German Transport Minister Alexander Dobrindt will go to Washington on Monday to discuss the Volkswagen emissions scandal among other topics with his American counterpart Anthony Foxx, German transport ministry sources said.
He will also pay a visit to the United States Environmental Protection Agency.
The company said on Thursday that their tests on EA288 engines, another type of diesel engine that replaced the EA189 engines which cheated the testers, came up clean. The results showed that EA288 engines within the EU are not fitted with the cheating software.
It broke out in September that the German company has engineered a massive program to cheat on pollutant emissions tests conducted by the Environmental Protection Agency.
The German transport ministry has said the company did manipulate European tests too without giving details.
Volkswagen said it may have to refit up to 11 million cars and vans worldwide, and its new CEO Matthias Mueller said recalls would start in January and would be completed by the end of 2016.
The company set aside 6.5 billion euros ($7.3 billion) to prepare for a recall, but it is expected to cost much more.
UBS analysts estimated the total bill for the scandal, including potential fines and lawsuits, could be around 35 billion euros.
International bank Credit Suisse announced earlier this month that it expected the cost to be much higher, claiming the scandal could cost the company 78 billion euros ($87 billion). That figure is 60 percent higher than what BP paid out in the wake of the Deepwater Horizon oil spill.
