OE 058145703N — Turbocharger for Audi

Wholesale pricing for 058145703N depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

OE 058145703N is the factory reference for this turbocharger on selected Audi models. The Applications table on this page lists the confirmed rows — check trim level and build year against your own fleet before ordering, because one reference can cover several body variants.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the engine & fuel system family — always confirm dimensions and connector layout before you swap.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a turbocharger the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.
