The next year saw the club in the Regionalliga West , tier II, where their performances over the next few seasons left them well down the league table.
SV Bayer 04 Leverkusen made something of a breakthrough in by winning the division title, but was unable to advance through the playoff round to the first division.
The club was relegated again in , but made a quick return to what was now called the 2. Bundesliga after just one season spent in the third division.
Four years later, the club handily secured a place in the Bundesliga to start to play there in the —80 season. By the mids, SV Bayer 04 Leverkusen had played its way into the upper half of the league table and was well-established there by the end of the decade.
It was during this time, in , that the two-halves of the club that had parted ways over a half century earlier were re-united as TSV Bayer 04 Leverkusen e.
The new club took red and white as its colours. In addition to becoming an established Bundesliga side, the club earned its first honours with a dramatic win in the UEFA Cup.
Down 0—3 to Espanyol after the first leg of the final, Bayer Leverkusen drew even in the return match and then captured the title on penalty kicks, 3—2.

The —08 season was not a successful one for Leverkusen despite a good start to the season; five out of the last ten league matches were lost to clubs in the lower half of the table.
Michael Skibbe was heavily criticised towards the end of the season after he continuously changed his starting line up.
