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.

0265255815 – is this the number on your ABS pump?
If your unit shows 0 265 255 815, this used, working Bosch assembly from an Audi could be the right replacement. It comes with control module 8W0 907 379 J – compare both numbers to confirm compatibility.
Bosch hydraulic unit 0265255815 with module 8W0907379J for Audi
The listing covers the complete assembly: the aluminium hydraulic block with its valves, the pump motor and the electronic module bolted to the block. The Bosch number 0 265 255 815 is laser-marked on the top surface of the module housing, and the markings also include the text ‘ZSB Hydroaggregat ESP9’. The control module carries its own numbers: the VAG Group number 8W0 907 379 J and the manufacturer's number 0 265 956 241. A white sticker with a 2D code is attached to the pump motor.
Markings read from this particular unit
- 0265255815 – Bosch number of the hydraulic block (pump) – the main number of this pump, shown on the housing as 0 265 255 815
- 8W0907379J – VAG number of the ABS/ESP control module, on the label: 8W0 907 379 J
- 0265956241 – Bosch number of the control module, written as 0 265 956 241
- 2265106528 – Bosch number from the sticker on the side of the housing: 2 265 106 528 – the label does not say what it refers to
The engraving on the aluminium block is faint and mostly illegible, so the laser-marked number on the housing and the control module label are what you should compare first. Module 0 265 956 241 is also listed in our shop with pump 8W0614517H, so the control module number alone does not settle the choice – what counts is a match on block number 0265255815.
When the ABS unit needs attention
A fault in this component usually gives itself away through:
- no communication with the control module during diagnostics,
- an ABS warning light that stays on,
- a stored pump motor fault code.
First connect a diagnostic tool and read the fault memory, then inspect the wheel speed sensors, fuses, wiring and connector, and the battery – some of these produce exactly the same symptoms. Once the unit is fitted, bleed the brakes; on many VW Group cars the control module also has to be coded, and with ESP a basic setting of the steering angle sensor is usually carried out.
