Used Volkswagen ID.4 Transfer Box

Only the all-wheel-drive (AWD) versions of the ID.4 have a transfer box — these are the dual-motor variants badged as ID.4 GTX or the twin-motor AWD models, which use a second electric motor on the front axle alongside the rear-drive unit, with a power transfer unit distributing drive. The rear-wheel-drive single-motor ID.4 has no transfer box at all, so if your car is the standard RWD version you will not find this part on your vehicle. Check your V5 or run a VIN check to confirm whether your ID.4 is a single-motor RWD or dual-motor AWD before searching.

The ID.4 was launched in the UK in 2021 and received a facelift for the 2024 model year, so a 2021 and a 2023 car both sit within the pre-facelift generation and share the same fundamental AWD drivetrain architecture. However, whether the transfer unit itself interchanges directly between those years — accounting for any mid-production revisions to mountings or software — is something you should confirm with the breaker against your exact registration before buying. Supplying your motor code from the V5 or a VIN check gives the breaker the most reliable basis for matching the part.

Trim level itself does not determine transfer box fitment — what matters is the drivetrain configuration, specifically whether the car is the dual-motor AWD setup and which motor codes are fitted. The GTX badge denotes the performance AWD variant, but if a non-GTX ID.4 was also supplied in AWD form with the same motor codes, the transfer unit may be shared. Confirm the motor code from your V5 or VIN check and give that to the breaker, rather than relying on the trim name alone.

No — the single-motor rear-wheel-drive ID.4 does not have a transfer box at all, so there is no such part to take from one. The transfer box is unique to the dual-motor AWD variants, which use it to distribute power to the front axle via a separate front motor and power transfer unit. You will need to source the part specifically from a breaker dismantling an AWD or GTX ID.4.

This is a question you must raise directly with the breaker and your fitting workshop rather than assuming the part is simply a mechanical swap. Electric vehicle drivetrain components can involve ECU communication and software calibration, and whether the transfer unit requires coding to your vehicle's systems is not something that can be stated as fact here. A specialist EV-familiar workshop or VW dealer should confirm the requirements for your specific registration before you commit to a purchase.

The 2024 facelift marks a genuine generation boundary for the ID.4, and whether the transfer box crosses that boundary is not something that can be confirmed without checking the specific motor codes on both donor and recipient vehicles. Name that boundary to your breaker, provide your motor code from the V5 or a VIN check, and ask them to verify compatibility against the exact part from the dismantled car. Do not assume pre- and post-facelift units are interchangeable without that confirmation.
