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.

Mercedes ABS pump: numbers 0265290521 and 0265956378
ABS pump 0265290521 for Mercedes is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number 0265290521 and related numbers
The numbers from the listing, as written on the labels and as a single string:
- 0 265 290 521 (catalogue format: 0265290521), hydraulic block manufacturer's number,
- 0 265 956 378 (catalogue format: 0265956378), control unit number,
- A 906 900 48 04 (catalogue format: A9069004804), Mercedes 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 ABS problems can point to
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- the ABS activates for no reason during normal braking,
- the ABS warning light comes on together with the stability control warning light.
Before buying a module, read the fault codes with a diagnostic tester. A faulty wheel speed sensor or its wiring can cause the same symptoms, and in that case replacing the pump will not help. After replacement the fault codes usually need to be cleared, and if the brake lines have been disconnected, the system must be bled.
Questions and answers
| What is the difference between numbers 0265290521 and 0265956378? |

| Where do I find number 0265290521 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. |

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