2015 Jetta Issue (Rattle on idle)

[CannonShane]

So since the day i picked up my Manual TSi Jetta new from the dealer it has made a strange noise when in N at idle, Almost like a slapping/rattle noise that disappears as soon as you put the clutch in.
VW has had the car multiple times and its been "fixed" every time or so they say. Yet the issue still comes back every now and then, Cant really pin point exactly when it does this noise. Car can be warm, cold start etc and it just randomly does it. So far they have put a new clutch in, throw out bearing and even completely replaced the gearbox itself. But its still there. Anyone got any ideas ? Im getting sick of taking the damn thing back, its a new car for god sake.

Well evidently it's not gearbox related.....

Im sure they have got technical involved since they have had to replace a gearbox? Does anyone there have any idea what's going on with it? Can you post a video?

I think I know what noise you are talking about, as I have it intermittently, but hasnt worried me to much as doesnt hinder my driving. I figured was just a sound that happens to be there depending on weather but not sure really. Ive done 11000 in my 2015 jetta no major issues.
Water pump will need to be replaced.
And a window regulator on P/S/F
Other then that goes well.
Let me know what the sound was.

Hopefully this video works, You might have to turn speakers up a bit to hear it, And it doesn't sound as bad in the Video as sitting in the car obviously. https://youtu.be/89f0q_eVxns

Did they find out what it was?

[CannonShane]

Nope. Haven't taken it back there yet lol. They have replaced all of the above and it still does it from time to time.

I dunno could it be water pump? It goes away when the clutch is pushed?

Sound like it could be the dual mass flywheel - they rattle like that when they fail.

[CannonShane]

Could be the flywheel, but you would think after having the box out twice and then also a third time to replace it they would have checked it out.

This is the fuel lines rattling where they route up the firewall into the engine bay. Just had mine re-secured for the second time in my 2013 Jetta DSG.
