How to distinguish an original from a fake: 5 key signs

Spare parts market for ŠKODA is flooded with counterfeit goods, especially for body parts. Fake bumpers often have distorted geometry, which leads to installation problems and shortens their service life. Here's how to recognize the original:

1. Marking. On the inside of the original bumper there are:
   • 📌 Logo ŠKODA or VW Group.
   • 📌 Article number (for example, 1Z6 807 407 C).
   • 📌 Production date (format YY.WW, where YY - year, WW - week).

Quality of plastic. The original is made from polypropylene (PP) with additives for frost resistance. Counterfeits are often made from cheap ABS plastic, which cracks at −10°C.

Wall thickness. The original has a plastic thickness in critical areas (for example, near fasteners) of at least 3.5 mm. For fakes this figure rarely exceeds 2.5 mm.

Mounting holes. In the original, they have a clear geometry and are reinforced with metal inserts. In fakes, the holes often “float” and there are no inserts.

Packaging. Original parts are supplied in original boxes ŠKODA with hologram and certificate.

🔍 Useful lifehack: Before purchasing, ask the seller to take a photo of the inside of the bumper with the markings. Compare the font and placement of the inscriptions with reference photos (they can be found on the forums Skoda-Club.ru or Drive2).
