RS5 exhaust flap

Post by Fonzi97 » Mon Aug 06, 2018 1:40 pm

Hi all, I need some advice please 🙏🏻
I have recently bought an Audi RS5, when in dynamic mode only the drivers side exhaust flap opens up, is this ok or is it a fault?

Sounds faulty, what model year is your RS5?

They should both open the same time. The motors themselves can be bought direct through Audi, but the valves are part of the exhaust system so hopefully its not seized. Check the wiring to the connector.

They are quite simple but the motors do have an error signal if something isn't right. VCDS should pick it up if there is a problem. People sometimes disconnect the electrical connectors when the flaps are open to leave the cars in loud mode, but this would bring up an error - maybe Check Engine Light.

Actually scrub that, they might be vacuum operated on the RS5. Have a gander underneath and see if there is a rubber hose connected. You could just have a split pipe.

You sure they are both meant to open at the same time? I thought I read the latest gen RS cars can open one flap then the other.
