Wastegate rattle most likely.
First post.
Firstly picked up my 40 only last week. Really happy with it, my first VW.
Only qualm I have is there seems to be a faint-ish rattle coming from the engine bay only when the engine is under load. Particularly between 2-3.5K RPM.
It almost sounds like someone is dragging a chain on a tin surface, except they are half a K down the road haha. Weird I know. I can't replicate the sound when the car is not moving.
Anyone else experienced this? If so what is the fix? This is a MY16 40th built in June.
I am taking it back to VW on Friday anyway. Only 250ks done.
Can't fault the car in any other way - but for 50K you would expect better.
Comments appreciated.

Geez, you'd thunk they would have gotten the hang of this after 4 years!
Does it sound like this by any chance?

Like a vibration becoming apparent around 2.5k and then disappearing? if it is that, that's the fuel lines not the waste-gate.
It certainly sounds like you're describing the wastegate rattle that affects almost all cars with this engine/turbo combo (Golf R, Audi S3, etc etc).

2005 MkV Volkswagen Golf 2.0 FSI Auto

Sold: 2010 MkVI Volkswagen Golf GTI DSG
Anyone know if there is a TPI/TSB for this for the mk7 ? I have not heard of it to date. Bugger ... check these out:
* Fuel lines
* Wastegate rattle (was an mk6 issue .. not again!)
* Soundaktor (more of a buzzing sound, maybe not related)
rattling noise under the dash acceleration. - GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum
VWVortex.com - Question about soundaktor
There was a lot of mucking around with the clips on the Mk6 with dealers feigning ignorance etc.
Hope you get it sorted out.

Thanks for the replies guys. I will not accept VW telling me this sound is normal. Will keep you all posted.
I read elsewhere the downpipe could also be the culprit? Does anyone else own a 7 gti or r with this issue?

^ The way you describe it GTI40 sounds exactly like the Wastegate rattle many R's (but not all!) have: as the GTI40 effectively shares the R's motor, one would expect similar proportions of GTI40's to have the rattle. There are a couple of guys here who have replaced their DP with good effect however this also requires a software tune (Stage 2) and loss of drivetrain warranty (not too mention $3-3.5k of further expenditure). I have however read on UK forums of a few people who havent had success with the DP replacement removing the rattle. I wasn't prepared to do this with my Wolfsburg R, and was absolutely stonewalled by VWA so ended up selling it as the sound ruined the experience for me.
