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.

How do you match ABS pump 8K0614517BF to your car?
Compare the number stamped in the block of your pump with the reference 8K0 614 517 BF, and the control module label with 8K0 907 379 R. This used, working Bosch assembly from an Audi fits when both markings match.
Bosch 8K0614517BF - ABS unit with control module 8K0907379R
Units with numbers starting 8K0 614 517 come in many variants - in the shop we have 35 versions other than this one. The letters BF at the end distinguish this unit from the rest and may indicate a different version of the system, so getting a single character wrong risks ordering the wrong part. Also compare the Bosch block number 0 265 236 084 and the module marking 8K0 907 379 R with the listing. All three matching is the best confirmation before ordering.
List of pump and module markings
- 8K0614517BF - VAG number of the ABS pump (hydraulic unit), stamped into the metal of the block: 8K0 614 517 BF
- 0265236084 - Bosch number of the hydraulic block (pump), stamped into the metal of the block: 0 265 236 084
- 8K0907379R - VAG number of the ABS/ESP control module, on the control module label: 8K0 907 379 R
- 0265950936 - Bosch number of the control module, on the control module label: 0 265 950 936
You identify the hydraulics by the numbers stamped into the aluminium of the block, next to which there is also the marking ‘ESP’, and the electronics by the stickers on the control module housing, which give 8K0 907 379 R and 0 265 950 936. When comparing, do not skip the letters: BF in the pump number and R in the module number.
How to tell that the pump needs replacing
Typical symptoms are:
- the ABS lamp together with the ESP lamp,
- braking without ABS assistance,
- a pump fault read with a diagnostic tool.
The warning light can also be caused by an ordinary wheel speed sensor, so before the replacement read the faults and check the sensors, fuses, wiring, plug and battery. After fitting this unit, bleeding is essential, and on cars with ESP calibration of the steering angle sensor and the ESP sensors is usually needed too.
