Croatia striker Ivica Olic's late goal denied Cardiff a win over Wolfsburg in their last pre-season friendly.
Goals from Marcel Schafer and Kevin De Bruyne put the German team 2-0 up inside 27 minutes.
Cardiff levelled by half-time with a Peter Whittingham free kick and Nicky Maynard's shot after a Fabio pull-back.
Kim Bo Kyung tapped-in after Kenwyne Jones's header hit a post to put them ahead, but Olic's clever flick made it 3-3.
Kim later had to leave the field with an ankle injury, a concern for manager Ole Gunnar Solskjaer with Cardiff starting their Championship campaign at Blackburn on Friday, 8 August.
