Volkswagen says the anti-lock braking system (ABS) and electronic stability control (ESC) in some of its cars are having a fight. When the ABS is activated it can disable the ESC. That's a fight where no-one wins.
"Volkswagen engineers found a fault inside the anti-lock brake system control module that can cause the module to fail whenever the electronic stability control or ABS system activates. A driver will notice warning lights for the brakes, the anti-lock braking system and the electronic stability control system.
Volkswagen says owners who see that light should contact a local dealer immediately.
The affected cars include the 2009 Audi A3.More information on carcomplaints.com
