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.

8K0614517BT – is this the number on your ABS pump?
If 8K0 614 517 BT is stamped into the aluminium block of your hydraulic unit, this used, working Bosch assembly with module 8K0 907 379 AC is a candidate for fitting to your Audi. Choose it solely on the basis of matching markings.
ABS hydraulic assembly 8K0614517BT with Bosch control module 8K0907379AC
Every wheel has a speed sensor that sends a continuous signal to this unit's control module. The module compares these values, and when one wheel slows down noticeably faster than the others, it treats this as the start of a lock-up. It then operates the valves in block 8K0614517BT, and the pump motor rebuilds the pressure after each cycle. Without correct sensor signals, even a working control module cannot do its job properly.
Numbers to check against your hydraulic unit
- 8K0614517BT – VAG number of the ABS pump (hydraulic unit), stamped into the metal: 8K0 614 517 BT
- 0265236092 – Bosch number of the hydraulic block (pump), on the block: 0 265 236 092
- 8K0907379AC – VAG number of the ABS/ESP control module, on the module label: 8K0 907 379 AC
- 0265950961 – Bosch control module number, written: 0 265 950 961
Both pump numbers are embossed in the aluminium, and in the photos they are largely covered by a watermark – if in doubt, ask us for an additional shot. You can read the module details from the label on its housing, which also bears the wording ‘ESP’; the block ports are marked HZ1, HZ2, VL, VR, HL, HR. The shop has 35 other variants of this pump, so compare the final letters BT as well.
Typical signs of a failed module or pump
Pay attention if you get:
- a message on the scan tool saying there is no connection to the control module,
- the ABS warning light on,
- a stored pump motor fault.
Start the diagnosis with the fault memory, as a damaged wheel sensor, a blown fuse, a corroded plug or low battery voltage can produce the same picture. After fitting, bleed the system and code the module if required; on cars with ESP an ESP sensor calibration is often needed too.
More worth knowing about 8K0614517BT
| Does this unit fit my car? |
|---|
| It comes from an Audi. The model is not the deciding factor – it fits wherever the pump and control module numbers are identical. |
| Is the part used? |
| Yes, it is a genuine component from a dismantled vehicle, in working order. The warranty period is listed in the product features table. |
| How can I make sure before buying? |
| Send us photos of the markings on the block and the module label, or your VIN – we will compare them with this item. |
| Is it enough to compare the Bosch number? |
| Not always. Number 0 265 236 092 identifies only the block, whereas the version of the whole unit for Audi is defined by VAG number 8K0 614 517 BT, so check both. |
Worried about worn digits? Send a photo of the block or your VIN, and we will tell you whether this is the right unit.
