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 8R0614517J with control module – is this your number?
Check whether 8R0 614 517 J is stamped on the block of your pump and the module sticker reads 8R0 907 379 C. If both markings match, you are looking at an equivalent of your part: a used, working Bosch unit taken from an Audi.
Hydraulic unit 8R0614517J with electronics 8R0907379C (Bosch)
A complete assembly is usually the choice when the failure affects both the hydraulic section and the electronic module, or when the diagnosis cannot pin down the culprit. The listing includes the hydraulic block fitted with valves, the motor of pump 8R0614517J and control module 8R0 907 379 C mounted on the block. The hydraulics and the electronics both carry original Bosch markings: 0 265 236 123 for the block and 0 265 950 984 for the module. So there is no need to hunt separately for electronics that match the hydraulics.
Factory markings to check
- 8R0614517J – VAG number of the ABS pump (hydraulic unit), stamped into the metal of the block: 8R0 614 517 J
- 0265236123 – Bosch number of the hydraulic block (pump), stamped into the metal of the block: 0 265 236 123
- 8R0907379C – VAG number of the ABS/ESP control module, on the module sticker: 8R0 907 379 C
- 0265950984 – Bosch number of the control module, on the module sticker: 0 265 950 984
Both pump numbers are stamped directly into the aluminium of the hydraulic block, while the control module has its own sticker on the housing. Our shop has many other versions of this unit with a different suffix letter, so compare the whole number 8R0614517J with the listing, not just the first part of it.
When this unit may be faulty
During diagnostics and on the road, you may come across:
- an illuminated ABS warning light,
- an internal control module fault code,
- a diagnostic tool that cannot see the ABS module,
- the brake system warning light on.
Start with the fault memory, then inspect the wheel sensors, wiring loom, plug and fuses, and finally measure the battery voltage – a weak battery also generates false codes. Once the assembly is in place, it is time to bleed the brakes and, on many VW Group cars, to code the module and calibrate the ESP sensors as well.
FAQ: ABS unit 8R0614517J
| Which car does this part come from? |
|---|
| From an Audi. We do not specify the model here – the part is matched by the numbers 8R0 614 517 J and 8R0 907 379 C. |
| What about condition and warranty? |
| The assembly is used, genuine and in working order. You will find the warranty period in the product features table. |
| My pump is numbered 8R0 614 517 with a different suffix – is that a problem? |
| It may be. The letter after the number identifies the version, and a different version of the system is not always interchangeable. The safest choice is a part with the same suffix as the one you have now. |
| Do the brakes have to be bled after fitting? |
| Yes, the installation cannot be completed without bleeding. With this pump, also plan for coding the control module with a diagnostic tool. |
