Oh god, that sounds awful! Sounds like crunching gears but I'm assuming your not working the 'box. Surely someone here will know.

Does it only happen when the engine is cold, or even when it's warm? If it's cold it could just be a rich mixture or something – mum's Megane makes a sort of similar noise when it's started cold and revved a little.
Otherwise, I have no clue.

If this car is a DSG variant then that's not a rattle (the sound is too blunt / muffled to be metallic), if I'm correct that's the hemolitz chamber in the exhaust system. How ever do you think DSG cars get the fart / blurt upon gear changes?

The fart noise is caused by the ECU pulling ignition timing when the DSG shifts.

It does it when the car is cold and warm, so basically all the time lol.

My Polo is 6sp Manual, it happens when i'm driving occasionally too, the car was in neutral and i was just lightly tapping the accelerator

My Polo's Manual.

Book it in asap. For a manual that's quite strange!

[Snail Style]

Hows the idle/engine operation? There was an update for those relating to cylinder 1 & 4 misfiring sporadically.

P.s the DSG farting wasn't addressed to you OP.

Booked it in at Blacktown VW (where I bought it from) for the 23/4,

Engine idle/operation is perfect, I have had no issues whatsoever, apart from my door lock screwing with my head, which was fixed.

Ooooh okay, I'm actually glad I didn't get the DSG in the polo, my previous Holden Cruze (LEMON) was automagic (magic that an auto transmission will fail more than 4 times in 39,000 kms/1year.

Sorry to steal your thread OP, the title seemed appropriate.

Would anyone happen to have a recording of what a normal 1.2 TSI engine should sound like at idle. I get paranoid every time I open the cars hood cause it sounds like a timing chain rattle. Its a 2010 model and I'm guessing its out of warranty.

Sorry to steal the tread back from you, kar2390.

Upon visiting my dealership today, I was advised that my car is completely within "perfect working parametres", so basically, the noise is completely normal. They could not replicate the noise on another Polo, although mine was perfectly audible.

I was also advised that there may be a little moisture in the catalytic converter caused by me not driving my vehicle hard enough. I was told to drive my car harder, and a vehicles engine is designed to reach the 6000rpm limit, therefore should reach at least 3500-4000rpm before every shift..... Sorry, was I just asked to drive my car up to 6000rpm...?! I rarely go over 2800, which is perfectly reasonable for ANY vehicle!

Upon gathering this information I got straight on the phone to VW customer care Australia, and was told not to follow the advice and go get a second opinion, which I will do... Upon gaining the second opinion, and the abnormal noise issue still being present, I am to call again and optain a case manager who can correspond with the dealership and tell them what to do until the issue is resolved.

I believe that people like me, show up to a dealership, they plug it into the computer. Upon doing so, if it returns normal, that's it, no more investigation will be undertaken. That is really really frustrating.

It probably is a timing chain rattle. My 2011 Polo 77Tsi 7Speed DSG had a timing chain and tensioner replacement at 70000Km.

Its just ticked over 102000Km and it sounds like another chain/tensioner is needing replacement

If you look around the top plastic part of the timing cover you can see the poor job they did when VW service department replaced it at 70000km. How hard is it to wipe away the excess solastic when its wet.

I have just discovered today the Service Department has been using Valvoline "Durablend" oil in my car.........Can anyone tell me if this oli is approved for use with my car

Can you tell me mate, how often will it make this noise?

Is it every start up / when it's cold / when it's hot etc. I have a noise that sounds similar but not the exact same. Yours goes for much longer than mine by about 3 seconds and then fades out where mine just stops which leads me to believe that it's the turbo wastegate not the timing chain, but still some information would be useful in diagnosing it.
