<s>[INST] The next text is a question of a member of the European parliament:"Written Question E-6115/2009 on ‘Liquid fuel pricing’ raised doubts about the reliability of fuel pricing methods and the uncontrolled and counterproductive nature of those methods, with particular reference to the role of companies ‘active in and providing services to’ the crude oil sectors.  Even though it did not recognise the problems raised at that time, the Commission subsequently (2013) carried out an investigation into suspected collusion and rigging in fuel pricing, which was the subject of questions E-005997/2013 and E-002227/2015.  In both cases, the Commission replied that the investigation had not yet been completed and it was therefore unable, at that stage, to say to what extent consumers had been affected by the infringements concerned.  In the light of the above, and given that eight years have now passed since the first question was tabled and five years have passed since the first inspections were carried out, can the Commission provide updated information on this process? What are the conclusions of the investigation, to what extent were consumers affected (how many millions of euro too much did European consumers have to pay for petrol and diesel), and what steps have been taken following the conclusion of the investigation?"
