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.

Searching for ABS unit 8E0614517AT with control module 0 265 950 468?
Here is a used, working Bosch hydraulic unit removed from an Audi: 8E0 614 517 AT and 0 265 234 330 are stamped into the aluminium, while the electronic module is marked 0 265 950 468. You can judge compatibility by these three numbers.
Bosch 0 265 234 330 with module 0 265 950 468 – ABS pump 8E0614517AT
The electronics of this unit constantly compare the pulses coming from the sensors at each of the four wheels. When one of them brakes more sharply than the rest, module 0 265 950 468 recognises an impending lock-up and uses the valves in block 8E0614517AT to correct the pressure in that wheel's circuit. If a sensor signal is faulty or drops out, the control module disables the function and switches on the warning light.
Factory and manufacturer markings
- 8E0614517AT – VAG number of the ABS pump (hydraulic unit), stamped into the aluminium block: 8E0 614 517 AT
- 0265234330 – Bosch number of the hydraulic block (pump), stamped into the metal: 0 265 234 330
- 0265950468 – Bosch control module number, on the module label: 0 265 950 468
Don't look for a sticker on the Bosch housing – both hydraulic numbers are stamped into the metal, right next to the symbols HZ1, HZ2, VL, VR, HL, HR. The control module housing has a label with the number 0 265 950 468 and the marking ‘ESP’. As we have 8 different versions of this pump on our shelves, compare the full 8E0 614 517 AT with yours, letters included.
How a control module or pump failure shows up
A fault in this unit most often looks like this:
- the ABS light coming on while driving,
- an internal electronics fault code,
- the scan tool not seeing the control module,
- the brake warning light on the instrument cluster.
Before settling on 8E0614517AT, start by reading the codes, then check the wheel sensors, wiring, control module plug, fuses and battery. Once fitted, the unit requires the brakes to be bled; with an ESP system the steering wheel position sensor is then usually calibrated, and the module quite often needs coding.
Buyers' questions about 8E0 614 517 AT
| Which make was this unit fitted to? |
|---|
| Audi cars. We do not give the model – you can check the fit using the hydraulic and electronic markings. |
| What condition and warranty does this item have? |
| A used original from a dismantled vehicle, in full working order. The warranty period is shown in the product features table. |
| What do Bosch numbers 0 265 234 330 and 0 265 950 468 mean? |
| The first, beginning 0 265 2…, identifies the hydraulic block; the second – from the 0 265 9… series – the electronics. They are manufacturer's designations that supplement the VAG number. |
| Will an 8E0 614 517 version with a different ending fit? |
| It might, but not necessarily – a different suffix is often a sign of another version of the system. It is safer to choose identical letters AT. |
Send us a picture of the module label and the digits on the housing – we will happily check whether the versions are the same.
