Bosch 0281013013 OEM 4L0910409 – IMMO OFF set of 2× ECU ENGINE CONTROLLERS for Audi Q7 4.2 TDI

4L0910409 / 0281013013 is a complete set of two ECU ENGINE CONTROLLERS used in the Audi Q7 4.2 TDI. This offer includes a pair of ECUs designed to operate together in one vehicle, professionally prepared in IMMO OFF Plug&Play version – ready for installation without coding, adaptation, or programming.

The most common failure affecting the 4L0910409 / 0281013013 ECUs in the Audi Q7 4.2 TDI is water damage. Water enters the ECU compartment located under the windshield cowl, causing corrosion of the electronic components and CAN communication issues. In most cases, the ECU marked as MASTER becomes damaged.

IMPORTANT:

IMMO OFF is only possible when purchasing the complete set of two ECUs.
Both units sold as a set must be installed together in the same vehicle.

The ECUs are marked as MASTER and SLAVE and must be installed according to their designation:
– MASTER mounted vertically,
– SLAVE mounted horizontally.

The ECUs cannot be swapped between positions.

The IMMO OFF Plug&Play version works without programming after installation. Software updates for the ECUs or the vehicle must not be performed, as updates may restore the factory immobilizer protection and disable the IMMO OFF function.

Compatible vehicles:

  • Audi Q7 4.2 TDI
  • engine: 4.2 TDI V8
  • production years: 2006–2010


The 4.2 TDI V8 engine is factory-equipped with two original engine ECUs operating together as a matched pair. With this set, both ECUs are prepared in IMMO OFF mode, eliminating the need for immobilizer synchronization after installation.

Each product is professionally prepared, electronically tested, and verified before shipping. The ECUs are ready for immediate installation and operation.
