Techinical Info

The Blue&Me control unit with OE code 51905061 is a second-generation multimedia electronic module, internally identified as Lauberhorn. This module has been used on various vehicles of the FCA Group (now Stellantis), produced between 2010 and 2012.

It is a version developed as a unified spare part, suitable for multiple models of Fiat, Lancia, and Alfa Romeo brands. From a hardware perspective, the OE control unit 51905061 is identical to versions with the code 5052XXXX, but it is more versatile for applications across multiple brands.

Technical specifications:

  • Manufacturer: Magneti Marelli
  • Bluetooth 2.0 + EDR, supporting hands-free profile (HFP) and phonebook access profile (PBAP); does not support A2DP for audio streaming
  • USB 2.0 port for multimedia devices
  • AUX input on pre-wired versions
  • 7-pin connector
  • NW140 flash memory
  • Improved compatibility with smartphones and hands-free systems
  • Resolved echo issues present in previous versions

Model applications

LANCIA

  • Ypsilon

DIPA can intervene to also revise this module.

Common faults and malfunctions

Over time, the Blue&Me OE 51905061 control unit has exhibited various electronic defects, many of which are attributable to corruption of the internal NAND memory or firmware crashes.

Main fault symptoms:

  1. Failure to start and absence of Blue&Me logo

The system does not start when the vehicle is turned on. Cause: firmware crash or NAND damage.

  1. USB port not working

Devices are not detected and in some cases, charging does not even activate. Often related to internal memory problems.

  1. Unstable or non-functioning Bluetooth

The module overheats and stops working, causing connection difficulties or continuous disconnections during calls.

  1. Error messages on the instrument cluster

"Blue&Me Unavailable" or "Error Blue&Me" may indicate corrupted memory or failed software update. Attempts to update via USB often fail.

  1. Unusual battery drain

The module remains active even with the vehicle off, causing battery discharge within a few days.

  1. Firmware non-updatable

The system may freeze at boot and not recognize USB files, even after physical resets such as disconnecting the battery.

  1. Odometer flashing on the dashboard

A classic symptom of proxy alignment error or communication issues between control units.

  1. Steering wheel commands not working

Buttons may be physically worn out, or there may be a logical interruption in input management.

  1. Inability to connect for diagnostics

In case of critical damage, the module may become completely invisible to diagnostic tools.
