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 4G0614517Q – how can you tell it is the right part?
Set the number from your pump's block against 4G0 614 517 Q and against control module number 4G0 907 379 G. We are offering this used, working Bosch unit from an Audi, and compatibility is determined by the numbers, not by appearance alone.
Bosch ABS unit 4G0614517Q with module 4G0907379G for Audi
The base number 4G0 614 517 appears in our shop in 12 other versions that differ only in the final suffix. A different letter may mean a different version of the system, so comparing just the start of the number gives no certainty. With this pump, the full number 4G0614517Q is what counts, supplemented by the Bosch numbers: 0 265 250 448 for the block and 0 265 960 403 for the control module. Only when the whole set of numbers matches can this item be considered the right one.
Full set of markings to compare with your part
- 4G0614517Q – VAG number of the ABS pump (hydraulic unit), stamped into the metal of the block: 4G0 614 517 Q
- 0265250448 – Bosch number of the hydraulic block (pump), written: 0 265 250 448
- 4G0907379G – VAG number of the ABS/ESP control module, on the label: 4G0 907 379 G
- 0265960403 – Bosch number of the control module, on the label: 0 265 960 403
Here the pump number is not printed on a sticker but stamped directly into the metal of the hydraulic block; next to it are the port markings HZ1, HZ2, VL, VR, HL and HR. You can read the control module numbers from the label on its housing. Compare character by character, paying particular attention to the final Q.
When to suspect the ABS unit
A failure of the block or control module may be indicated by:
- ABS and ESP/ASR switched off together,
- a stored valve fault code,
- an ABS warning light coming on just after the engine starts.
Start with a scan-tool diagnosis, then check the wheel speed sensors, fuses, wiring with connector and battery voltage – a broken sensor often gives a very similar picture. After replacement the brakes must be bled; on many VW Group cars the control module is coded with a diagnostic tool, and with ESP a basic setting of the steering angle sensor is usually carried out.
Most common questions about this pump
| Which car is this unit intended for? |
|---|
| Audi. We do not name a specific model – compatibility is established from the VAG numbers of the pump and control module. |
| What condition is the part in, and what is the warranty? |
| It is a genuine, used part in working order. The warranty period is shown in the product features table. |
| Does the system have to be bled after fitting? |
| Yes. Replacing the hydraulic block requires the whole brake system to be bled, otherwise the brakes will not work properly. |
| Which number should I look at first? |
| At 4G0614517Q on the block, and then at 4G0 907 379 G on the control module. The Bosch numbers serve as additional confirmation. |
