Nick Heidfeld and Adrian Sutil made up over a Bacardi and Coke after colliding during last Sunday's Singapore grand prix.
Heidfeld angrily hit out at his German countryman following the clash, for which Sutil was penalised $20,000 and officially reprimanded by the stewards.
Bild newspaper said they cleared the air at the 'Amber Lounge' after-race party, but 32-year-old Heidfeld nonetheless commented: "Adrian has to learn that things like that don't get him to the finish."
The clash, triggered when Sutil, 26, tried to recover from a spin, put an end to Heidfeld's record-setting run of grand prix finishes.
