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.

Which markings on the label of ABS pump 1K0614517CN really matter?
The key ones are VAG number 1K0 614 517 CN and module number 1K0 907 379 BD. This used, working ATE unit fits an Audi or Volkswagen with a part bearing identical markings.
1K0614517CN and 1K0907379BD - ATE ABS unit for Audi and VW
Two numbering systems meet on this item. The numbers starting with 1K0 were assigned by the VAG Group: the 614 group refers to the ABS hydraulic unit (here 1K0614517CN), and 907 379 to the control module (1K0 907 379 BD). The numbers in the format 10.0212-… and 10.0961-… come from ATE: the first describes the hydraulic block, the second is on the control module label. When buying, go by the VAG numbers and use the ATE numbers to confirm the version.
Number by number - what they mean
- 1K0614517CN - VAG number of the ABS pump (hydraulic unit), printed on the label as 1K0 614 517 CN
- 10021206504 - ATE number of the hydraulic block (pump) - 10.0212-0650.4
- 1K0907379BD - VAG number of the ABS/ESP control module, module label: 1K0 907 379 BD
- 10096103423 - ATE number from the control module label, written 10.0961-0342.3
The printed barcode label on the pump motor cover carries the hydraulic unit numbers; on the module you will find the words ‘Controller’ and ‘Steuergeraet ESP’ together with the control module numbers. As the shop holds 21 other suffix versions of this pump, pay attention to the CN ending.
When to suspect a faulty unit
Damage is usually indicated by situations like these:
- ABS and ESP/ASR stop working at the same time,
- the control module reports a valve fault,
- the ABS warning light is on after the engine starts.
Before removal, read the fault memory and rule out problems with the wheel sensors, fuses, wiring, connector and battery. After replacing the unit, the brake system must be bled; on Audi and Volkswagen cars the control module often needs coding too, and with ESP a basic setting of the steering angle sensor is usually added.
