Anyone know if it’s possible to do any coding on a 2026 Octavia RS and also is it possible to do some coding to always have the exhaust valve open? When you put it in to S mode the exhaust note changes slightly and I know that on the Golf R it’s possible to code it so the valve is always open no matter what mode is selected

There’s no exhaust valve on the 4.5. Exhaust character in Sport is controlled by the ECU rather than a flap.

My understanding is that the 4.5 has a sports exhaust, no exhaust valve snd no sound actuator. There are some subtle pops on the overrun in sports mode which must be from ECU tuning
