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.

BMW 5 ABS pump: numbers 3451678544203 and 0265250507
ABS pump 3451678544203 for BMW 5 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. According to the listing, the pump comes from the BMW 5 model.
Numbers to compare
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 3451 6785442 03 (catalogue format: 3451678544203), BMW number of the ABS pump (hydraulic part),
- 0 265 250 507 (catalogue format: 0265250507), hydraulic block manufacturer's number,
- 0 265 960 428 (catalogue format: 0265960428), 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.
When an ABS module needs replacing
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- 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.
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.
