Hi,

 

Can anyone help me please?

I have a new - to me - 2015 1.4 Petrol AWD yeti. Been driving it for about 1 month and can hear a whining/transmission type noise at 60MPG. The noise goes at just after 60PG, but comes back again at 60MPG as my speed decreases, then it goes again below 60MPG. Skoda said it was down to mismatched tyres on the rear axle. I've changed those now, still have the noise 😞 so now have 2 good tyres going spare, if anyone would like to take them off my hands for a small consideration. I have noticed though, since the new tyre that I can hear a very faint whining noise at just under 40MPG which I cant remember hearing before. The car is going back to the place of purchase on Tuesday as the fault came with the car for them to inspect and hopefully put right. 

If anyone has any ideas please that I can pass onto them. Also, if its just that AWD cars make this noise, then I would also like to know, then I can tune the noise out when I'm driving. Although it is annoying as it is at 60MPG. Lastly, it has occurred to me that the car is just very sensitive, and doesn't like that it has different tyres on the front and rears axles. Although they now match in both make and tread on each axle. Could this be it? Skoda said that it doesn't matter about there being different makes front and rear, just as long as the axles have matching tyres. I'm am reluctant to put another set of tyres on the front only to find that it makes no difference, especially as the front tyres are new, all be it a economy brand.

 

Any ideas greatly appreciated.

I have the same car and to date have never noticed any whine at any speed? Still running the same 4 tyres as fitted when new as only 18k miles so far.

 

.....although I can only get 42mpg out of mine so you are doing well if you can get 60mpg

Presume you mean MPH.

 

Tyres can wear unevenly, especially on the inside edges of the rear tyres.

You can notice a sawtooth pattern the the tyre tread.

Some tyres are noisier than others?

 

Sometimes you can swap the tyres from side to side to alleviate this.

Yon cannot do this if you have directional tyres.

 

To tell if it is the tyre or transmission noise you can try this.

Does the car make the noise if the car is 'driven' with all the wheels off the ground. ( on a garage ramp )

So you have no tyre noise but the transmission is still moving.

Or does it only happen when the tyres touch the ground?

 

Might you want the tyres at a later date/time.

People might want to know the size of the tyre?

 

Thanks AG Falco

added noise bit.

Is the Haldex oil/filter change overdue - should be done 40,000 miles?

 

If bought from a trader (not private) - take it back for them to sort. You have rights - taken from the AA web site https://www.theaa.com/car-buying/legal-rights

Between 30 days and 6 months

If a fault comes to light after 30 days but before 6 months you’re entitled to a repair, replacement or refund.

• It’s assumed in law that the fault was present at the time of purchase unless the seller can prove otherwise.
• Unless you’ve agreed otherwise, the seller (dealer) has only one opportunity to repair (or replace) the faulty vehicle after which, if they fail to repair it, you’re entitled to a refund.
• In the event of a refund following a failed attempt at repair during the first six months the seller may make a 'reasonable' adjustment to the amount refunded to take account of the use that you’ve had of the vehicle.

Hi,

Yes I do mean MPH! 60 MPG if only!

I had hoped that Skoda would have run the car on the ramp, but seemingly not. I will make sure that the garage its going to on Tuesday do this though thanks.

The tyres are good, no sawtooth pattern.

Hi BigJohn,

 

The Haldex oil was changed at 17,000, although not the filter I think mention of that anyway. The car now has 21,000, although the noise was evident at 19,000.

What tyres are fitted?
What pressures are you running them at?
Have you checked ALL the wheel bearings?

 

The fact that the noise seems to be coming from the back means nothing, I'm afraid. Noises in cars can come form all sorts of places.

Hi Lianigraham,

 

Cooper Zeon 225/50 R17 on rear. Brand new. Suhitrig - I think on the front, also new. Tyre pressures as set by the garage. Its just passed its MOT and been serviced, so I doubt wheel bearings.

Cooper's aren't known as being the quietest tyres and I can find no trace of that make on the front, so am very doubtful about them.
The garage might have done the tyre pressures, but have they done them correctly? Always worth checking. I know that if I have mine higher at the back for towing they are a lot louder. (Correct tyre pressures are inside the fuel flap)

I'll check that thanks

..I get a whining noise over about 70, but only when accompanied by spouse !

often speed related issues point to wheel balance which if the shock absorbers are also a bit weak could cause some additional noise. To be honest it could be almost anything but prop shaft, wheel bearings or tyres would be worth checking. Try swopping wheels front to back? See if this changes anything.

Rear Tyres - ruled out

Haldex

Rear Diff

Wheel Bearing

 

If the front tyres are Sunitrac then even if they can't be attributed to the noise then get them swapped.

 

They are the cheapest tyre available on the market today. Whoever bought them had no consideration other than to make the car legal.

 

Whilst I'm not an advocate of buying premium branded tyres, I'd also recommend staying away from the very bottom end too. 

Trusting driving with Tyre pressures set by someone you do not know and who does not know you is very risky.

Even leaving them to reset the TPMS is just not worth it.

Are these two threads linked?

 

Is so then the "metallic grating" adds a potentially different dynamic to the problem.

 

Any metallic noises should be identified ASAP.

 

It might be a loose exhaust heat shield, but it could equally be metal on metal contact, without sufficient lubrication...

 

 

So, its been a while. I took the car back to Skoda in Norwich for a 3rd time. Incidentally, they have not charged me for these tests, and have always washed my car and taxied me to and from work. Can't recommend this dealership enough, wish I'd got the car from them. But I digress. They noticed some marks around the gearbox so decided to investigate. They drained some oil from the gearbox, and it came out black and sparkly!!! Clearly this is not as it should be, and it is now quite clear that my whining noise is coming from the gearbox.

So on the one hand this is good news, as now I know what the problem is, but on the other, oh my god!!!!

Went back to the dealer I got the car from and quoted the Consumer Act at them. Its taken a while, but they are collecting it this week and hopefully will return it to me less a whining noise now we all know what the problem is. Also noticed this week that my sunroof is leaking, which does finally explain why the car smelled musty when I got it. They will also be attempting a fix here, although I am not that hopeful. Now that I am aware of my rights I may still reject the car. So watch this space.

Thank you all for your useful suggestions especially from bigjohn.

seems this car is not so much a white yeti, but a white elephant!
