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 8K0614517AJ with Bosch module – does it match your number?
This is a genuine, used and working unit for Audi: hydraulic block 8K0 614 517 AJ with Bosch control module 0 265 950 604 bolted on. Only buy it once you have compared the markings with your own part.
Bosch ABS block 8K0614517AJ (0 265 235 192) with control module for Audi
You are buying the complete assembly: the valves enclosed in the aluminium block, the electric motor that drives the pump and the control module. VAG number 8K0 614 517 AJ and Bosch number 0 265 235 192 are stamped directly into the metal of the block, and a little further along are the markings of the pipe ports: HZ1, HZ2, VL, VR, HL and HR. On the control module you will find Bosch number 0 265 950 604 and the text ‘ESP’.
Three numbers worth comparing
- 8K0614517AJ – VAG number of the ABS pump (hydraulic unit), stamped in the block: 8K0 614 517 AJ
- 0265235192 – Bosch number of the hydraulic block (pump), in the metal: 0 265 235 192
- 0265950604 – Bosch number of the control module, written: 0 265 950 604
The block digits are not on a sticker – look for them on the aluminium surface, ideally after wiping away dust and grease. You can read the module number from the control module housing. With 35 other variants of this pump with a different suffix in the shop, check that your number ends with exactly the letters AJ.
Symptoms that call for a closer look at the ABS module
The most common include:
- an ABS lamp that is permanently lit,
- an internal module fault in the memory,
- the diagnostic tool unable to connect to the control module,
- the brake warning light on the dashboard.
Start the diagnosis with a scan tool, then inspect the wheel speed sensors, fuses, wiring and control module connector; measure the battery voltage as well, because even a damaged sensor can trigger similar messages. After fitting the unit, bleed the brake system; if the car requires it, the control module is programmed with a diagnostic tool (coding), and with ESP a steering angle sensor calibration is often added.
Before you buy 8K0614517AJ
| Which make is this hydraulic unit for? |
|---|
| Audi. Whether it fits a specific car depends on matching the numbers stamped in the block and given on the control module. |
| Is the assembly in good working order? |
| Yes, it works; it is a genuine part from a dismantled vehicle. The warranty period is given in the product features table. |
| How can I be sure before ordering? |
| Take a photo of the numbers in your pump's block and the control module markings, or send your VIN – we will compare the details and let you know the result. |
| Is comparing just the Bosch number enough? |
| Better not. Number 0 265 235 192 describes the block, but the version is also determined by VAG number 8K0 614 517 AJ with its suffix letters. |
Send us photos of the stamped digits and the module housing, or your vehicle's VIN – we will verify the fit.
