Volkswagen AG's (VOW.XE) luxury brand Audi AG (NSU.XE) said Thursday that the latest tests on its diesel engines revealed no irregularities and it passed the results on to the Germany's Motor Vehicle Transport Authority, KBA.

"There were no findings at all after the latest technical analyses, which included the new full-size category comprising the Audi A8, Audi A7 Sportback, Audi A6 and A6 Avant as well as the new Audi Q8," Audi said.

Audi had to recall thousands of cars this spring due to irregularities in the exhaust system, when the KBA was informed. The company has been holding regular meetings with KBA on emissions.

Audi and Volkswagen have been embroiled in an emissions scandal since 2015, when Volkswagen admitted to equipping some diesel models with software that allowed them to sidestep pollution testing. The issue has been extremely costly for Volkswagen and a number of former and present employees have come under investigation in the matter, including Audi's Chief Executive Rupert Stadler.

On Thursday, Audi said internal tests of all its V TDI engines had now concluded.

"Now that the extensive detailed work has been done, the facts are on the table," said Bram Schot, who was named Audi's interim CEO in June following Mr. Stadler's arrest.

The details will be discussed over the coming weeks, the company said. The most recent focus was on current models with third-generation V6 TDI engines.
