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 4F0614517K – how do you check it is the right part?
Compare number 4F0 614 517 K and control module marking 4F0 910 517 K with those in your car. This Bosch unit, removed from an Audi, works properly although it is used – and only matching numbers decide the fit.
4F0614517K and 4F0910517K – Bosch ABS unit marked ‘ESP’
This part carries four numbers with different roles. The markings 4F0614517K and 4F0910517K were assigned by the VAG Group – the first describes the hydraulic unit, the second the ABS/ESP control module. Bosch, as the manufacturer, added its own numbers: 0 265 234 260 for the block and 0 265 950 429 for the module. When ordering a part for an Audi, go by the VAG markings; the Bosch ones serve to confirm the version.
Four numbers to compare
- 4F0614517K – VAG number of the ABS pump (hydraulic unit), written: 4F0 614 517 K
- 0265234260 – Bosch number of the hydraulic block (pump) – marking 0 265 234 260 stamped in the block
- 4F0910517K – VAG number of the ABS/ESP control module, marked 4F0 910 517 K
- 0265950429 – Bosch number of the control module, read from the label as 0 265 950 429
The pump markings are stamped into the aluminium block, and a white paper sticker with the VAG numbers has also been applied to the body; in the photos some of the stamped characters are covered by a watermark. The control module label bears the text ‘ESP’. As the shop has 8 variants with a different suffix, make sure the final letter K is the same as on your part.
When the Bosch unit starts to fail
Typical signs of a damaged ABS unit are:
- ABS and ESP/ASR inactive while driving,
- a hydraulic valve fault code in the module,
- an ABS warning light that stays on after the key is turned.
Start the diagnosis with a scan tool, because similar messages are also generated by a damaged wheel sensor, a blown fuse, a partly torn wire or a drained battery. Once the block is fitted, the brakes have to be bled, control module 4F0 910 517 K generally coded with a diagnostic tool and, with ESP, the steering angle sensor usually calibrated.
