German Federal Motor authority censored the 'dieselgate' reports of domestic carmakers

Now Dobrindt is attempting to use Porsche as a sacrifice pawn to avoid being associated with the emissions cartel," Krischer said.The Ministry of Transport did not deny that it had "discussed technical questions" with producers for the "report of the Volkswagen investigatory commission". Such a procedure was "internationally commonplace and necessary", the ministry insisted.Monday's revelations are the most recent episode of a long-running scandal in which Dobrindt's ministry has been criticised for excessively close ties with German carmakers.In December 2016, it was shown that the "Volkswagen investigatory commission" had removed sensitive passages from a report into diesel vehicle emissions.
