The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Need ABS unit 0265250451 with control module 4G0907379F?
This used, working Bosch assembly from an Audi combines hydraulic block 0 265 250 451 with VAG control module 4G0 907 379 F. Choose it by the block and module numbers, checking them against the markings in your own car.
Bosch block 0265250451 with control module 4G0907379F (0265960404) for Audi
The heart of the electronics here is VAG module 4G0 907 379 F, listed in the Bosch catalogue as 0 265 960 404. It continuously gathers pulses from the speed sensor on each wheel and uses them to detect the moment one of the wheels starts to lock. It then actuates the valves in block 0265250451, and the pump motor restores the fluid pressure in the circuit. If the signal from any sensor is faulty, the system usually switches ABS off and indicates this with a warning light.
Block and control module numbers
- 0265250451 – Bosch number of the hydraulic block (pump), written 0 265 250 451 – taken from the product data
- 4G0907379F – VAG number of the ABS/ESP control module, on the label: 4G0 907 379 F
- 0265960404 – Bosch number of the control module, on the label: 0 265 960 404
The hydraulic block markings are stamped directly into the metal, but on this item they are shallow and dirty, so we do not give the pump's VAG number, and Bosch number 0265250451 comes from the product data. The label on the control module housing remains legible – its numbers 4G0 907 379 F and 0 265 960 404 are the ones to compare with your part. The block also shows the port markings HZ1, HZ2, VL, VR, HL and HR.
Signs that the ABS electronics are failing
When the control module or the whole unit develops a fault, you will most often see:
- an ABS warning light that stays on,
- a stored internal module fault,
- the control module not responding to diagnostic tool requests,
- the brake system warning light also lit.
Before you remove the old unit, run a diagnosis with a scan tool and check whether the culprit is actually a wheel sensor, a blown fuse, a damaged wiring loom, a connector or low battery voltage. After replacement the brakes must be bled; on VW Group cars the control module often needs coding, and with ESP the steering angle sensor and ESP sensors are usually calibrated.
Buyers' questions
| Which car is this hydraulic unit meant for? |
|---|
| The part comes from an Audi. We do not state the model – compatibility is confirmed by control module number 4G0 907 379 F and Bosch block number 0 265 250 451. |
| What condition is the unit in, and where can I find the warranty? |
| We are offering a genuine used part in working order. The warranty period is given in the product features table. |
| Will a control module with a different letter instead of F work too? |
| Not always. A different final letter in the VAG number may indicate a different version of the system, so the safest option is to look for an identical part number. |
| Is bleeding necessary after fitting? |
| Yes – once the brake lines are connected, the whole system must be bled. |
Not sure? Send us a photo of the label on your control module or your VIN, and we will check compatibility.
