Audi Australia says it has yet to determine precisely how many locally-sold cars, and which models, are equipped with the so-called "defeat device" that allowed Volkswagen Group products to cheat emissions tests, however an announcement is expected soon.
"We don't yet know the full effect of the software on Australian (Audi) vehicles," Audi Australia spokesperson Anna Burgdorf said.
"However, it is our understanding that the software is inactive in all Australian-build Audi vehicles with an EA189 engine."
"We hope to provide that information in the next few days."
The 'Dieselgate' scandal appears to be confined to cars fitted with the Volkswagen Group's EA189 2.0 litre turbo diesel engine, which has been in production since 2009.
The software in question - called a "defeat device" by the US EPA upon its discovery - allowed cars fitted with the engine to pass emissions tests, yet emit up to 40 times the allowed amount of nitrogen oxide during normal driving.
While there's still no clarity on how the issue affects locally-delivered Volkswagens or Skodas, Audi's local offshoot has confirmed that it is working hard to figure out its impact.
It is currently known that 2.1 million Audi models are affected, however roughly two million of those are believed to have been sold in Europe.
Once Audi Australia determines the extent of the EA189 issue, the company pledged it would keep any affected customers informed.
"Our customers are our highest priority at this time and we will be contacting them directly once we have an accurate list of potentially affected vehicles," Burgdorf said.
"We will then confirm our next steps to remove the software from customer's vehicles."
Ms Burgdorf urged any concerned customers to call Audi Australia's customer service hotline: 1300 557 405
