A neutral safety switch tells the starting system the selected gear so the engine can only crank in Park or Neutral, an important safety interlock. If a failed switch is the cause of your no-crank-in-Park or, more seriously, an engine that cranks while in gear, this replaces it.
Function: Signals transmission gear position to permit starter engagement only in Park or Neutral.
Direct fit: Designed to install on the listed Audi applications.
Signs it may need replacing: No crank in Park/Neutral, intermittent starting, or cranking in other gears — diagnose the cause before replacing.
