Used DQ381 0GC Transmission Oil Pump OE 0GC325577E 0GC325577G for Audi DSG Dual Clutch Gearbox

This electronic auxiliary oil pump matches Audi models equipped with DQ381 (0GC) wet dual clutch DSG transmission, corresponding OE codes 0GC325577E / 0GC325577G. The auxiliary pump supplies stable hydraulic pressure for the transmission cooling and lubrication system during idle, low-speed and stop-start operation. It solves common faults including insufficient oil supply, overheating, start-stop failure, transmission warning light and power limitation caused by failed original auxiliary pump. Every unit undergoes professional electrical and pressure testing before delivery for direct replacement.

1. Visual inspection: Check pump housing for cracks, deformation and connector damage.
2. Internal impeller inspection: Verify no wear, jamming or foreign object damage.
3. Electrical test: Check motor conductivity, operating current and response performance.
4. Hydraulic pressure test: Simulate working condition to confirm stable oil output.
5. Sealing inspection: Ensure no internal leakage during continuous operation.

• Pre-shipment Full Function Testing

Each auxiliary pump passes electrical and hydraulic testing to reduce failure risks after installation.

• Direct OEM Replacement

Identical mounting holes, plug interface and installation size, no modification required during assembly.

• Complete Supporting Parts Supply

We supply DQ381 valve bodies, clutch assemblies, overhaul kits and solenoids, supporting mixed consolidated orders.

• Flexible Wholesale Policy

1 piece minimum trial order. Tiered discount for bulk orders. Neutral unbranded packaging. Negotiable warranty terms for long-term overseas wholesale partners.

1. Clean the transmission oil pan and replace the DSG transmission filter synchronously during installation.
2. Check wiring harness connector for corrosion and ensure tight locking to avoid poor contact.
3. Fill with correct specification DSG transmission fluid after assembly.
4. Clear fault codes and perform basic transmission adaptation with professional diagnostic equipment.
5. Complete road test to confirm no overheating, no fault codes and normal start-stop function.

Q1: Can 0GC325577E and 0GC325577G pumps be swapped directly? Is programming required after installation?

A1: They can be mechanically interchanged on DQ381 0GC gearboxes with identical mounting structure and plug interface. No compulsory ECU reprogramming is needed after replacement. But we still recommend clearing stored transmission fault codes and finishing basic road adaptation. Improper adaptation may trigger occasional temperature alarms or start-stop function faults. Confirm the original OE number before purchase to avoid unnecessary maintenance risks for local repair shops.

Q2: Only gearbox model DQ381 is offered, without VIN or photos of the original pump. Can you confirm the matching pump accurately?

A2: We cannot guarantee perfect matching relying merely on DQ381. Although most DQ381 gearboxes adopt this auxiliary pump, different production batches have subtle hardware differences. Without VIN or original part pictures, mismatching risks exist. You’d better ask your customer to supply the OE number or clear photos of the old pump to confirm compatibility and avoid overhaul losses for local repair garages.

Q3: What inner buffer protection do you use? Will continuous shaking and extrusion during ocean shipping damage the housing or plastic plug?

A3: Each auxiliary oil pump is wrapped with thick shockproof foam, then placed into independent neutral cartons. The packaging effectively absorbs impact and vibration during long sea transportation. Proper packaging greatly lowers risks of shell deformation and plug fracture. Nevertheless, violent external impact may still cause damage. We record packing videos before shipment as evidence to handle disputes once cargo damage occurs.
