Hello All,

I have had my Audi S3 8v 2017 for about 6 months now. I have only recently noticed it, but when the engine is running there seems to be a loud “ticking/rattling” noise coming from the engine bay.

I see a lot of things online about these cars having high pressure fuel pump’s which can cause this, but was unsure? Last serviced in Feb and nothing noted because of it.

Thanks all- any help or guidance would be greatly appreciated.

I have attached a video for reference (this is when car was warm, but also makes same sound when cold).
