Vw polo 1.2 tsi engine noise.

Hello everyone!
On this video I am working on vw polo 1.2 tsi engine. Car mileage is about 12000km.
Engine code is CBZC. There is a noise coming from the engine. After inspektion and removing of cylinder head, I have found pistons Slap,but there is no wear on cylinders. I have replaced the pistons and the timing chain.
