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 5N0614109BL to your car?
Start with VAG number 5N0 614 109 BL, then check the label: numbers 17618898 and 17618998A and the markings HW: H07 and SW: 0151. This is a used, working TRW assembly from an Audi.
TRW 5N0614109BL - ABS unit with label 17618898 / 17618998A
With this assembly, the full number is more important than its beginning. The same start, 5N0 614 109, is shared by different versions of the unit, and the letters at the end decide the match - here BL. Besides the VAG number, the TRW label carries two additional numbers, 17618898 and 17618998A, with no described role, and the markings GNO, HW: H07 and SW: 0151. All of these entries should agree with your part.
Numbers to compare with your own pump
- 5N0614109BL - VAG number of the ABS pump (hydraulic unit): 5N0 614 109 BL
- 17618898 - number from the TRW label: 17618898
- 17618998A - number from the TRW label: 17618998A
On the label, look for the two TRW numbers, the marking GNO, and the markings HW: H07 and SW: 0151. Begin the comparison with the letters BL in the VAG number, because these are what most often distinguish neighbouring versions. If even one entry differs from yours, ask us to verify it.
How does a unit fault show itself?
A damaged assembly is usually given away by:
- the ABS and ESP warning lights on at the same time,
- ABS switched off during braking,
- a pump fault in the fault memory.
Before buying, read the fault codes and rule out the wheel sensors, fuses, wires, the plug and a weak battery. After fitting, bleed the system, and on cars with ESP usually calibrate the steering angle sensor and the ESP sensors.
