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.

ABS pump 1K0614517CA - how can you be sure it is the right part?
We are selling a genuine, used and working ATE unit removed from an Audi: hydraulic unit 1K0 614 517 CA together with control module 1K0 907 379 AS. What decides the fit is matching numbers, not the model name.
ATE 1K0614517CA and control module 1K0907379AS - ABS unit for Audi
With this unit it is easy to make a mistake: our shop has as many as 21 other versions that differ only in the suffix at the end of the number. The letters CA in 1K0614517CA are not decoration - a different suffix may mean a different version of the system. So compare the whole string of characters, and the control module number 1K0 907 379 AS as well. The ATE numbers on the stickers will help clear up any remaining doubt.
What the stickers say
- 1K0614517CA - VAG number of the ABS pump (hydraulic unit), on the sticker: 1K0 614 517 CA
- 10021205604 - ATE number of the hydraulic block (pump), written as 10.0212-0560.4
- 1K0907379AS - VAG number of the ABS/ESP control module, on the label: 1K0 907 379 AS
- 10096103353 - ATE number from the control module label: 10.0961-0335.3
- 28561052223 - a further ATE number from the control module label: 28.5610-5222.3
On this item the pump numbers are not stamped into the metal - you will find them on a paper sticker attached to the pump motor. The control module label reads ‘Controller’ and ‘Steuergeraet ESP’ and carries three numbers: one VAG and two ATE. When comparing, pay attention to every character, because with 21 related versions the difference can come down to a single letter.
Symptoms that may point to this component
A problem with the ABS pump or control module is usually indicated by:
- ABS and ESP/ASR switching off at the same time,
- a fault code for one of the valves in the control module memory,
- a warning light that does not go out after the engine starts.
Start the diagnosis by reading the fault codes, because similar symptoms can be caused by a damaged wheel sensor, a fuse, a wire, a connector or a weak battery. Once the unit is fitted, bleed the system and code the control module if required; on cars with ESP a basic setting of the steering angle sensor is usually carried out as well.
Key points before you buy
| Which car does this unit come from? |
|---|
| From an Audi. We do not give the model, because the part is selected by number 1K0614517CA and control module number 1K0 907 379 AS. |
| Am I buying a working part with a warranty? |
| Yes, it is a genuine used item in working order. We have listed the warranty period in the product features table. |
| Will the control module need coding? |
| Quite possibly - on many VW Group cars the ABS/ESP control module is coded with a diagnostic tool after replacement. |
| Do the brakes have to be bled? |
| Yes. Removing the hydraulic block lets air into the system, so it must be bled after fitting. |
