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.

BMW ABS pump 6874019: hydraulic module with control unit
This is a used original ABS pump with a control unit for BMW cars: an aluminium hydraulic block with valves and a pump motor, with the electronics bolted to it. The main number is 6874019, and the other numbers from the labels are listed below. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Numbers to compare
You will find the numbers on the labels, while catalogues list them as a single string:
- 6874019, BMW number in short form, without the group prefix,
- 6874020, BMW number in short form, without the group prefix.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
When an ABS module needs replacing
- the brake pedal pulses or feels uneven for no obvious reason,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
First check the wheel sensors, their wiring and the supply voltage. Only a fault code pointing to the module justifies replacing the pump. After fitting, clear the fault codes and, if necessary, bleed the brake system.
Questions and answers
| Where do I find number 6874019 on my pump? |
|---|
| The numbers are stamped or printed on the aluminium hydraulic block, and the control unit has a separate sticker. Take a close-up photo of both places in good light. |
| Does a lit ABS warning light always mean a faulty pump? |
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| Who makes this module? |
| The module is made by ATE. The manufacturer's name does not change the numbers you should use to match the part. |
| What condition is this ABS module in? |
| It is an original recycled part in good condition, checked by us. Warranty details are in the product features table. |
