Europe's main stock markets rose at the start of trade on Tuesday, but scandal-hit German automaker Volkswagen suffered a fresh drop.
In opening deals, Frankfurt's benchmark DAX 30 added 0.26 percent to 9,974.13 points.
London's FTSE 100 index was flat at 6,108.87 points and the CAC 40 in Paris slid 0.06 percent to 4,582.92, compared with Monday's close.
Volkswagen stock accelerated losses by more than 4.0 percent.
Shares had plummeted nearly 20 percent Monday as investigations spread into revelations that hundreds of thousands of its diesel cars have software that secretly thwarts US pollution tests.
Volkswagen, the world's largest automaker by sales in the first half of this year, said it had halted all diesel vehicle sales in the United States during a probe into the scandal, which could lead to fines of more than $18 billion (16 billion euros).
