Roughly 2.1 million Audi models worldwide are involved in the on-going Volkswagen emissions scandal, with the company revealing to newswire service Reuters that the controversial EA189 engine was fitted to numerous model lines.
Audi, which is part of the Volkswagen Group, equipped the A1, A3, A4, A5, A6, Q3, Q5 and TT with the 2.0 litre EA189 turbo diesel four-cylinder, which was recently discovered to be fitted with an emissions test cheating device.
After the scandal broke, the Volkswagen Group indicated up to 11 million cars worldwide may be equpped with the so-called "defeat device".
Audi's 2.1 million affected cars are part of that 11 million total, however other brands within the Volkswagen Group are expected to be exposed to the controversy as well.
Czech brand Skoda is one of them, though the models embroiled in the EA189 scandal - since dubbed "dieselgate" - have yet to be confirmed. Seat, Volkswagen's Spanish sub-brand, has yet to confirm its involvement.
With the dieselgate fiasco confined to the EA189 engine, the majority of Volkswagen's current products (which have since transitioned to the Euro 6 compliant EA288 engine) are unaffected.
It has yet to be announced which VW Group models sold locally are affected, or how many.
