Metallic clinging noise at startup
Hey guys,
I have this noise, like metal clinging for about 3 seconds when I start the car.. I have the newest software by the way V30or 31 whatever the dealer had at the time when they replaced a fuel pump and insisted I needed a software update.. Is that noise the wastegate noise I keep hearing about or is this something else? Last edited by Ramos; 06-23-2010 at 01:36 PM.. |

rev it up to about 3-4k and while the revs are coming down listen for a metallic rattle noise. this would be wastegate.
p.s. the noise you MIGHT be hearing is just the injectors during cold start. |

haha, it still has a cold start - cold start means the engine and all it's fluids aren't at optimal operating temperature yet. wrapping your car in a blanket wouldn't prevent that

I understand that but I get this noise on warm starts as well.. Turn the car off for a few minutes, turn it back on and I still get that noise..
Anyone else have this issue? |

Does your car always make this noise on startup?

Take it into the dealer. They will probably change our your muffler because the flap is defective. It may get worse... I had mine changed. It was consistantly ticking even after warmed up a month after i started hearing the noise.

it could be the direct injection, i get a very mechanical sound from the car even after being warmed up. you should youtube a video of a stock car and compare the sound with yours

OP, any updates?
Had my software updated to the latest (v34), and ever since, I've noticed this metallic noise at startup as well. I have the performance exhaust so there is no flap. The sound appears to be coming from the front half of the car anyway. Downpipes are stock. ^ Like Sniz, car is MT, and this happens only once in a while and does not occur when revving. |

imho, if you ONLY have this noise during cold start in the morning i would not worry about it.
fwiw, many people with aftermarket dps (like me) have this metal rattle sound for first 4 seconds during start up in the morning. - that is the only time i hear it. ... i also have a slight wastegate ticking while idling - but i have minimal lag - so i donīt mind the noise too much at all. my 2 cents

Can't say it has happened only during a cold start in the morning. It has happened even after a short period of parking. In other words, the car would be driven and fully warmed up, parked for a little while, and upon starting the car again, that metallic noise would be there sometimes.

if you are under warantee - they gotta fix it.
but since you have gotten this noise since the latest ecu update - that to me seems weird. ...who put in your performance exhaust ? if that is the culprit - then the install may not have been perfect - but difficult to say for sure. sorry i cannot help too much

^ Thanks for chiming in though. Was hoping to avoid the dealer.
The performance exhaust was installed a year ago by an experienced muffler shop, and this sound did not exist at all until the recent software update. The noise lasts for only a second and does not happen all the time, but it is indeed strange. It could be nothing, but maybe I should have it checked out. |

I just had my aftermarket exhaust taken off and my stock one put back on. Been noticing a metal rattle sound only during cold starts. It goes away after I start driving. Was it indeed just the exhaust flap for you guys?
