Performance Exhaust Valve squeak

Anyone dealt with a squeaky exhaust valve on the PE?
Squeaks any time it moves, upon startup and while driving with valve 'open' or PE on to the point it draws attention from bystanders when driven. Doesn't make any noise if not on/valve not opening.
It appears I would have to drop the exhaust to get to the actuators to get a better look, but may still be tough to say.
I have an appointment at dealer in 3 weeks (soonest I can get in, and 245 miles away) and im at 49500 miles... wondering if its worth not driving it for a few weeks to have the issue checked under warranty, or if its a common problem with an easy fix.
Thanks in advance for any advice

Did they end up fixing it? Do your remember what the issue was?
I'm getting this metallic squeak on my amg when pe is enabled. Even on engine start.

Common but good news that it is no big deal though. Please kindly see attached for the bulletin to address this.

Thanks! This is probably my issue on my 2020 c43. I wonder how easy it is to lub the right parts.

They ended up replacing both actuator assemblies as they were corroded (rust) and that was causing the sound. It was under warranty luckily. I have a suspicion the valves retain moisture in the system. I’ll notice it ‘burn’ out some days. I live in and area with fairly dramatic temperature swings and the GLC often makes short commutes rather than highway driving. All a theory though

Was it cover under warranty? I have the same issue on my 2020 C43 I can hear the noise while I drive as well only when the valve is open.
