Question:
Hello, Looking to purchase the trailer wiring for my 2014 Q5 TDI. on youtube a gentleman is installing the p/n C56222 wiring for Audi Q5 model year 13 - 17 When I go on your website it can not confirm the fitment for that wiring but tells me to get the p/n C56404 which is $84 instead of the $48 that supposedly works for my car. can you please clarify ? Thank you in advance

Hey Michel, I am not sure how the guy in the video you found was able to install that trailer wiring kit on an Audi Q5 but it was not designed as a fit for your vehicle so it wouldn't work for you and you'd need to go with the part # C56404 instead.
I wonder if he somehow got his part numbers confused or something.
