Does anyone have experience of fitting an aftermarket detachable towbar to the 8VA A3 S-Line? I have a 2014 2.0TDi Sportback version. The Westfalia, which I have good experience of, seems to need the replacement Audi lower spoiler & cover panel, all of which puts it beyond my budget.
There is a Witter detachable version with a spec that suggests only a non-visible cut to the bumper lower is needed, which sounds more up my street.
Has anyone tried one and able to comment on it's quality / appearance / ease of fit / use? Or any good alternative?

Any comments / suggestions welcome & appreciated.
