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 8N0614417?
This used, working ATE hydraulic unit for Audi carries the number 8N0 614 417 with no letter at the end, plus control module 8N0 907 379. Choose it if your part bears exactly these markings.
ATE 8N0614417 - ABS unit with module 8N0907379
The item consists of a hydraulic block with valves, a pump motor protected by a housing and a control module bolted to the block. The motor housing has a paper sticker with the numbers 8N0 614 417 and 10.0204-0148.4. The module label includes the wording ‘Controller’ and ‘Steuergeraet fuer ABS/EDS/MSR/ASR’, which describes the functions it handles.
Markings to compare with your part
- 8N0614417 - VAG number of the ABS pump (hydraulic unit), on the motor sticker: 8N0 614 417
- 10020401484 - ATE number of the hydraulic block (pump), written as: 10.0204-0148.4
- 8N0907379 - VAG number of the ABS/ESP control module, on the label: 8N0 907 379
- 10094903773 - ATE number from the control module label: 10.0949-0377.3
The pump sticker is worn and scratched, but the numbers can still be checked against your part. Note that the VAG number has no letter at the end; our range also includes one variant of this pump with a letter suffix, so do not mix the two up. You can read the control module details from the label on its housing.
When a replacement may be needed
The most common signs are:
- no communication with the ABS module,
- the ABS warning light on the instrument panel,
- a pump motor fault in the fault memory.
Confirm the fault with a scan tool reading, then check the wheel speed sensors, fuses, wiring, connector and battery. Once the hydraulic unit is fitted, bleed the brakes and, if the car requires it, code the control module.
