I have a Seat Leon 1.6 BSE 102 HP.
For some time now, I’ve been hearing this noise on a cold start.

It’s a ticking/tapping sound that increases with the RPMs. At first it lasted around 30 seconds, but now it can last up to two minutes.
After those two minutes, the noise disappears and the engine runs perfectly fine, with no errors or other issues.

The sound only comes back after the car has been sitting overnight.

I already tried starting the engine without the accessory belt to rule out the accessories, but the noise is still there.

What could I do to fix it?
