In the Aygo, at speeds above 45mph, there is excessive road-noise, it ain't engine noise, dropping it out of gear the noise remains the same, tyres are correct pressures, (Continentals), anybody overcome this problem, otherwise,

it's a great little car
 
Is the sound there on all roads. We have a Aygo on Continental. You will know if it's a wheel bearing as it will whine.. Jack up each corner and spin wheels, check movement by holding wheel and try up, down, side.

Our Aygo is a 2008, changed one front wheel bearing as it was totally gone. They are split bearing press fit, with circlip. You may need to heat to get circlip out as they get very tight and corroded, need a press to get bearing out and back in.
Also abs sensors get stuck in so may break trying to get out. But these are just a few quid.

Could it be Clutch thrust bearing ?
 
Its a Citroen /Peugeot/Toyota car made in Slovenia with a life span planned for 8 years, it is in all probability the wheel bearings. Just buy the Citroen/Peugeot replacement not the Toyota branded one! All made in the same factory. Our neighbour bought one and was so proud of her *Japanese car* until she discovered a Citroen badge on the rear parcel shelf! It was gone in a week............I am not having a Citroen! Some people! car badge snobs! If it has four wheels, four doors can do about 85mph easily , is at least 4 or 5 star encap rated and cheap insurance road tax and running costs who cares whats on the bonnet!

Especially as it basically is a Toyota. Citroen and Peugeot were allowed to design the headlights. But only on their own models!

Does it change with road surface?. We have had the "new" road surface laid on some roads here recently Much less noisy. Has it always been "noisy", small cars often with lesser Insulation can appear to be noisier?.
 
We have the C1 version (2016) and have no such tyre/road noise, also on Continental, it’s a surprisingly quiet ride for such a little car.
There’s a surprising number of 15 year old one’s running about for a car that according to AC/DC has a planned lifespan of 8 years.

the droning noise starts to come in at around 45mph and increases a bit ta a max at around 60ish, I think a maybe a small car thing? the engine is very quiet, runs like a well-oiled sewing machine
 
Had our C1 for 5 years and it was a bit noisy especially with the back seats down, as we won’t be taking it to Spain anymore changed it on Monday for a Volvo V40 and there is a big difference.

I mean't she might not like it :giggle: .

By the way in case you're tempted to start jacking up the car to check wheel bearings I'd first drive it to see if the noise changes when the car leans on one side or the other when cornering (preferably out of gear & engine off).
 
The problem may be related to tyre wear. I've had it on several cars which are front wheel drive.
The rear tyres do very little work other than when you are braking which leads to the tread blocks wearing more one side(Front to back relative to the car) than the other. Very often this doesn't notice until the rear tyres are transferred to the front when the noise is more apparent. Have you had the tyres swapped axle to axle recently?
Run your hand over the surface of the tread working round the tyre and in both directions. You may well feel that there is a very different "feel" between one direction and the other as your hand brushes over the tread blocks. If you get this noticeable difference it indicates that the tread blocks have worn more like the teeth of a saw and less like the ramparts of a castle.
The only solution is to swap the tyres front to back and even this may not fix the problem, and if it does, only after a few thousand miles. It is a problem with modern tyres which are nearly all directional and so can't be swapped side to side to even the wear.

Hope this helps,

David.

The road noise issue can be lessened with the application of sound deadening, which is limited in many non premium cars. Take the seats out, lift the carpet and add self adhesive sound proofing to the metal floor and maybe part up the firewall.

This is an issue when converting a standard van to a PVC, but on mine, I used the top quality crumbed foam carpet underlay, underneath the carpets. Worked perfectly, but the doors still sounded hollow so added self adhesive panels in there too
 
More work, but sounds promising,Thanks
