Hi guys. Got a 06 plate skoda fabia vrs pd130. Ive noticed a noise coming from the gearbox, It's mainly in third but can hear it in low rev's in forth and at about 2000revs in second.

 

Can only hear it when the car is under engine breaking at around 2000 - 2300 revs.

 

If I had to explain the noise its kind of a mixture between whirring and rattling :(

 

Really hard to explain but it defiantly doesn't sound healthy :(

 

Any advice would be appreciated ???

Also, When I put the clutch in, It doesn't make a noise?

When havr you last changed your oil ?

I recommend changing your oil as soon as you can

Allot of people neglect to change gearbox oils till its too late

Most likely going to be you're dual mass flywheel. And a possible release bearing causing those issues mate. Not cheap but necessary unfortunately.

DMF.

 

That is all.

The DMF bites again, pieces of ****...

B***CKS!

 

Any dual mass flywheels recommended? :/

What kind of noise?

Is it a whine? If so my money is on the diff

My leon was the same

start with the easiest/ cheapest things first. Drop the gearbox oil and renew. Any juddering when releasing the clutch?

Nope no juddering. It's coming from the passenger footwell, and only does it when the car is under engine braking? It's weird. I'll try put a video up of it so you can hear the noise.

Take it to a garage? Unless we can 100% pinpoint the problem on here from your discription and video you would be better getting a decent indi to diagnose it than throw parts at it.

For 20 quid. Try changing gearbox oil first . Only a ten min job

Dual mass woukd make a noise when sitting on spot. That sound is drive related. .... so somewhere in gearbox

New flywheel and clutch .. 1000 ish

Gearbox 600? Ish

Gearbox oil 20 quid

Cheapest quickest first

fletch101 what you're saying doesn't make any sense at all from an engineering point of view, if the oil level were low the OP'd have trouble changing gear smoothly.

 

The noise that the OP is hearing is the sound of a mechanical part failing, anyone who knows anything about these cars knows that the DMF is the primary suspect because it's a known weakness.

 

A failing DMF is really difficult to diagnose because you can't see it to inspect it, you can only listen to it, talking rubbish about changing the gearbox oil just reinforces the denial process and exacerbates the problem because the DMF is failing but it hasn't actually failed yet, the longer the car is used the worse it'll get until it goes bang and renders the car unusable.

 

You can listen to the DMF while the car is on tickover by putting your ear to a screwdriver touching the bellhousing, get a mate to press the clutch while you listen and note the difference.

 

You can apply the same technique to the gearbox, if a layshaft bearing is breaking up then you should be able to hear it by putting the car on axle stands and engaging a gear while listening to the gearbox.

 

Either way the gearbox is going to have to come off unless a driveshaft inner joint is failing which is very unlikely.

Alls I can say. Dual mass flywheels get diagnosed while at tick over not during overrun in gear.

Mine had a 'noise' during the same conditions when I bought it. Put fresh gearbox oil in and it sorted it (old stuff was like wd40 coming out)

And with it being a particular rev and speed range I would say gearbox.

Flywheel would be rev related and do it in every gear at same rpm

Im speaking as a mechanic . Although im not a fabia expert. I speak with general experience

20 pound and half hour of time is a good gamble rather than gearbox out job. Pluss either way gearbox oil should be changed sometime. ..

Makes sense to me

Ps: gearbox oil degrades over time... temperature changes. Being under load. Humidity.

Btw he would only have trouble selecting gears if the Synco's were on their way out not if any of the bearings were getting a little worn

Rolling the dice is never smart fletch, diagnose the problem correctly and repair it. Being a fitter by trade you should know that a big bill is usually unavoidable when it comes to clutches/gearboxes.

It's not really rolling a dice though. . From what op has described . Its gearbox related. .

Ok on idle. Not mentioned noises or lumpiness on idle which are the common fly wheel issues. ...

So its gearbox 90% sure of it.

And the first thing to try is gearbox oil. As most people neglect to change it often enough

So rather than spend 1000 straight away. Spend 20 quid. .. even if it geta him 10 thousand more miles out of the gearbox its time to save up

To me its a no brainer. Done it on both my cars and its saved the gearbox.

Technician not fitter btw and sometimes its best to take our best educated guesses based on the symptoms we know. And an oil change will do no harm and is do able by anyone athome

Also if you look . I am not the only one to say it's probably not the flywheel.

With a bit of luck we shall find out how the problem develops/ is solved

That's strange my dying dmf didn't make much noise when driving but on idle it was horrendous.

If you know what a dual mass flywheel is. You will know wheb not underload its 'bouncing' back and forth within its travel thus making the noise and knocking the car.

Under load it is 'pinned' to the end of its travel thus effectively becoming one solid state moving as one . So no noise or bumping ...

And person is describing symptoms under load not standing still . Make your own educated guess to where it is coming from after reading that.

Not sure if you were aiming that at me but I was agreeing with you with my initial post :P

Nooo not you dan. You supported my theory haha

It wasnt "aimed" at anyone. As no names or quotes in my post.

Just pointed out how I come to my conclusion to those who thought I rolled a dice. ...

Oh and if anyone finds a dice with possible faults written on it. Its mine and would love to get it back

Cheers for all the advice guys. Luckily my cousin and uncle are mechanics, taking it to there garage for them to diagnose the problem tomorrow. Hopefully, its just something silly, if not then I guess that's the problem with buying a second hand car, and i'll just have to get on with life. So Yeah, will update you as you all seem pretty interested as to what the noise is. :(

 

My cousin thinks is 90% its the bearings in the gearbox. as its in three gears out of 6..

 

Will find out tomorrow.

 

 

Once again thanks for all the advice, Really appreciated !

Very unusual to have a vrs box with bearing issues as they are a strong box, we see loads of dmf issues and normally the symptoms are knocking noises at idle and or clutch judder when setting off (clutch judder is when the dmf has seized). your best bet is to take it to a garage as diagnosis over the net is hard and could become costly with a miss diagnosis.

Exactly what I thought. Soon find out tomorrow. :(

 

Poorly Fab :(
