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.

ABS pump 4G0614517S with control module – does your number match?
We are offering a used, working Bosch ABS unit for Audi: pump 4G0 614 517 S with control module 4G0 907 379 J bolted on. Before you order, check these numbers against the labels on the parts in your car.
Bosch ABS unit 4G0614517S / 4G0907379J for Audi
The electronics on this unit consist of VAG control module 4G0 907 379 J (Bosch 0 265 960 419), bolted directly to block 4G0614517S. The module continuously receives signals from the speed sensors on all the wheels and compares them with one another. When one wheel starts slowing down noticeably faster than the others, the control module opens and closes the relevant valves, and the pump motor rebuilds the pressure in the circuit. This stops the wheel from locking under braking.
Label markings on this assembly
- 4G0614517S – VAG number of the ABS pump (hydraulic unit), on the label: 4G0 614 517 S
- 0265250484 – Bosch number of the hydraulic block, as written on the label: 0 265 250 484
- 4G0907379J – VAG number of the ABS/ESP control module, on the sticker: 4G0 907 379 J
- 0265960419 – Bosch number of the control module, on the label: 0 265 960 419
One label is stuck on the hydraulic block and the other on the control module housing; the block body is also stamped with the port markings HZ1, HZ2, VL, VR, HL and HR. Our shop has another 12 versions with the core number 4G0 614 517, differing in the final letter, so always compare the number together with the S suffix.
When the ABS electronics make themselves known
A fault in the unit or its control module is usually given away by:
- ABS warning light on the instrument cluster,
- internal control module error logged in memory,
- no connection to the control module during diagnosis,
- brake system warning light also on.
First read the fault memory with a diagnostic tool and rule out simpler causes: the wheel speed sensors, fuses, the wiring loom and connector, and the battery voltage. Once the unit is fitted, bleed the brake system. On many VW Group cars the control module also has to be coded, and cars with ESP usually require a basic setting of the steering angle sensor.
Most common questions about this unit
| Which car does this unit fit? |
|---|
| It comes from an Audi. We do not state a specific model – compatibility depends on number 4G0614517S and the control module number, not on the car's name. |
| What condition is the part in, and does it have a warranty? |
| It is a used, genuine part in working order. You will find the length of the warranty in the product features table. |
| Which number is key when matching? |
| First the VAG pump number including the letter S, then the VAG control module number 4G0 907 379 J. |
| What do Bosch numbers 0 265 250 484 and 0 265 960 419 mean? |
| The first identifies the hydraulic block in the Bosch catalogue, the second the control module. They are useful as confirmation, but base your match on the VAG numbers. |
