The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Used ABS pump with control unit, number 0265259849, inspected before sale. Matched by the numbers on the block and sticker.
How to identify ABS pump 0265259849 for your Mercedes
ABS pump 0265259849 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.
Where to find the numbers on an ABS pump
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 0 265 259 849 (catalogue format: 0265259849), hydraulic block manufacturer's number,
- 0 265 956 183 (catalogue format: 0265956183), control unit number,
- A 447 900 88 09 (catalogue format: A4479008809), 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 can point to an ABS pump failure
- valve or pump motor faults are stored in the control unit memory,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS activates for no reason during normal braking,
- the ABS switches itself off shortly after the engine is started.
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
| Are the pump and the control unit sold separately? |
|---|
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| 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 Bosch. 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. |
