Wastegate Rattle

Hi Guys

So I fitted a DP, DCI, charge pipe, BOV and finally a JB4 G5 iso.
Just after fitting the JB4 I started to get wastegate rattle.
It an E92 N54 with 97000km. Out of motorplan.
So far I got mixed opinions.
BMW wants just over R30k to replace them


Has anybody had/have this prob and lived with it for a while?
Does this mean my turbos are on their way out?
What are my options here guys?

Thanks!
