Austin confirmed his return in 2013 with the team running under the WIX Filters banner. Austin led early on in the first race of the season at Brands Hatch, he was then passed by Jason Plato and eventually finished third behind Andrew Jordan. He retired from the following two races, in race three he was collected by Dave Newsham who had spun and Austin had a high speed collision with the barriers before coming to a rest in the middle of the track. He took his first pole position in the BTCC at the Knockhill round. He took his first outright win at the next event at Rockingham; he took victory in race two ahead of Gordon Shedden. After that he only scored 11 more points for the rest of the year, finishing 11th in the standings.
