I recently bought a GTC. This morning I took out the car from the garage and switched on exhaust button in comfort, and the valves opened as they should. After going for a ride and back to the garage, I tried switching the button off. The red light on the button went off, but the valves remained open. I tried putting in sport and race mode and back to comfort but to no avail, they just wouldn't close. The red light goes on and off when button is pressed but valves remain open. Anyone here had this issue before please?

 

After a ride, I returned to the garage and tried switching off the button. While the red light on the button went off, the valves remained open, which was unusual.
