2019 RS3 engine ticking sound at idle

[manc_s3]

Anyone got any comments....
I bought a 2019 RS3 from a main dealer 6 months ago.
Its done c.19k.

I have noticed the last couple of days once hot there is an audible ticking sound coming from the engine at idle.
Its never done it before.

If you increase the revs slowly i.e above 1500rpm the sound goes away.
Then once the revs settle back at idle the sound comes back after 3-4 seconds.

It only does it when hot.

Is it normal? Not normal? Its not really loud so I am loathed to put it into the dealer as I know from past experience with noises like this they just say "no fault found".

Advice? Cheers!

Just to add I guess it might be oil pressure related due to the fact it goes away above 1500?

Is it not just the injectors? These cars are direct injection so tend to sound tappy.

Not done it today. Weird. Been out and about for an hour or so and was listening out for it but nothing. Will have to keep my ear out.
