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 4L0614517K to your car?
The simplest way is by number: this used, working ATE hydraulic unit 4L0 614 517 K with its control module fits an Audi that has a unit with the same markings installed.
4L0614517K - ATE ABS pump for Audi with control module
The markings on this item come from two sources. 4L0614517K is the VAG Group number given to the pump - it is the number used to order the part for an Audi. The remaining numbers were assigned by ATE: 10.0212-0303.4 describes the hydraulic block, while 10.0926-0326.3 and 10.0619-3104.1 were read from the module label. The final letter K in the VAG number denotes the version, so it is crucial when comparing.
Schedule of markings
- 4L0614517K - VAG number of the ABS pump (hydraulic unit), on the sticker: 4L0 614 517 K
- 10021203034 - ATE number of the hydraulic block (pump), written 10.0212-0303.4
- 10092603263 - ATE number from the control module label: 10.0926-0326.3
- 10061931041 - second ATE number from the control module label, in the form 10.0619-3104.1
The sticker with the pump numbers is on the motor housing, and the control module label is on the module itself, reading ‘Controller’ and ‘Steuergeraet ESP’. As the shop offers 4 other versions of this pump with a different suffix, compare the number with your own part before placing your order.
Signs of trouble with the ABS unit
Drivers most often notice:
- the ABS warning light together with the ESP light,
- ABS failing to intervene when braking,
- a pump fault logged in the control module.
The first step should be reading the fault codes with a scan tool and checking the wheel speed sensors, fuses, wiring and plug - as well as the battery, whose low voltage can mislead a technician. After replacement, the brakes need bleeding, on many VW Group cars the module needs coding, and on cars with ESP the ESP and steering angle sensors usually need calibrating.
