Application & Compatibility

This unit is listed as a replacement application for Audi A3 TDI vehicles equipped with AHF or ALH 110HP engines. Buyers should verify the engine code and production year against their specific vehicle to ensure correct matching. The turbocharger references OEM numbers 454232-3, 454232-5003, and 454232-5003S for identification purposes. Always cross-check these reference numbers with your existing unit or service documentation before ordering. Confirm that the physical dimensions and port configurations match your requirements to avoid installation issues.

Technical Notes

The GT1749V and GT1749MV models often feature variable-geometry turbine housings to manage exhaust gas flow efficiently. Typical configuration may include VNT design and oil-cooled system (verify per application). Buyers should inspect the actuator arm position and wastegate related hardware for proper operation before installation. Ensure all mounting flanges are clean and free of debris to maintain seal integrity. Verify that the compressor and turbine wheels rotate freely without binding or excessive play. Check oil feed and return lines for blockages to prevent bearing failure during initial startup.
