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.

Does your ABS pump have number 4G0614517AM and control module 4G0907379T?
On offer is a used, working Bosch unit for Audi: pump 4G0 614 517 AM with control module 4G0 907 379 T. Selection is based on the numbers matching your part.
4G0614517AM – Bosch ABS hydraulic unit with module 4G0907379T
This item comprises the valve block, the pump motor and the bolted-on electronic module. VAG number 4G0614517AM is dot-marked in the metal of the block, the motor has a paper sticker, and one of the labels reads ‘ZSB Hydroaggregat ESP9’. The control module has VAG number 4G0 907 379 T and Bosch number 0 265 956 226; an additional number 2 265 106 525 appears on a sticker on the side of the housing, and one of the Bosch numbers is laser-marked on top of the housing.
Five markings to compare
- 4G0614517AM – VAG number of the ABS pump (hydraulic unit), in the metal of the block: 4G0 614 517 AM
- 0265244293 – Bosch number of the hydraulic block (pump): 0 265 244 293
- 4G0907379T – VAG number of the ABS/ESP control module, written: 4G0 907 379 T
- 0265956226 – Bosch number of the control module: 0 265 956 226
- 2265106525 – Bosch number from the sticker on the side of the housing, written: 2 265 106 525 (the label does not describe its role)
The control module with Bosch number 0 265 956 226 also appears in our shop with pumps 4G0614517AK, 4G0614517AJ, 4G0614517AL and 4G0614517AG – it is the same module, but different blocks. That is why the pump number is decisive, and none of the 12 other versions with a different suffix should be treated as a replacement without checking. The ports on the block are labelled with the symbols HZ1, HZ2, VL, VR, HL and HR.
When to suspect the module or the pump
Trouble with the module or pump most often shows up as:
- an illuminated ABS warning light,
- an internal fault logged by the control module,
- no communication with ABS during diagnostics,
- the brake warning light on together with ABS.
Before replacing the unit, rule out cheaper causes: a wheel speed sensor, a fuse, the wiring loom, a connector or low battery voltage – reading the faults with a scan tool will help. After fitting, the control module on many VW Group cars is coded with a scan tool, and on cars with ESP a basic setting of the steering angle sensor and ESP sensors is usually carried out.
Key questions and answers
| Which make is this unit for? |
|---|
| Audi. You establish the fit from numbers 4G0 614 517 AM and 4G0 907 379 T, not by model name. |
| Is the pump in working order? |
| Yes – genuine, used, working. The product features table gives the warranty period. |
| Will version 4G0614517AK or AL fit? |
| Not necessarily. Although the control module may be the same, a different ending on the pump number may mean a different version of the system – choose the AM suffix if that is what your car has. |
| Is bleeding needed after fitting? |
| Yes, bleeding the brake system is a mandatory step after replacing the unit. |
