Remanufactured 0AU Transfer Case Assembly 0AU409053T For VW Tiguan 5N Passat CC 4Motion Audi Q3 8U Quattro 1.8T 2.0T 4WD AWD differential drive transfer gearbox

1.Product Overview

This is remanufactured 0AU 4‑wheel‑drive transfer case for VAG MQB/PL48 platform 4‑motion / Quattro vehicles. This unit distributes torque between front and rear axles. Every unit is fully stripped, cleaned, worn internal components replaced, reassembled and run‑on test bench to eliminate common factory faults such as shudder on acceleration, 4WD error codes, grinding noise under turning. It is a direct replacement part for failed original transfer case, suitable for vehicle repair at local auto repair shops.

2.Fitment & Parameter Table

3.Inspection & Testing Standard

After full disassembly, all housing is hot‑washed & shot‑blasting cleaning. We inspect housing for crack, deformation, thread damage. Replace all worn friction clutch plates, bearings, oil seals, piston seals. After reassembly, every finished 0AU transfer case goes on dedicated hydraulic test bench, simulating forward/reverse, low‑speed cornering, high‑speed running. Monitor oil pressure, noise level, check for oil leakage. All test data will be logged for quality traceability; defective units will be rejected before packing.

4.Core Competitive Advantages

All critical wearing spare parts are replaced with new high‑quality spare parts instead of re‑using old used parts. Complete bench testing before shipment reduces on‑vehicle failure risk. Our remanufactured 0AU transfer case is a cost‑effective alternative to expensive brand‑new OEM unit. The housing is carefully inspected for hidden cracks to avoid sudden breakdown after installation. Suitable for direct repair work without extra modification.

5.Professional Installation Guidance

Before installation, technicians must drain and replace the dedicated transfer‑case gear oil (special VAG transfer case fluid, NOT regular ATF). Inspect the connecting flange and driveshaft for bending or damage. After mechanical fitting, clear existing 4WD fault codes with professional VAG diagnostic scanner, perform basic adaptation & calibration for the all‑wheel‑drive system. Road test the vehicle for shudder or abnormal noise. Improper fluid type or missing adaptation will trigger 4WD malfunction warning.

6.Packaging & Transportation

Each remanufactured 0AU transfer case is wrapped with anti‑rust plastic film, padded with thick shock‑absorbing foam inside sturdy export wooden crate with IPPC fumigation mark. We fill a small amount of anti‑rust preservation oil inside the gear chamber for sea shipping long‑term transit. Heavy‑weight cargo will be shipped by sea freight or LCL; air freight is available upon client request. Mark part number and VAG model information outside crate for easy stock management.

7.Factory Strength Introduction

Our remanufacturing workshop specializes in VAG series transfer cases and automatic transmission components. We own dedicated disassembly stations, cleaning tanks and hydraulic test‑benches for transfer‑case testing. Our QC team inspects every finished unit strictly following remanufacturing workflow. We serve numerous overseas repair garages and auto spare‑parts wholesalers, providing remanufactured driveline spare parts with stable quality and competitive lead‑time.

8.FAQ

Q1: What preventive measures do you take against micro‑cracks on the transmission housing during remanufacturing of A6MF1‑2WD? A1: Before reassembling the A6MF1‑2WD transmission, our technicians perform comprehensive visual inspection and magnetic particle testing for every used housing to hunt for invisible micro‑cracks. Once cracks are detected, the housing will be scrapped directly instead of being welded for repair. We never adopt risky welding repair on housing. After cleaning, each housing will go through thread checking and thread repair for damaged holes. Strict housing screening helps us reduce early failure complaints for our B‑level wholesale clients and their downstream repair shops, creating stable quality for bulk export orders.

Q2: Can you provide independent test reports for each A6MF1‑2WD unit instead of only batch certification?

A2: We cannot issue an official third‑party independent test report for every single transmission unit. Nevertheless, every finished A6MF1‑2WD must complete our in‑house dynamometer bench test before shipment. We record shifting pressure data for each gear, lock‑up performance and leakage status during testing. We can supply the internal factory test record copy for each unit upon your formal request. These recorded documents can assist your local repair shops for internal archive and help you handle after‑sales communication with end customers.

Q3: If we place mixed container orders with multiple transmission models, how will you manage batch‑specific documentation for A6MF1‑2WD?

A3: When you arrange mixed container shipments including A6MF1‑2WD and other transmission models, our documentation team will separate packing list data according to product model individually. Each model will have its own quantity, gross weight, net weight and dimension information clearly listed on documents. The commercial invoice can be generated either as a consolidated single invoice or separated invoices as your requirement. We double‑check model descriptions to avoid confusion during import customs clearance at your destination port and reduce customs‑holding risks for your wholesale business.
