VW Bulb Failure Warning Light

The VW bulb failure warning light is a common issue that many Volkswagen owners face. This warning light typically illuminates on the dashboard when the vehicle's computer system detects a problem with one or more of the exterior lights. However, sometimes this warning can persist even after replacing faulty bulbs, causing frustration for drivers.

Causes of Persistent Warning Light

There are several reasons why the bulb failure warning light might remain on after replacing bulbs:

  • Faulty wiring or connections
  • Corroded sockets or terminals
  • Incompatible aftermarket bulbs
  • Sensor malfunction
