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.

4E0614517A – does your ABS pump carry this number?
If the block of your pump shows 4E0 614 517 A and the control module is marked 4E0 910 517 A, this used, working Bosch unit from an Audi is a proper candidate for a replacement.
Bosch ABS unit for Audi: pump 4E0614517A, control module 4E0910517A
The whole assembly is run by module 4E0 910 517 A (Bosch 0 265 950 061). The speed sensors at the wheels constantly send it pulses; the control module compares them and, if a wheel is about to lock, opens or closes the valves of block 4E0614517A. A damaged sensor can trigger messages similar to a failure of the module itself, which is why these two components are diagnosed together.
Identification numbers of the pump and control module
- 4E0614517A – VAG number of the ABS pump (hydraulic unit), written 4E0 614 517 A
- 0265225133 – Bosch number of the hydraulic block (pump) – 0 265 225 133
- 4E0910517A – VAG number of the ABS/ESP control module: 4E0 910 517 A
- 0265950061 – Bosch number of the control module, marked 0 265 950 061
The pump markings are stamped into the metal of the hydraulic block – in the photo some of them are covered by a watermark. The block also bears the port symbols HZ1, HZ2, VL, VR, HL and HR. We have two other suffix versions of this pump in the shop, so check that your number also ends in the letter A.
Signs of trouble with the ABS unit
Replacement is most often prompted by:
- the diagnostic tool losing communication with the ABS module,
- the ABS warning light showing while driving,
- a recorded pump motor fault.
Confirm the fault by reading the control module memory and checking the wheel sensors, fuses, wiring, connector and battery. Once the unit is fitted, the brake system needs bleeding, and on an Audi the control module often has to be coded; with ESP, calibration of the steering angle sensor usually follows.
