I've been noticing a strange rattling sound from the adaptive suspension and honestly it feels like a completely different car.

Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune and it completely bricked the module. Have you checked the fluid levels? That's usually the first sign of trouble.
