To activate the electrical brakes found on large boat trailers, horse trailers, and travel trailers, a brake controller is required.
The Curt TriFlex™ proportion-based brake controller is an electronic control module that activates a trailer’s electronic braking system in proportion to the tow vehicle’s brake engagement. The TriFlex™ brake controller contains an accelerometer that automatically adjusts the brake output when going up or down a hill and is compatible with antilock brakes and cruise control.
On vehicles equipped with a towing package, The TriFlex™ brake controller plugs into Audi’s four-wire electrical harness located under the lower-left dash.
Please observe all Audi towing capacity ratings and guidelines before use. See Owner's Manual for details.
