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.

This used, working ATE unit for Audi has number 4L0 614 517 G on its sticker, along with ATE designation 10.0212-0194.4. Before you order, set both numbers against the ones you can see on your part.
ATE ABS unit 4L0614517G - hydraulic block with control module
The whole unit is usually replaced when diagnostics point to a fault but it is hard to say whether the electronics or the hydraulics are to blame. With this listing you get the hydraulic block with its valves and pump motor, plus the electronic module bolted to it. The module label reads ‘Controller’ and ‘Steuergeraet ESP’ and bears ATE number 10.0926-0319.3. Number 4L0614517G refers to the entire hydraulic unit, and it is the best place to start your comparison.
Markings you will find on this item
- 4L0614517G - VAG number of the ABS pump (hydraulic unit), on the sticker: 4L0 614 517 G
- 10021201944 - ATE number of the hydraulic block, i.e. the pump - written: 10.0212-0194.4
- 10092603193 - ATE number read from the control module label: 10.0926-0319.3
The VAG number and the pump's ATE number are printed on a paper sticker on the pump motor, and number 10.0926-0319.3 on the label of the control module housing. Our shop has 4 other versions of this hydraulic unit with a different suffix, so the letter G at the end of 4L0 614 517 G must match your part.
Signs the control module or pump may be damaged
A faulty ABS unit most often produces these symptoms:
- the ABS warning light on,
- an internal control module fault in the fault memory,
- no communication with the control module during diagnosis,
- the brake system warning light lit.
Before deciding on a replacement, read the faults with a diagnostic tool and inspect the wheel speed sensors, the fuses and the control module connector - a weak battery can create a similar picture too. Once the unit is fitted, the brake system has to be bled, and on many VW Group cars the control module is coded with a diagnostic tool.
Most frequent questions about 4L0614517G
| Which car is this pump intended for? |
|---|
| Audi. We establish compatibility from the numbers on the labels rather than the model name alone - compare the VAG number and both ATE numbers. |
| What condition is the part in, and what about the warranty? |
| It is a used, genuine unit in working order. You can see the warranty period in the product features table. |
| My car has a version with a different letter at the end of the number - will this one fit too? |
| Not necessarily. A different suffix letter may mean a different version of the system, so the safest choice is an item with the identical marking 4L0 614 517 G. |
| Will the brakes have to be bled after the swap? |
| Yes, after the hydraulic block is fitted, the brake system requires bleeding. |
In doubt? Send us a photo of the pump sticker and the control module label, or your VIN, and we will check the fit.
