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.

How can you tell whether ABS pump 8K0614517CJ suits your car?

ABS pump 8K0614517CJ and control module 8K0907379AH – Bosch, Audi
Under sudden braking, a wheel can start to lock – the control module detects this from the abrupt drop in its speed. It then opens and closes the valves in block 8K0614517CJ, reducing the pressure at that wheel, and once the wheel is turning again the pump motor restores the pressure needed for braking. The cycle repeats many times, so the car remains steerable. On this item the block has Bosch number 0 265 236 104, and the module 0 265 950 964.
VAG and Bosch numbers of this unit
- 8K0614517CJ – VAG number of the ABS pump (hydraulic unit), stamped in the block: 8K0 614 517 CJ
- 0265236104 – Bosch number of the hydraulic block (pump), stamped in the metal: 0 265 236 104
- 8K0907379AH – VAG number of the ABS/ESP control module, written: 8K0 907 379 AH

The pump numbers are stamped into the aluminium block, by the port markings HZ1, HZ2, VL, VR, HL, HR, while the control module numbers appear on its housing marked ‘ESP’. We also list the same control module, 8K0 907 379 AH (Bosch 0 265 950 964), with pump 8K0 614 517 CL – so it is the block number, not the module number, that decides the choice.
What to look out for with an ABS fault
The unit may have been damaged if you see:
- the ABS and ESP lights lit at the same time,
- ABS not working during braking,
- a pump fault stored in the memory.
Diagnostic tool and fault list first, then a check of the sensors at the wheels, fuses, wiring loom and battery. If everything points to the unit itself, bleed the system after fitting it; the control module may need coding, and with ESP a basic setting of the steering angle sensor is usually carried out at the end.
