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.

Which markings matter on the label of ABS pump 8R0614517DN?
Above all, VAG number 8R0 614 517 DN on the block and number 8R0 907 379 BF on the control module – these are exactly the markings this used, working Bosch unit for Audi carries.
Bosch 8R0614517DN: ABS pump, block 0265239567, control module 8R0907379BF
The numbers on this unit come from two sources. The car manufacturer gave the pump the designation 8R0 614 517 DN and the module 8R0 907 379 BF; the letters at the end indicate the specific version. Bosch, as the maker of the unit, uses its own numbering: 0 265 239 567 for the hydraulic block and 0 265 952 301 for the control module. In practice the VAG numbers decide the selection, and the Bosch numbers serve as confirmation.
Markings from the block and control module
- 8R0614517DN – ABS pump (hydraulic unit) – VAG number, in the metal of the block: 8R0 614 517 DN
- 0265239567 – hydraulic block – Bosch number, in the metal of the block: 0 265 239 567
- 8R0907379BF – ABS/ESP control module – VAG number from the label: 8R0 907 379 BF
- 0265952301 – control module – Bosch number from the label: 0 265 952 301
In practice, the ‘label’ means two places: the markings engraved in the metal of the hydraulic block and the sticker reading ‘ESP’ on the control module housing. The block also shows the port symbols HZ1, HZ2, VL, VR, HL, HR. We have 12 other variants with the base 8R0 614 517, so the letters DN must match.
When the ABS unit is due for replacement
Typical symptoms include:
- ABS and ESP/ASR switched off by the control module,
- a hydraulic valve fault code,
- the ABS light showing right after the engine starts.
Before you replace the unit, use a scan tool to check the fault codes and the condition of the wheel speed sensors, wiring, fuses and battery. Once this item is fitted, bleeding will be necessary, and usually control module coding and a basic setting of the ESP sensors as well.
