A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Does ABS pump 8K0614517BK fit your Audi?
It fits if 8K0 614 517 BK is stamped on the block of your pump and the module is marked 8K0 907 379 T. We are offering a used, working Bosch assembly, matched by these numbers being identical.
8K0614517BK with electronics 8K0907379T - Bosch ABS hydraulics
During hard braking, module 8K0 907 379 T constantly monitors the signals from the wheel speed sensors. When a wheel starts to lock, the electronics switch the valves in the hydraulic block and briefly lower the pressure in the circuit of the locking wheel. The motor of pump 8K0614517BK returns the fluid to the system, so the braking force comes back quickly. In this way the wheel regains grip and the car remains steerable.
Numbers to compare with your part
- 8K0614517BK - VAG number of the ABS pump (hydraulic unit), stamped into the metal of the block: 8K0 614 517 BK
- 0265236075 - Bosch number of the hydraulic block (pump), stamped into the metal of the block: 0 265 236 075
- 8K0907379T - VAG number of the ABS/ESP control module, on the module sticker: 8K0 907 379 T
- 0265950933 - Bosch number of the control module, on the module sticker: 0 265 950 933
Both hydraulic numbers are stamped into the metal of the block, next to the port markings HZ1, HZ2, VL, VR, HL and HR; you will find the module details - 8K0 907 379 T and 0 265 950 933 - on its sticker. Because the shop has as many as 35 other variants of this unit with a different suffix, compare the number in full, including the letters BK.
When the ABS assembly stops working properly
The fault is given away above all by:
- ABS and ESP warning lights on at the same time,
- ABS not working during braking,
- a pump fault stored in the control module.
Start the diagnosis by reading the faults with a diagnostic tool, then check the wheel speed sensors, fuses, wiring, plug and the condition of the battery - a damaged sensor produces very similar symptoms. After the replacement, bleed the system; on cars with ESP, the steering angle sensor is usually calibrated as well.
