Hi Guys, Recently bought a second hand R8 and the guy who sold it to me didn’t really know all too much about it. When I got the car keys it has this fob attached to it, but I have no idea what it does. Anyone know what it is?

Looks like either a garage remote or to open an electric gate mate. I’ve got one like it for work entrance

Yep that's for a Capristo exhaust! What a great bonus you didn't know was on there! They are about £5-6k fitted I think.
I have it on mine, button 1: valves closed until 5k revs, button 4: valves fully open all the time.

Ahh amazing, definitely an added bonus. Thanks for the help guys!
Do people know the exact functions of 1, 2, 3 and 4?

Taken from the Capristo manual:

By pressing the buttons 1, 2 or 4 the device will switch between the different
modes. In cruise mode (button 1), the valves open at higher engnie power.
In sport mode this already happens at lower backpressure. Button 4 open the
valves permanently.
The internal radio transmitter is tuned to 88.1 MHz. It can display
information on the radio‘s display. With button 3 you can switches between
different screens. So you can display the current mode, the pressure or
overall status. Setup functions are also possible using the radio display.

Whaaaat! I had no idea. Does this work on the basis MMI RNS-E 2G do you know?

it depends on how that particular exhaust has been programmed, it could be set up in various ways...
Just Press the different buttons and you'll figure out how they have it set up. One of the buttons will almost definitely be set to have have valves fully open though.
The pressure the valves open at on other buttons will depend on what they chose when they set it up.
