I do have a really great alternative brake controller solution for your 2018 Audi Q5 but none of the top brake controller manufactures offers a plug-in brake controller adapter harness like the Curt Custom Wiring Adapter for Trailer Brake Controllers part # C51522 for this vehicle yet. Therefore, you have two options which are to hardwire your own harness in or use a wireless brake controller. If you wish to hardwire your own harness in then you will need to cut the factory plug off the brake controller harness you have now (if present) and then splice into this the Universal Wiring Adapter for Curt Trailer Brake Controllers part # C51515.

I don't recommend the hardwire option for you because it requires splicing into a new vehicle with a very delicate electrical system. Therefore, the best option is a wireless brake controller. The best wireless brake controller on the market right now is the Curt Echo Mobile Trailer Brake Controller part # C51180.

The Echo is a relatively new brake controller that is gaining a lot of popularity. The reason for this is because it does not require any modifications to the tow vehicle, it just plugs into the 7-way and you use your phone to customize settings and activate the manual override. The other major reason as to the growing popularity of this brake controller is because it uses a device you are already comfortable using (your phone), you do not need to read an entire comprehensive manual and familiarize yourself with the controls and codes to use it. Please note that if your phone loses power the brake controller will still function as normal.
