimum temperature on the gauge, some of the tapping is the rain. Good old cornish night, not.

Seems very quiet, the mic used is on my phone with hd voice switched on, if it's no use and you can wait till its not raining I may be able to get another.

Ha ye, I know what ya mean about the rain lol. Got my car just in time before all this s**** weather begins.

 

Cheers for the vid; I think I can slightly hear the noise very similar to mine, just not as audible (maybe its the different mics?).

 

Don't suppose you'd be able to do another one with a couple of revs applied at intervals to hear whether it disappears and then re-appears etc?

 

Sorry to be a complete pita, but I'm always ocd when it comes to things like this.  :lol:

Yeh I am like this as well, hence the question about cold start up does yours sound just a tad rattly or tappy for just about a minute? I think the noise you talk about is the solid lifters as it would just blend In with the revs being higher, as far as I know it would be similar to your sound but I don't really notice it until I go down a hill in 2nd slowly close to my house when you can hear it. I find it to be lovely and quiet while warm but diggery tractor like when cold, pretty decent unit though if a little lazy at lower revs.

Tbh I can't say I've really noticed anything out-the-ordinary when starting from cold, but I'd be more than happy to record a cold startup if it would help in any way.

Yeh that would be great I will try to remember to get you another recording, maybe sometime next week when I'm driving to work, I have looked on YouTube and found a few that do it, it's only when cold not warm so it may well be current across all of the sigma/se engines. If it ain't broke I'm not considering fixing it anyway.
Time for bed I believe, cheers and gone.

I have 2 more videos here for you, one is with the revving that you wanted and the other is just idling again hopefully it will be more audible.

Cheers for that Nathan, appreciate it.

 

Your's does seem to make the exact same sound, and mine's done twice as many miles, so it must just be a Fiesta 'trait'.  :D

 

I can probably record that startup for you tomorrow. Driver's seat or bonnet up?

Just from the inside will do its not so audible outside, the noise goes away after a minute I think it's either exhaust or injectors but I have heard it in other videos, it's a poor sounding engine really for what I would call a modern unit it's pretty 60s sounding haha.>_>

Here's that video of a cold startup you asked about.

Hopefully that torrential rain can't be heard too much.

Sounds exactly like mine with the tac tac noise for about a minute, mine is normal, yay.:D

I will see if I can listen again later on the computer I'm still at work, I guess we are both worry free for now, how far down Cornwall are you?
