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.

What should you look for on the label of ABS pump 4G0614517AG?
Above all, VAG number 4G0 614 517 AG and control module number 4G0 907 379 Q – those are the markings on this used, working Bosch unit from an Audi. If yours are identical, that is a good sign the part fits.
4G0614517AG – Bosch ABS unit with control module 4G0907379Q, Audi
This item carries two kinds of number. Strings beginning with 4G0 are VAG markings: 4G0 614 517 AG identifies the hydraulic unit with pump, and 4G0 907 379 Q the ABS/ESP control module. Bosch numbers 0 265 243 289 and 0 265 956 226, on the other hand, are the manufacturer's catalogue designations for the block and the electronic module. The label also shows the text ‘ZSB Hydroaggregat ESP9’.
VAG and Bosch numbers of this unit
- 4G0614517AG – VAG number of the ABS pump (hydraulic unit), written: 4G0 614 517 AG
- 0265243289 – Bosch number of the hydraulic block (pump), written: 0 265 243 289
- 4G0907379Q – VAG number of the ABS/ESP control module, written: 4G0 907 379 Q
- 0265956226 – Bosch number of the control module, written: 0 265 956 226
The pump markings appear in three places here: a laser-marked number on top of the plastic housing, the VAG number stamped into the metal of the block, and a paper sticker on the motor. Control module 4G0 907 379 Q is also listed in our shop with pump 4G0614517AJ, and Bosch module 0 265 956 226 with versions AK, AM, AJ and AL. In total we have 12 other suffixes, so the control module number alone is not enough to choose the part.
When the unit may need replacing
Damage to this part is often signalled by:
- ABS and ESP/ASR switched off at once,
- a hydraulic valve fault stored in the control module,
- a warning light coming on just after the car starts.
It makes sense to begin diagnostics with a scan tool and a check of the components that give similar symptoms: wheel sensors, fuses, wiring, the connector and the battery. After fitting, bleed the system; on VW Group cars the control module is usually coded with a diagnostic tool, and with ESP a basic setting of the sensors is normally performed.
Questions and answers
| Will the unit fit my car? |
|---|
| It comes from an Audi. You can confirm compatibility by comparing number 4G0614517AG and the control module number – the car model is not the deciding factor here. |
| What condition is the part in? |
| Used, genuine, working. We have put the warranty period in the product features table. |
| Do the brakes need bleeding after replacement? |
| Yes, once the block is connected the brake system must be bled. |
| Which number matters most? |
| The pump's VAG number, including the suffix AG. Because the same control module appears with several pump versions, treat its number as supplementary. |
Take a photo of the sticker on the pump motor and the control module label, send them with your VIN, and we will compare the markings.
