Left Side Door Wing Mirror Glass Heated for VW Golf 5 MKV 2003-2008

Restore clear visibility and safe driving with this heated left side wing mirror glass designed specifically for Volkswagen Golf Mk5 models from 2003 to 2008. Engineered as a direct replacement for Original Equipment reference 3C0 857 521, this component utilizes a dual-view surface configuration that pairs a standard main mirror with a convex side section, broadening your field of vision while maintaining accurate distance perception. The built-in heating technology draws power through your existing circuitry to dissolve frost, thaw ice, and repel water droplets rapidly, keeping your peripheral sight effective in harsh weather conditions.

Benefits & Tips

• Dual-Surface Clarity: Combine the stability of a flat standard mirror with the wide-angle advantages of convex coverage, minimizing blind spots alongside the driver's door.
• Active De-fogging: Engage the rear climate zone button linked to the wing mirrors to activate the internal resistive traces, removing condensation instantly without waiting for natural airflow.
• Dimensional Fit Check: Confirm the replacement space measures 168 mm across by 110 mm high before purchase; ensure the attachment tabs align with your current glass mounting points for a secure fit.
