Few sounds from the S3?

[JD09]

Hi all,

Couple of recent sounds from the S3 (now I've decided to keep the damn thing!);

1. revving above 3k when cold (rarely do it, just noted it the other day), I can hear a tinny, metallic sound - sounds like the exhaust is very cold but haven't noticed it before... goes away when it warms up... doesn't sound rattly, like anything is loose though? It sounds like someone revving a really cold car on one of those "look at my new M3 I'm about to break due to revving from cold" videos on Youtube!!!
2. when coming down through the gears, if I lift off in third and the revs drop it vibrates a little - it doesn't do so when gears are not engaged... gearbox? Not sure when the last gearbox oil change was done, so would you lot suggest that as my first port of call?

Will log it for errors tonight and update if anything shows.

Cheers all,

Jamie

Also, did a quick search in Google for "Vibrations as revs drop" and a Porsche forum (I know!) mentioned the flywheel being a bit knackered.

The "issue" has only starting happening recently - car is mapped stg 1 and the clutch has never been replaced so have a feeling it might also be on it's way out...!

Could it also possibly be the dog bone mount worn?

I'd bebstarting with the dog bone rear mount bush myself.

£17 quid for a powerflex one. Worth doing even if it doesn't fix it.

Could that rattle be the heat shield on the exhaust? (Think that's quite common - mine certainly does)

My heat shield on the bottom of the cat used to rattle from cold, soon got underneath and ripped it off!

Cheers Dan, I'll have a gander.

+1 on the dogbone mount, swap it for a red diesel one and you wont tell the difference from standard but they last a hell of a lot longer, unless you're building a track slag, then go for the yellow one

Next step would be check all your heat-shields under the car to make sure all the screws are still in because they do tend to rust... Then the last thing would point to the DMF :/ let's hope it's not...

Hi guys,

Sorry to bump!

So the exhaust rattle sound has now started to be a tinny "exhaust is loose" sound. But only on startup i.e. when the car is cold... as soon as it warms up, it runs with no sound.

Now I'm kinda hoping it is the exhaust and I sadly have to get a new OEM+ one! But are there any other suggestions? Car is also a little juddery from start up/cold. Last time, this was the MAF... remind me of how to test this? Unplug it?

I'll be logging tonight.

Mine sounds abit tinny on start up but that's just the car overfueling to warm up! Pm me your number and ill send you a video if what mine sounds like. See if it sounds the same?

 

[JD09]

Done, cheers buddy. This is defo a loose cover or exhaust part sadly...

My heat shield above the cat is rattling, and only does it when cold, have you had a look at that one?
