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.

Bosch ABS/ESP unit 8K9614517AF with control module 8K9907379M
Our shop has six more listings with the same base number 8K9 614 517, differing only in the final letter. The letter denotes the version, and a different suffix may mean a different system configuration, so with this unit the full number counts, including ‘AF’. A match on the first digits alone is not enough – the complete set of characters decides. Control module number 8K9907379M comes from the product data, as its VAG label is not visible in the photos.
This unit's numbers and what they mean
- 8K9614517AF – ABS pump (hydraulic unit) – VAG number; on the sticker: 8K9 614 517 AF
- 0265239357 – hydraulic block – Bosch number; on the sticker: 0 265 239 357
- 8K9907379M – ABS/ESP control module – VAG number from the product data, written as 8K9 907 379 M (control module VAG label not visible in the photos)
- 0265952065 – control module – Bosch number; on the sticker: 0 265 952 065
You will find the sticker with the VAG pump number and the Bosch number on the hydraulic block, which is also stamped with ‘ESP’ and the port markings HZ1, HZ2, VL, VR, HL and HR. The Bosch control module number is on the electronic module housing. With so many related versions, check the end of number 8K9 614 517 AF carefully – it is easy to be out by a single letter.
Symptoms that may point to the ABS unit
With a faulty unit, the driver usually notices:
- the ABS warning light on together with the ESP light,
- ABS disabled during braking,
- a pump fault stored in the control module memory.
Before you remove the old part, read the fault codes with a diagnostic tool and inspect the wheel speed sensors, fuses and connector – a sensor alone, or a weak battery, can trigger similar messages. After fitting, the brake system must be bled; on Volkswagen Group cars the control module is usually coded with a diagnostic tool, and with ESP a basic setting of the steering angle sensor is often needed too.
