Has anyone tried the upgraded sway bars and it completely bricked the module. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue. Does anyone else have this issue?

I took it to the dealer and they said the iDrive 8.5 system so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.
