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.

8K0614517CT – is this the number on your ABS pump?
If your unit has the number 8K0 614 517 CT stamped on it and the control module the marking 8K0 907 379 AM, this listing may be the right one. It is a used, working Bosch assembly from an Audi.
Bosch assembly: block 8K0614517CT and control module 8K0907379AM
This assembly consists of an aluminium hydraulic block with valves, the pump motor and a control module bolted to the block. The block carries Bosch number 0 265 236 191 and the control module 0 265 951 171. The block bears the marking ‘ESP’. On the side of the module you will also find a Bosch sticker with a serial number barcode.
List of the assembly's numbers
- 8K0614517CT – VAG number of the ABS pump (hydraulic unit), stamped into the metal of the block, with the ending CT applied separately: 8K0 614 517 CT
- 0265236191 – Bosch number of the hydraulic block (pump): 0 265 236 191
- 8K0907379AM – VAG number of the ABS/ESP control module: 8K0 907 379 AM
- 0265951171 – Bosch number of the control module: 0 265 951 171
You recognise the hydraulics by the numbers in the block and the port markings HZ1, HZ2, VL, VR, HL and HR. The control module with Bosch number 0 265 951 171 also appears in our listing for pump 8K0614517FK, so tell the two apart by the VAG pump number. In addition, the shop has 35 other versions with different endings.
Symptoms that may suggest a failure
If the assembly is faulty, you will often see:
- no communication with the control module,
- an ABS warning light on the dashboard,
- a pump motor fault stored in the control module.
Before you order the part, check the fault memory with a diagnostic tool and assess the condition of the wheel speed sensors, fuses, wires, the plug and the battery. After fitting the assembly, bleed the brakes; on many VW Group cars the module sometimes needs coding as well.
