Scored cylinder walls?

[jc07030]

Audi A3 2.0 TDI CRLB engine. Had injectors removed and took a chance to look in cylinder walls with a camera. All 4 of them look like in the picture and video.

Why would there be vertical and horizontal score marks? This can't be normal?

Hi the horizontal lines I would say are honing marks [normal] the vertical marks are not and a sign of oil starvation or cracked piston rings.
