Range comparison

Below, you will find the exact turbocharger models compatible with 1.4 TSI 140 HP engines, each listed with its OEM reference and core deposit details for seamless ordering.

How to choose

Selecting the right turbocharger requires attention to several key factors, from core condition to compatibility with your specific engine variant. These criteria ensure the part will perform as expected in your application.

1. Verify the OEM reference matches your engine’s build code to avoid fitment issues in vehicles like the Golf, Passat, or Octavia.
2. Inspect the core deposit policy to understand return requirements for your used turbo, as most suppliers require a functional core for exchange.
3. Check the variable geometry mechanism for smooth operation, as sticking vanes are a common failure point in 1.4 TSI turbos.
4. Confirm the CHRA (Center Housing Rotating Assembly) is balanced and free of play, which directly impacts boost consistency and longevity.
5. Prioritize turbos with documented remanufacturing processes, including bearing replacement and seal upgrades for extended service life.
6. Assess the packaging for protection during transit, as improper handling can damage the turbo before installation.
7. Compare core prices across suppliers, as some charge premiums for rare variants or high-demand models.

Storage & logistics

For workshops, storing remanufactured turbos requires climate control to prevent moisture damage to the variable geometry components. Bulk orders should be kept in sealed containers with desiccant packs to maintain the integrity of the CHRA and seals. Rotate stock based on expiration dates, as turbos with older cores may have reduced bearing life. Always label inventory with OEM references and model years to streamline picking for technicians. German buyers, in particular, should ensure storage complies with DIN standards for automotive parts to avoid warranty issues.
