Consult the manual as all depends on MY...
My 986 it varied... could be 6sec, 2min, 24min or even 60min as I recall. Mid 9x6 they changed a bit I think and then again with 9x7... and again on the 9x7.2 with intro of DFI. Now, many of the newest Porsches require motor at operating temperature, vehicle on a level surface. engine running for 2min.
Wonder what the requirements will be in the Taycan
