By the mid-20s the club was playing in the highest level local league, the Bezirksliga Baden, but had descended to lower level play by the early 30s. They recovered themselves to return to high level district league play by the end of the decade and in 1935 sent defender Hermann Gramlich (3 caps) to the national side.
Following World War II all organizations in the country, including football and sports associations, were ordered dissolved by occupying Allied authorities. Most were quickly re-established, including the Villingen side which was re-formed as ASV Villingen before once again assuming its traditional identity in 1949. In 1951 FC Villingen was promoted to the Amateurliga Südbaden (II) where they immediately took the division title. The club continued to play well and repeated as champions in 1955, after which they slipped to become a mid-table side.
After the 1959–60 season the club became part of the newly formed Amateurliga Schwarzwald-Bodensee (III) where they played until elevated to the second division Regionalliga Süd after a title win in 1966. They earned mid-table results there until being relegated in 1972 carrying with them a heavy debt burden that hobbled the club for years. They captured Amateurliga Schwarzwald-Bodensee (III) championships in 1973 and 1974 before moving over to the Amateurliga Südbaden, in what was now fourth tier football after league re-organization in the country, where they won their third title in four years in 1976. Through the 70s the team enjoyed success in regional cup play taking the Südbadischer Pokal in 1974, 1976, and 1979.
After another shuffle of German football leagues, 08 was placed in the newly formed Amateur Oberliga Baden-Württemberg (III) where they played for a couple of seasons before descending to the Verbandsliga Südbaden (IV) in 1980. They twice clawed their way back up on the strength of Verbandsliga titles in 1983 and 1985 before settling into fourth tier play until the mid-90s. A second place finish in 1994 kept the club in fourth division play in the Oberliga Baden-Württemberg for a single season, after which they were relegated to the now fifth division Verbandliga Südbaden. Since the turn of the millennium the club has played as an "elevator side" moving up and down between the Verbandsliga and Oberliga. Villingen currently plays in the Oberliga Baden-Württemberg (IV) after being promoted following their latest Verbandsliga title in 2006.
