Hey guys

I have a Audi A4, 2005 B7

When from a cold start I get this annoying startup rattle for 1-2 seconds then it's gone. Engine is very quiet after this initial rattle. Car drives fine etc.

As I am aware this is a widespread problem but nobody has a definitive answer to solve this.

I have been driving like this for 2 years now.

We had the engine open the other day and there is no indication of wear or anything. Engine looks super clean.

Here is a link. My engine sounds precisely like it:

Any help would be very much appreciated.

Thanks

That is quite a rattle! It could be the hydraulic lifters but I've never heard them that loud or stop that fast.

Have you tried changing the weight of the oil?
