[17] He contested five of the remaining eight rounds with Edenbridge Racing, finishing second at Silverstone and scoring third at Spa-Francorchamps after another pole position; this left him seventh in the standings.
[25] In 1999, Kristensen returned to the Super Tourenwagen Cup and improved his results, winning two races at the Nürburgring and one at Hockenheim to finish third in the standings, narrowly ahead of teammate Tarquini.
[32] During the campaign, Kristensen claimed two pole positions and won four races alongside Rinaldo Capello, but missed out on the title following a crash at the season finale caused by a delaminated tyre.
The pair almost won at Mid-Ohio thanks to a fuel-saving strategy, but Kristensen, having driven without pitting for over one-and-a-half hours, ran out of fuel coming towards the finish line and coasted home in second.
[38][39] A truncated 2003 campaign followed, in which Kristensen claimed a commanding victory in the rain at Spa and triumphed at the 1000 km of Le Mans held on the Bugatti Circuit, both alongside Seiji Ara.
[40][41] Kristensen also continued his Le Mans success story that year, claiming pole and winning for Team Bentley with Capello and Guy Smith.
[47][48] A strong opening season, where Kristensen claimed podiums at the Lausitzring, Spa, and Brno — which saw him complete an Audi 1-2 behind Mattias Ekström — helped the Dane to ascend towards the front of the standings.
[52][53][54] Though he fell out of the title hunt due to a lack of wins, Kristensen, who made his final rostrum appearance at the second Lausitzring round, finished third in the championship.
[57] The momentum from this win carried forward into his third DTM season, as two runner-up finishes at Hockenheim and the Lausitzring preceded a victory from pole at Oschersleben, which put Kristensen into the lead of the championship.
[61] However, a non-score at the next race in Barcelona proved to be a setback, and despite two third places in the final two rounds Kristensen dropped to third in the standings, in what turned out to be his most successful DTM season.
[67] Once he returned, the Dane achieved a best finish of fifth at the Norisring and claimed a sole pole position at the final Hockenheim round; this resulted in 14th place in the standings by year's end.
[72] In what he announced to be his final campaign in the DTM, Kristensen finished eighth overall again, having inherited a victory at the season opener in Hockenheim after a puncture for leader Ekström.
[74] With his focus on endurance racing from 2010, Kristensen and Audi entered two rounds of the Le Mans Series that year, finishing third at Spa after losing second place late on to Stéphane Sarrazin.
[75] In a chaotic Le Mans that included early contact caused by the BMW of Andy Priaulx, Kristensen, Capello, and McNish finished third in an Audi 1-2-3.
[102] Thanks to a late fire for the leading, factory-entered Porsche 911 GT1 allowed Kristensen and his teammates to win the race, one lap ahead of the second-placed car.
[103] Kristensen drove for BMW the two following years, but retired early in 1998 before experiencing drama in 1999, where the team led going into the final hours but a heavy crash for teammate JJ Lehto caused by a stuck throttle put them out of the event.
[42][108] He and Smith drove out an authoritative lead during the race's halfway point and, together with Capello, finished two laps ahead of the second-placed sister car.
[117] The 2006 race saw Kristensen finishing in third place in the new diesel-powered Audi R10, with a change of the car's fuel injectors in the first hours and further problems dropping him and teammates Allan McNish and Capello out of contention early.
[119] His Audi crew took the lead during the night and remained there until hour 17, when the car lost its left rear wheel and crashed out, with Capello driving.
[120][121] Returning in 2008, Kristensen played a huge part in beating Peugeot by gaining up to seven seconds on Jacques Villeneuve during rainy stints in the night, before taking the lead on strategy in the morning.
[124][125] Another third in 2010 following a crash from Kristensen caused by a GT car was followed by an early retirement in 2011, when teammate McNish suffered a harrowing accident from which he emerged unscathed.
[91] The final Le Mans appearance for Kristensen came a year later included a run in the lead on Sunday but also its loss due to a turbocharger replacement; he, Duval, and Lucas di Grassi finished second behind the #2 Audi.
