Description
Robotic transmission control unit MM_BVMP_MCP_CEM0 for CITROEN C4 cars
!!!!!!!! Attention, it cannot be used on C4 PICASSO or C4 GRAND PICASSO !!!!!!!!
I can also buy the 2529X2 gearbox from us
Tested – fully functional
The robotic gearbox ECU for Citroën C4 cars is a specialized control unit of the MM_BVMP_MCP_CEM0 system, intended exclusively for the robotic gearbox of these models. Thanks to the original codes and clear identification, it is the ideal solution in the case of gear failure, emergency transmission mode or error messages related to automated gear shifting.
Manufacturer: PSA – Citroën / Peugeot
Model: Citroën C4 (not C4 Picasso, not C4 Grand Picasso)
Product codes: 9663876280, 2529WR, 2531A0
Other numbers: MM_BVMP_MCP_CEM0, possibility of use with bundle 2529X2
This robotic gearbox control unit is from the original production of PSA Citroën / Peugeot and is intended for Citroën C4 cars with a robotic gearbox, where it controls the actuators, the clutch and the shifting process itself. A faulty or malfunctioning transmission ECU is typically manifested by jerking when starting, loss of some gears, spontaneous switching to N, emergency mode or illumination of the transmission warning light on the instrument panel.
Important notice: this unit is not intended for C4 Picasso or C4 Grand Picasso models and is not suitable for use in these cars. When searching by part number, it is therefore crucial to respect the specified model designation.
The part is intended primarily for professional auto mechanics and experienced home repairers who work with PSA robotic transmissions. The unit is fully functional, suitable as a replacement for a defective unit and represents a cost-effective solution compared to a new unit from an authorized service center.
Installation recommendations:
– Before removing the old ECU, disconnect the battery and wait a few minutes for the system to discharge.
– Check the condition of the connectors and wiring, especially the contacts at the connection point of the transmission harness (e.g. 2529X2).
– During assembly, make sure that the contacts are clean and that all connectors are firmly clicked, so that there is no intermittent contact.
– After the physical replacement of the ECU, it is advisable to carry out diagnostics, basic settings / adaptation of the robotic transmission (learning extreme positions, calibration of the clutch and shifting) using a suitable PSA diagnostic.
– During assembly, do not make mechanical adjustments to the unit or connectors and avoid using inappropriate chemical preparations on the contacts.
– After assembly, carry out a test drive, check the function of all gear stages, smooth start-up and any error codes in the system memory.
The correctly selected ECU of the robotic transmission for Citroën C4 will help restore comfortable and smooth shifting, reduce the risk of emergency modes and extend the life of the entire transmission system. Thanks to the exact identification according to the numbers 9663876280, 2529WR and 2531A0, this is a specific, unambiguously traceable part suitable for a targeted repair.
