I could hear it at 40 but louder as I got up to 60 and faded around 70

@Bobbymahonalso the noise is audible from around 40 mph upwards. 

 

What gear and what engine speed.  If it's most noticable around 2300rpm and in higher gears then I'd wager at that mileage it's the rear propshaft coupling that's worn and needs replacing.

Good question, I'll have to look into the gears / rpm tbh as I wasn't being that scientific. I've read about the coupling and was going to get that checked, would that be visibly worn if the car was on ramps do you know?

Thanks. 

It might well be visibly rusty and a bit the worse for the wear looking. 

Thanks Toot, I'm currently driving around Scotland on our honeymoon (Skoda forum hidden from wife) I'll get that checked out when we're back.

So a garage messed up a service and then denied it? Who do you use now, a indie VAG specialist or main dealer.

 

I feel your pain, you still love your car though? 

 

No it was me who screwed up so I cannot deny it 😳

 

I even had a fellow Briskodian as a wing man because my vision is not so good, we both thought the logical drain plug was the one beneath the filler plug, I knew people had got it wrong so we were being cautious, I was in the UK & the computer in France so I could not look at any schematics.

 

I still do all my own repairs screw ups! 😆

 

And still in love with the vehicle, did a spirited drive on empty roads this morning, rare that I am in the mood and the conditions allow it, fast but very smooth, in fact the car seems to ride better over bumpy chemin rurales when driven faster.

 

I have the rear seats out carrying tools & 5 bags of concrete so could hear the transmission noise this evening.

Re the coupling, dont be alarmed to see that there are circumferential splits and the outer ring looks like it is about to detach, they will be suspiciously regular in their irregularity, like a waveform, I bought a new coupling only to find that the seperation is part of the design and the new one looks identical.

 

I have yet to fit it as the engine has to be moved forward & now am happier with the old one, so is my CT inspector (French MOT) who had failed it when i pointed it out to him. It is possible that the noise may be reduced when I do get around to fitting it.

 

Its a harmonic balancer and the outer mass is intended to be decoupled from the inner drive portion like a harmonic crankshaft pulley, even were it to completely seperate the driveline would not be compromised.

Nothing ventured and all that…

 

Fair play for trying, I used to enjoy tinkering when I was a lad but I stay clear of most things due to a lack of skill and enthusiasm (I have a transit which I weld things back onto every year though).

 

We have just driven up some very rugged single track road in the North West Highlands, the car feels very planted and good in the snowy bits!

Thanks for the comprehensive explanation! So it’s not a 10 minute job then  

 

Maybe a visual inspection to begin with… 

 

There’s worse places to be, lucky coupling.

So my noise is constant and can be heard above 30mph (most audible around 40 / 50mph when road noise isn’t too loud but the resonance makes it noticeable at higher speeds (to me, not the wife). 

 

Seems to be independent of gearing and engine and rpm and I’m not sure that gear changes etc make a difference - I.e more relatable to speed / rotation - still present with clutch depressed.

 

I could be wrong, any advice on how to test? Starting to doubt the relationship between my ears and brain. 
 

Skoda described it as on overrun which is apt.

That doesn't sound like the propshaft coupling then.  When ours went it was very related to a specific engine rpm regardless of speed but was more noticeable in higher gears under load, particularly in top at 75mph ish but tailed off at the same speed with the clutch depressed from memory.
