2013 Volkswagen cc 2.0L CCTA engine. Customer states check engine light is on and runs rough. Codes p0300, p0301,p0302,p0303.noticed on start up misfires are more significant for about 30-45 seconds of runtime. Also noticed loud knocking sound on start up coming from bell housing area. Vehicle has duel mass flywheel and has a duel clutch. I scoped the intake cam sensor Hall effect and the crankshaft position sensor inductive sensor. I have provided a sample from Autel and my scope pattern. I am suspecting something wrong with the pickup on the flywheel I just want to know if my assumption is correct from my scope pattern from someone more knowledgeable in reading them.

To know if there is a correlation issue by looking at the cam and crank patterns, you will need to obtain a known good to compare against. IATN, Diag.net would be my first place to look. Pico or autel may have a library to browse.
The noise you described sounds on track for a flywheel issue, and if the CKP reluctor is on the flywheel, it would make sense that it could skew the cam and crank relationship. I will be the first to admit that I am not very familiar with VW engines
