Evening, we've noticed a noise with my Son's Citigo that (as far as I know) is fairly recent and would be grateful for any thoughts.

 

While in motion it makes a very intermittent metallic scraping noise.  At first I thought a small stone or similar had got stuck in the brakes as it sounded like that but it seems not, as on our way home today the noise started and cut off immediately that the clutch pedal was pushed in.  Now I'm aware from searching this forum there are reports of the clutch rattling and clonking, but this is definitely more of a metallic scraping noise.  Only happens for a second or so, and only once in a while when driving.

 

Car was bought second hand in August, it's a 16 plate 1 litre petrol if that matters, obviously manual gearbox.  Current mileage is about 16,200 - we bought it with 15k or so on it and it hasn't been used much until the last month or so as son only recently passed his test.  For the record it's made the noise when both he and I have been driving, so not his driving!

 

Am a little concerned as he's potentially about to get a job so will need the car to commute so we need this to be reliable, and I need to know if it's something that's just a feature, or if it needs to go to a garage fairly quickly for investigation.

 

As always thanks for any advice.

If the noise stops when pushing the clutch, I would not assume it is necessarily anything to do with clutch or gearbox (especially as it is intermittent as you say).

The thing is, pushing the clutch in reduces stresses on on the entire driveline...

The noise could be a wheel bearing, or a CV joint but they should be OK at 16K miles. Could even be something belt-driven being noisy on the over-run - alternator/AC/water pump bearing, perhaps...

 

I'd check rear brake drums, and recheck front disks. As often said, noises often come from far away from where you think they originate.
