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.

Are ABS pump 8N0614217 and control module 8N0907379A your numbers?
If your part carries the markings 8N0 614 217 and 8N0 907 379 A, this used, working ATE assembly from an Audi is its equivalent.
ATE hydraulic unit 8N0614217 with module ‘Steuergeraet fuer EDS/Syncro’
The sensors at the wheels pass information on the rotational speed of each wheel to control module 8N0 907 379 A. The module compares these readings, and when one wheel starts to deviate noticeably, it activates the valves and the motor of pump 8N0614217. The same signals allow the electronics to detect a sensor fault - in that case it stores an error and turns on the warning light.
Numbers from the pump and control module stickers
- 8N0614217 - VAG number of the ABS pump (hydraulic unit), on the pump motor sticker: 8N0 614 217
- 10020401474 - ATE number of the hydraulic block (pump): 10.0204-0147.4
- 8N0907379A - VAG number of the ABS/ESP control module, on the label: 8N0 907 379 A
- 10094903763 - ATE number from the control module label: 10.0949-0376.3
You will find the pump number on the silver foil sticker attached to the motor, and the control module details on the label on its housing, which also shows the texts ‘Controller’ and ‘Steuergeraet fuer EDS/Syncro’. The shop has one more version of this pump with a different suffix, so compare number 8N0614217 character by character.
How a failure of this component shows itself
Typical signs are:
- a permanently lit ABS warning light,
- an internal module fault in the fault memory,
- no response from the control module during diagnostics,
- the brake warning light on the instrument cluster.
Before you replace the assembly, read the faults and rule out a damaged wheel speed sensor, a fuse, the wiring loom and plug, and low battery voltage. After fitting, bleed the brakes and - if the car requires it - code the control module with a diagnostic tool.
Questions about assembly 8N0614217
| Which car does the pump fit? |
|---|
| It comes from an Audi; the fit is based on the pump and control module numbers, not on the model. |
| What is the condition and warranty? |
| A used, working, genuine ATE assembly. The warranty period is listed in the product features table. |
| What do the ATE numbers mean? |
| 10.0204-0147.4 is the ATE number of the hydraulic block, and 10.0949-0376.3 is the number from the control module label, typical of an electronic module. |
| Will a pump with a letter at the end of the number fit? |
| Number 8N0 614 217 has no letter suffix here. A pump with a letter may belong to a different version of the system, so such a swap needs to be confirmed first. |
