Last year's Monaco race winner Da Costa posted his time in the final eight minutes of the second practice session, following a red flag called for Mahindra's Alexander Sims as he pulled over at the entry of the Rascasse with a broken front-right steering arm.
Sims appeared to have an incident with Nissan e.dams' Sebastien Buemi, which was placed under investigation by the stewards - but was not deemed worthy of any further action.
