S3 Sounds Like A Diesel On Startup....

[Aliworlidge]

I've got a 1.8T quattro which is the same basic engine and i get the same noise when starting, sounds like its quite common by reading this post. It instantly goes away though, if we've all having the same things then maybe its normal??

yeah my 1.8T does this too, I don't worry about it any more. I think it's just a pulley or tensioner rattling.

i've got an s3 1999 and it sounds like a diesel on every start up. It is common so dont worry about it. When i leave i usually say lets start up the diesel. gets peole thinking when i do start it up tho!

Change the oil filter to the modified larger filter.If only briefly occuring it is infact normal and no damage occuring,the advance/retard sender at the camshaft rear chain tensioner is adjusting to cold start command and trying to build oil pressure as fast as possible.But oil sludge is another issue hence modified filter size.Also consider having the sump removed and the oil pump strainer cleaned out to increase oil pressure/feed.

it could be your that your oil pump is not sucking sufficent oil up to the top of the engine on starting you may need to take the sump off and have a look to make sure there are no particles blocking this off restricting the flow of oil at first turn over

my mine also does it i have a 2001 s3 i dont even think if as long as 2 second its the second i turn the engine over then its back to a nice low growl i asked the guys that tune my car they said its just the sound of the audi engine starting up no problem at all so i wouldnt worrie m8 aslong as u get your oil and filter changed every 6k or so your engine will be fine
