Restore the punchy performance and efficiency of your 1.4 TSI engine with this brand-new premium replacement turbocharger. Engineered for the single-turbocharged version of the EA111 engine family, this unit is a precision-manufactured "Plug & Play" solution designed to withstand the high exhaust temperatures of modern downsized petrol engines.

Detailed Vehicle Compatibility & Power Output

This turbocharger is a direct 1:1 replacement for the following models equipped with the 1.4 TSI / TFSI (1390 ccm) engine:

Technical Specifications & Cross-Reference

This unit replaces the Mitsubishi TD025 / TD02 series. Verify compatibility using the following identification numbers:

Key Product Features

• 100% Brand New: Zero-mileage assembly. Unlike remanufactured units, every part—from the turbine housing to the high-speed internal bearings—is factory-new.
• VSR High-Speed Balancing: Every core is balanced at speeds exceeding 150,000 RPM to eliminate vibration and ensure silent operation and a long service life.
• Pre-Calibrated Wastegate: The internal wastegate actuator is factory-set to ensure exact boost delivery for 122/125 PS power curves, protecting your engine from overboost.
• Thermal Durability: Manufactured with high-nickel content alloys to resist the cracking often seen in original turbine housings due to high exhaust gas temperatures.

Critical Installation Requirements

To ensure the longevity of your new turbocharger on the 1.4 TSI engine:

1. Mandatory Oil Service: Perform a full oil and filter change. Use only high-quality synthetic oil meeting VW 504.00 / 507.00 specifications.
2. Turbo Priming: Fill the oil inlet port with clean engine oil and manually rotate the compressor wheel multiple times before the first start to ensure the bearings are lubricated.
3. Inspect Oil Feed Line: Check the oil supply pipe for carbon deposits or "coking." On the 1.4 TSI, oil starvation is a common cause of turbo failure; replacing this line is highly recommended.
4. Cooling System: This turbocharger is water-cooled. Ensure the coolant level is correct and the system is properly bled to prevent localized overheating.
