The board of scandal-hit Volkswagen meets on Friday to shake up its management.
On the agenda will be choosing a replacement for chief executive Martin Winterkorn, who resigned on Wednesday.
The board may try to find a permanent successor quickly, or it may appoint a temporary chief executive.
It is also expected to dismiss executives tainted by the scandal over the rigging of emissions tests by software in its diesel cars in the US.
In addition, further details on the brands and locations of the 11 million cars involved are due to be set out.
US authorities found that software in a particular diesel engine used by Volkswagen could detect when it was being tested and reduce the emissions produced.
It meant that the emissions in actual driving were considerably higher than those found during testing.
The contenders
Many people's front-runner for the top job is Porsche chief executive Matthias Mueller.
He comes from an engineering background and certainly knows the brands involved, having joined VW-owned Audi in 1977. He was put in charge of all vehicle projects for Volkswagen in 2003.
He is seen as a likely successor because he is popular with the families that control VW. He was already being cited as a likely successor to Mr Winterkorn in April, during the power struggle with then-chairman Ferdinand Piech.
Porsche is owned by Volkswagen, but confusingly, VW itself is controlled by Porsche SE, the holding company, which Mr Mueller is already on the board of.

Another potential successor is Herbert Diess, the current head of the Volkswagen brand.
Mr Diess only joined VW from BMW in July, so will not be tainted by the scandal.
He had a reputation for cost-cutting at BMW, having worked across the group, including a spell at BMW's Mini plant in Oxford.
Given the losses already expected as a result of the emissions scandal, cost-cutting is likely to be a priority.

Elmar Degenhart will not be tainted at all by the scandal
If the board decides to look outside Volkswagen it may consider Elmar Degenhart, chairman and chief executive of the tyremaker Continental.
Being head of a supplier to the car industry means he would be safe even if the investigations sparked by the emissions scandal were to extend to other car companies.
