I wouldn't have had mine fitted on previous cars if they hadn't been coded, I've had aftermarket bars on my last 2 Audis and 2 BMWs and without the coding you can have annoying warning lights and especially rear parking sensor issues.
I'm not sure but believe that the laws on towbars have been significantly tightened up as well and that it includes fitting by acredited installers but I stand to be corrected on that. My concern would be in the event of an accident or maybe the bikes / trailer detaching and causing damage it might be an excuse for the insurance company to refuse a claim.
On my last 2 Audis I was quoted well over £1000 for towbar and fitting by the dealer, did some research and found they used Westfalia as OEM even at the factory, found a specialist company 30 miles away who fitted the bars in my driveway fully coded for around £600 so your price doesn't look bad.
Hope you enjoy the car, I'm generally very happy with mine.
