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.

Is ABS pump 3451678783601 the right part for your BMW?
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 3451678783601, 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
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 3451 6787836 01 (catalogue format: 3451678783601), BMW number of the ABS pump (hydraulic part),
- 6787837, BMW number in short form, without the group prefix,
- 10.0960-0841.3 (catalogue format: 10096008413), control unit number.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
What can point to an ABS pump failure
- the ABS warning light comes on after the engine is started and stays on,
- the ABS warning light comes on together with the stability control warning light,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.

|---|
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |

| 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 pump in? |
| It is a used original part, inspected before sale. You will find the warranty period in the product features table. |
