Curt Echo Bluetooth Trailer Brake Controller C51180 Installation for 2015 Audi Q7 TDI


Does the 2015 Audi Q7 TDI with the factory tow package require and additional brake controller for towing a trailer with electric brake as if so what is the correct brake controller that works with this car?


Expert Reply:

Yes, you will need an aftermarket trailer brake controller to equip your Audi Q7 for towing a trailer with brakes. The actual components included in an OEM "tow package" will vary by brand and model but the trailer brake controller itself is not included among them.

If your Q7 has a factory 7-way connector similar to the one shown in the linked photo you have the option for an exceptionally easy brake controller installation.

Curt's Echo Trailer Brake Controller # C51180 requires NO wiring, cutting, splicing or any other parts for installation, apart from your existing smartphone which serves as the display and control device. Plug the Echo into your 7-way, plug the trailer into the Echo, pair it to your smartphone and you're DONE! If you don't have a 7-way you'll add # ETBC7L.

The Echo offers you the same smooth proportional trailer braking as hardwired types like the excellent P3 # 90195 but without the hassle of disturbing the sensitive wiring systems in a premium vehicle like the Q7. Plus, it can be installed in any other vehicle with a 7-way, should the need arise. Please check out the linked videos to see this unique product in action.
