Genuine OEM (Original Equipment Manufacturer) parts are built to Volkswagen's exact standards. They fit perfectly, perform as designed, and carry the quality assurance your vehicle was engineered with.

Why it matters: your Volkswagen was precisely calibrated with specific parts. Genuine OEM replacements maintain that calibration-fuel economy, performance, safety, and longevity all stay as Volkswagen intended. Aftermarket parts *might* work, but they're not guaranteed to deliver the same fit or durability.

Our Parts Department at Castle Volkswagen of Schaumburg stocks genuine Volkswagen components and can order what we don't have in stock quickly. We also carry accessories and upgrades if you want to personalize your ride.

Trusting genuine parts means trusting your investment. **Call (847) 593-4700** to ask about specific parts, or visit us at **1000 E Golf Rd, Schaumburg, IL 60173** to browse our inventory.
