Original Bosch engine control unit designed for selected Audi A6 C6 versions with the 2.7 TDI engine. The unit has been tested and prepared as IMMO OFF Plug & Play, which means that, when correctly matched, it can be installed without programming it to the vehicle immobiliser.
Application of the Bosch EDC16CP34 control unit
- Audi A6 C6, model designation 4F,
- generation produced approximately between 2004 and 2011,
- selected 2.7 TDI engine versions equipped with a Bosch EDC16CP34 control unit.
The exact body version, engine code and gearbox configuration must be verified. Before purchasing, compare the references 4F5 910 401 L, 4F0 907 401 C and Bosch number 0 281 014 383 with the label on the control unit removed from the vehicle.
The vehicle model, engine capacity or year of manufacture alone are not sufficient to confirm compatibility. If the part numbers differ, compatibility should also be checked using the vehicle VIN.
Common symptoms of an engine control unit failure
- engine does not start,
- no diagnostic communication with the ECU,
- engine stalls while driving or has problems restarting,
- limp mode and reduced engine power,
- irregular engine operation or problems with injection control,
- recurring faults affecting several sensors or actuators at the same time.
Similar symptoms can also be caused by faults in the electrical system, power supply, ground connections, CAN bus or other vehicle components. A complete diagnostic check is recommended before replacing the control unit.
Programming and preparation of the Audi A6 control unit
The module is supplied as IMMO OFF Plug & Play. The immobiliser function in the engine control unit has been disabled by software, so the ECU does not normally need to be programmed to the key, instrument cluster or other vehicle security components.
After installing a control unit with matching part numbers, the vehicle should start without carrying out the standard immobiliser adaptation procedure. Diagnostic functions and communication with the control unit remain active.
Depending on the condition of the original ECU and the customer's requirements, the following services are also available:
- complete cloning of data from the damaged control unit, provided its memory can be read correctly,
- transfer of the original software and vehicle configuration,
- preparation of the replacement control unit using data supplied by the customer,
- performance tuning to increase engine power and torque,
- optional EGR OFF or DPF OFF preparation.
Tuning services, EGR OFF and DPF OFF are carried out only on request. Their use must be appropriate for the intended purpose of the vehicle and comply with the regulations applicable in the country where the vehicle is used.
Frequently asked questions
Does the 4F5910401L control unit fit every Audi A6 C6 2.7 TDI?
No. This control unit is used only in selected Audi A6 C6 versions. Before purchasing, all references on the original ECU label should be compared, as different control unit configurations were used with 2.7 TDI engines.
Does the Bosch 0281014383 engine control unit require coding after installation?
The offered IMMO OFF version does not need to be programmed to the immobiliser. When the part numbers match, the control unit is prepared for installation and for starting the vehicle without the standard security adaptation procedure.

The safest option is to use a control unit with an identical set of references. Both numbers are shown on the module label and should be compared together with the Bosch manufacturer number.
Can the EDC16CP34 control unit from an Audi A6 2.7 TDI be cloned?
Yes. Complete cloning is possible if the data from the original control unit can be read correctly. This allows the software and configuration from the original ECU to be transferred to the replacement module.
Are tuning, EGR OFF or DPF OFF available for the 0 281 014 383 control unit?
