MAN probes possible engine fuel use fraud
German engineering group MAN said Wednesday it was investigating claims that fuel consumption readings for its marine diesel engines were falsified to boost sales.
A MAN statement said the firm had "indications of possible irregularities" related to engines made by its Diesel & Turbo division, and that it had alerted public prosecutors to a probe by the group's compliance unit.
Preliminary findings showed "it was possible to externally influence the fuel consumption values for four-stroke marine diesel engines obtained on test stands ... and to display results that deviated from those actually measured."
MAN is checking to see whether the possibility of displaying false consumption values had been used to boost sales and said it would also try to determine "the potential financial consequences."
The engines apparently "gave fuel consumption indications that were lower than than their actual consumption," a MAN spokesman told AFP. "It is not a question of a technical problem but of a deliberate action."
Consumption values are key for clients as they calculate operating costs, he noted.
In 2010, the four-stroke marine diesel engine unit generated around 371 million euros ($523 million) in sales, the company said.
