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.

Looking for ABS pump 5N0614109CA for an Audi?
We are selling a used, working TRW unit together with its control module. Go for it when number 5N0 614 109 CA and the TRW numbers on the label correspond to your part.
TRW 5N0614109CA - ABS pump with module, label 54086811E
People usually turn to the complete unit when diagnostics confirm a module or pump failure and the sensors, wiring and power supply have already been checked. This listing covers the set numbered 5N0614109CA, taken from an Audi - the block with valves, the pump motor and the bolted-on control module. Buying the whole assembly, you get components that worked together in one car. The unit label also carries three TRW numbers that help confirm the match.
List of markings on the label
- 5N0614109CA - VAG number of the ABS pump (hydraulic unit): 5N0 614 109 CA
- 54086811E - TRW number from the unit label - 54086811E
- 18898813 - TRW number from the unit label, eight digits: 18898813
- 18898713A - TRW number from the unit label, in the form 18898713-A
There are no legible markings on the pump itself - only faint traces can be seen on the block, and no sticker is visible on the motor. All the numbers for comparison are therefore on the unit label. The shop also offers 10 variants of this pump with a different suffix; this one is distinguished by the CA ending.
Signs of a failing TRW unit
Damage to the unit most often shows up as:
- lost communication between the module and the diagnostic tool,
- the ABS lamp on the dashboard,
- a pump motor fault code.
Before ordering, read the fault codes and assess the condition of the wheel sensors, fuses, wiring loom, connector and battery. Once the unit is fitted, bleed the brakes and then - if the car requires it - code the module and calibrate the ESP sensors.
