DISCLAIMER - I HAVE BEEN INFORMED THAT THIS MODIFICATION CAN FLAG UP AS AN ERROR CODE ON AUDI DIAGNOSTICS AND THEREFORE HAS POTENTIAL IMPLICATIONS ON WARRANTY. THERE ARE UNCONFIRMED REPORTS THAT THIS CAN LIMIT ENGINE POWER AD THE ECU CANNOT REGISTER THE SENSOR FOR THE EXHAUST FLAPS WHEN TRYING TO RELEASE/HOLD PRESSURE. THIS MODIFICATION IS TO BE DONE AT YOUR OWN DISCRETION!


This video outlines a tutorial for unplugging and securing disconnected exhaust valves.

It is a common misconception that driving the car in ‘dynamic’ mode causes the exhaust valves to be open all the time. This is in fact ONLY true for driving in 1st gear.

For gear 2 and above in dynamic, the exhaust valves remain closed until approximately 3000rpm, above this the valves will open and the symphony occurs.

Disconnecting these valves manually allows the valves to remain open throughout startup, and throughout the Rev range in all gears, thus allowing greater amplitude of sound during normal driving.

One disadvantage is that this modification WILL cause moderate drone when cruising at low revs in high gear on the motorway.
