The faulty part is in the brakes' vacuum servos in some A4, A5,
A6 and A7 sedans, and Q5 and Q7 sports-utility vehicles made
between March and December 2012, a spokesman for the German premium
car maker said.
Oil may enter the vacuum servos of these cars so that drivers
have to press the brake pedal stronger, he said.
