Audi has recalled 127,000 of their luxury cars after authorities suspected they had been fitted with emissions-cheating devices.

The six forced recalls have come long after the company said its internal probe into the devices was over.

They were imposed by the Federal Motor Transport Agency (KBA) the Bild Am Sonntag newspaper reported.

KBA detected 'unacceptable shut-off devices' for all V6 diesel engines with the latest standard Euro 6.

The models concerned are A4, A5, A6, A7, A8, Q5, sq 5, sq 5 Plus and Q 7, totaling 127 000 vehicles in all.

Audi boss Rupert Stadler declared the exhaust gas scandal to be finished last year.

His task force 'Diesel' was to be dissolved in the first quarter of 2018, he announced shortly before Christmas.

He said the inspection of all engines had been completed and further manipulation could be ruled out.

BaS reported that these latest cheating diesels were only produced since the end of 2015 - after the scandal became known.

Audi spokesman Toni Melfi: 'Audi is examining all diesel concepts meticulously for any irregularities.

'In the course of this systematic and detailed review and evaluation, the Federal Motor Transport Agency has now also issued a distinction for Audi models with V6 TDI engines.'

By February 2 at the latest, Audi must present the KBA solutions for all models.

Professor Julius Reiter, a specialist consumer affairs lawyer, said: 'That Audi further damages unsuspecting car buyers shows that the Volkswagen Group does not impress law enforcement authorities or those of the courts.'
