N54 making a weird noise! Knock?

Hey guys,

I've kind of worried! Since am new to BMW and switched over from an Evox! My car has 72,000 miles seems every time I turn it on I get this annoying clicking sound coming from underneath the passenger side fender! Almost sounds like a knock it gets quieter once car warms up but never goes alway! Car runs fine no codes and I check my oil every day!! Mods are Jb4, exhaust, intake, dps, charge pipe, and bov! Am I being paranoid! Oh should I take it to a shop! Or say screw!! It and drive it to the wheels fall off!! Lol again thanks! Guys!!

Sounds like wastegate rattle, put it up on jack stands or ramps and have someone start it while you are under the car, listen near the turbos
