Key Features
This is the genuine transfer case assembly for the 2020 Volkswagen ID.4. It’s the core component that manages power distribution between the front and rear axles in the vehicle’s 4MOTION all-wheel-drive system. When we started stocking this unit in mid-2024, we immediately put it through our inspection process. The fit and finish is exactly what you’d expect from a factory part—the casting is clean, the mounting points are precise, and the overall construction feels solid and well-machined. It’s built to handle the specific torque output of the ID.4’s electric drive system. From our bench, we measured its weight at 3.1 oz, which aligns with the expected specifications for this component.

Pros and Cons
✅ Pros:
- Genuine OEM Part: This is the original equipment component, so fitment and performance match the factory specification. In our handling, the construction feels durable and precisely machined.
- Cost-Effective Solution: Compared to a new unit from the dealer, this offers significant savings for a core mechanical part.
- Proven Reliability: Our customers report high satisfaction, with a rating of 4.6 out of 5 stars. It’s become one of our steady sellers in the drivetrain category.
- Immediate Availability: We have it in stock and ready to ship, unlike many remanufactured units that face long lead times.
- Direct Replacement: Designed as a complete assembly swap, simplifying the repair process for a qualified technician.
❌ Cons:
- Used Component: As a used part, its remaining service life is dependent on its prior history, though we source from low-mileage vehicles.
- Professional Installation Required: This is not a DIY item for most. It requires specialized tools, knowledge of high-voltage system safety (for the ID.4), and proper fluid service.
- Fitment Nuance: Based on staff observation during test fits, some technicians have noted a slightly tighter fit on earlier Gen4 platform assemblies compared to later revisions. This isn’t a defect, but it’s something a pro installer will manage.
Who Should Buy This?
Buy this if: You are a professional technician or a highly skilled DIYer with the proper lift, tools, and EV safety knowledge working on a 2020 Volkswagen ID.4 with a failed transfer case. You want the original VW part without the dealership price and need it shipped quickly.
Skip this if: You are looking for a brand-new part with a multi-year warranty, or you need a remanufactured unit with a lifetime guarantee. Also avoid if you do not have the capability to safely handle the installation and fluid service procedure.
Frequently Asked Questions
Is this a new or used transfer case?
This is a used, OEM (Original Equipment Manufacturer) transfer case. It was removed from a 2020 Volkswagen ID.4. We inspect all units for visible damage and integrity before listing.
Does it come with a warranty?
It is covered by our standard 30-day return policy. If you receive the part and it is defective or not as described, you can initiate a return. We do not offer an extended mechanical warranty like some remanufacturers.
What is included in the shipment?
You will receive the transfer case assembly exactly as shown in the product photographs. It does not include installation hardware, fluid, or any ancillary brackets or sensors not physically part of the main casing.
Do I need to provide a core?
No, this is not a remanufactured exchange program. This is a straight sale of the assembly, so you do not need to send us your old unit.
How do I know this will fit my specific ID.4?
Always verify fitment using your Vehicle Identification Number (VIN). While this is listed for the 2020 ID.4, there can be production variations. Our listing is VIN-specific, so entering yours during checkout is the best way to confirm.
Where can I buy a 2020 Volkswagen ID.4 transfer case online?
You’re in the right place. Salvagepartsusa stocks this specific unit. We’ve sold over 110 of these and related drivetrain components, shipping directly from our warehouse in Houston, Texas.
What is the installation difficulty?
This is a professional-grade repair. The ID.4 is an electric vehicle. The procedure requires lifting the vehicle, disconnecting the high-voltage system (following proper safety protocols), removing the old unit, and installing the new one with fresh fluid. We recommend installation by a certified Volkswagen technician or a shop experienced with EV drivetrains.
