My car has developed a rattle on cold startup which from reading on the forum is most likely the cam chain tensioner. There is also a rattling noise coming from the engine only when the engine is warm and under low revs between 1.5k to 3.5k.
The noise is coming on under low revs in neutral as well as in gear.
The car is on 86k and has recently had a 10k service. Previous owner (8 years) to me has serviced the car every year and has on average covered around 6k miles between services. I have also recently had the oil pick up pipe checked which was fine and not blocked.
The car appears to otherwise drive fine, engine pulls well,no flat spots etc...
If there is anymore info you need to know please ask.
Here are a couple of videos below, one for cold startup and the other with light in-gear acceleration.
Audi 8L S3 - Startup noise when engine cold. - YouTube - Cold startup noise.
Audi S3 engine noise under load - YouTube - Noise when revved in gear and in neutral.
Any advice is much appreciated
