A Seat fitted towbar will come with full manufacturers approval and the electrics will be fully integrated into the existing electronic systems.All towbars have to be CE approved ,whoever makes them,however ,an aftermarket towbar will not have the same level of electronic complexity.So you may find the rear park sensors (if fitted) are not disabled when a trailer is hooked up and also there will be no additional trailer warning on the dash,only a buzzer at the rear of the car.I am sure there are thousands of cars out there with non dealer fit towbars that work perfectly ok.So its make your mind up time.

You'll probablly need the manufacturers' "Plug and play" connections on a new car like that, plus a dealer ECU adjustment /reset. It's not as easy as just tapping in to the lighting circuits these days. There are relays and bypass kits available for many newish models but it depends on the car as to whether you can go that route. A reputable fitter should use the OEM kit and charge a lot less than that, I would have thought. I fitted one myself a couple of months ago, to an 08 Octavia, it's not too bad a job , two evenings worth. I was able to go with the bypass kit/relay, so the whole job cost me £90.

See elecie's answer--- more comprehensive than mine!!
