Howdy!
English isn't my first language but I'll try explain my issue as good as I can.
The car is a 2019 Skoda Fabia with the DSG7 with only 2700km's on the clock so essentially new in my world.
This might be a long one...

So this whining noise that Im hearing is appearing whenever I go off the throttle towards a redlight or just slowing down for whatever reason. It seems to be only when the engine breaking occurs and switching down to lower gears and also only when driving 50kmh or less.  I have tried to drive in manual mode and go from high to low rpm's and back on every gear without really hearing the whine. I have tried to push it on incline and such to really push the box. If I would hear it while pushing the gearbox on incline or at any pointwhen accelerating It probably would be a failing bearing but the gearbox is smooth as butter when both launching it really hard or just cruising. However it seems only appear when I just cruise in the city on lower speeds driving as smooth as a taxi driver.

At first I was sure it was coming from the back but the sounds in the cabin can bounce and since its frontwheel drive and the pitch of the sound is higher then any type of wheel bearing failure i've had in the past I kinda started to think that It had to come from the front anyway. I did roll down a hill into a roundabout with neutral in once and I heard the sound, however I havent been able to repeat it. Also I don't think its a matter of bad wheels cause they dont make any sort of "budget wheel" noises at 100kmh.

 

Now I have to add that im allergic to ANY kind of disturbing noise whenever I buy a car, I've had a VW transporter with a manual gearbox that actually ended up having a failing bearing with only 15k km's on the clock.

I found this video of a fabia with even less miles on the clock and the sound im talking about appears on this one as well.

Do you guys have any suggestions on what this might be? Is it just me beeing me searching for faults on every car that I get? Its just a bit to loud to ignore in my world.

 

You can hear it on 1:37 and also very clearly on 2:18.

 

Mine does this as well, from 0km to 130kkm, it is still the same.

Do not get bothered with this whine.

 

Appreciate it, I figured it might be normal on this car since every youtube video with a dsg that I've found has this noise..
It just doesn't sound right to me but I guess I have to live with it!

It bothered me for first 40kkm, but then it did not get any worse, so now i just ignore it.

It's still strange to me cause I feel like Im 100% sure it's coming from the back wich should be imposible unless it's a wheel bearing wich it's not.. Might just be the noise bouncing making it come from the rear.
I think I will be able to ignore it now when I know its on everyones fabia pretty much, just got scared for a second thinking its the dsg breaking down on me.

Could it be to do with the regenerative braking? Do you find that the cabin fan also gets noisier at that same time?

The fan is so silent I wouldn't be able to tell, but it's defenitely when engine breaking with the foot of the pedal mostly. But also when barely touching the pedal at 50km/h no matter if its d5 or d6.

Also when I've tried to listen for the sound I set the fan to zero.

At 2.18 he is not braking. Look at his feet.

He did just start to turn though?

 

Thanks. AG Falco

Exactly, it's not when "you" are breaking its just when you're cruising and the engine does a slight deceleration/Braking. kinda like rolling down a hill with your foot of the gas pedal, exactly what he's doing here 2:18.

These are the other discussions on the energy recovery which could be the whining and fan noise when you set it higher.

I have regeneration disabled and the noise is the same if it is enabled.

How about compared to the sounds in the videos in this forum post? https://www.golfmk7.com/forums/index.php?threads/turbo-whine-of-death-or-paranoia.341434/

It's kind of the same noise, but I cant get the sound while revving it, it never makes a turbo whine/noise when its spooling up on load. It's only when engine is literally cruising or braking and downshifting.  Its strange, yesterday it was cold -13C and i think I noticed it even more even though the car had warmed up and been driven for 20 minutes.

That is called paranoia

leave the noise alone, you will live a happier life if you do 😁

 

Probably, it's just hard not to when thats the kind of noise you wanna keep track of 😅

Update for anyone interrested, I went to the dealer and had him take a ride listening for this sound. The car is going in for a check in 2 weeks. he claimed that it's not a sound thats supposed to be there.. Unfortunately I havent recorded it for you to hear but ill keep this updated anyhow.

Hey @Sund , any updates? I'm having the same exact problem. Noise only occurs on 6th gear on engine braking / deceleration

 

I don't know the exact speed that it does happen but it's between 30-40mph 6th gear , in 4th gear you can notice a slight noise but nothing major.

 

As soon as it goes in 5th noise goes away.

 

Thanks in advance
