Dacia Engine Control Units ECU – Search by Part Number

Dacia Engine ECU – ECM and Engine Computer

A Dacia engine control unit is the electronic module responsible for managing engine operation. Depending on the vehicle and ECU generation, it can control fuel injection, turbocharging, emissions-related functions and communication with other vehicle systems.

The same component may be searched for as:

• Dacia engine ECU,
• Dacia engine control unit,
• Dacia ECM,
• Dacia engine computer,
• Dacia injection ECU,
• Duster ECU,
• Logan ECU,
• Sandero ECU,
• Dokker ECU.

Regardless of the terminology, the complete numbers from the original module should be the main reference when choosing a replacement.

How to choose the correct Dacia engine ECU

The same Dacia model can use several different engine controllers depending on engine version, production period and electronics generation.

Before ordering, compare:

• complete Dacia OEM part number,
• Bosch, Continental or Siemens manufacturer number,
• all suffix letters and digits,
• ECU family such as SID306 or SIM32 where applicable,
• HW and SW references if present,
• vehicle model and engine version as supporting information.

A similar ECU housing or the same engine capacity does not automatically confirm compatibility.

Dacia OEM numbers – 23710... and 8200...

Dacia engine controllers often carry vehicle-specific numbers beginning with families such as:

• 23710...,
• 8200....

These numbers should be compared in full. The prefix alone does not identify one specific ECU.

Examples from the catalogue include:

• 237102213R,
• 237101496R,
• 8200672654,
• 8200672644,
• 8200661124,
• 8200598393.

Bosch Dacia engine control units

Bosch engine control units are widely used in Dacia diesel applications.

Common Bosch ECU references include numbers beginning with 0281.... The complete ten-digit number should be checked together with the Dacia OEM number.

Dacia 1.5 dCi – Bosch 0281030439 / 237102213R

One current example is the Dacia 1.5 dCi Bosch 0281030439 / 237102213R engine ECU.

Important references include:

• Bosch 0 281 030 439,
• 0281030439,
• 237102213R.

Using both the Bosch and Dacia references gives more precise identification than searching only for “Dacia 1.5 dCi ECU”.

Dacia Dokker – Bosch 0281019147 / 237102213R

The catalogue also includes the Dacia Dokker Bosch 0281019147 / 237102213R ECU.

Its main numbers are:

• 0 281 019 147,
• 0281019147,
• 237102213R.

This is a good example of why the complete Bosch number matters: the Dacia OEM number 237102213R can appear together with different Bosch references. The complete label should therefore be compared.

Continental SID306 – Dacia Duster

Continental electronics are also used in Dacia engine-management systems.

One confirmed example is the Dacia Duster SID306 S180095105A / 237101496R engine controller.

The important references are:

• SID306,
• S180095105 A,
• S180095105A,
• 237101496R.

The SID306 designation identifies the ECU family, but the full S180... and OEM numbers are required for accurate identification.

What does SID306 mean on a Dacia ECU?

SID306 identifies a family of diesel engine control units. Several different versions can exist within the same family.

For this reason, searching only for “Dacia SID306 ECU” is not precise enough. It is better to use a full combination such as:

SID306 S180095105A 237101496R

Siemens SIM32 – Dacia Logan

Siemens engine electronics are found in selected petrol Dacia applications.

An example is the Dacia Logan 1.4 Siemens SIM32 S120204120A / 8200672654 / 8200672644 ECU.

Important references include:

• SIM32,
• S120204120A,
• S120204120 A,
• 8200672654,
• 8200672644.

The SIM32 family name alone does not confirm compatibility. The complete Siemens and OEM references should be compared.

Dacia Logan and Sandero – Continental S110140023A

Another example from the catalogue is the Dacia Logan / Sandero 1.6 Continental S110140023A / 8200661124 / 8200598393 ECU.

Its useful identification numbers include:

• S110140023 A,
• S110140023A,
• 8200661124,
• 8200598393.

If several references appear on the original ECU, it is best to compare the complete set rather than only one number.

S110, S120 and S180 numbers

Continental and Siemens controllers used in Dacia vehicles can carry different reference families, including:

• S110...,
• S120...,
• S180....

These prefixes represent broad electronics families and should not be used by themselves to determine compatibility.

Examples include:

• S110140023A / 8200661124,
• S120204120A / 8200672654,
• S180095105A / 237101496R.

Dacia Duster engine ECU

When searching for a Dacia Duster ECU, the engine version and complete controller numbers should be checked carefully.

A Duster fitted with a SID306 controller should be identified using the full combination printed on the original unit rather than only the model name or SID family.

For example:

Dacia Duster SID306 S180095105A / 237101496R

Dacia Logan engine ECU

Dacia Logan uses different ECU families depending on the engine and production version.

Examples in the catalogue include:

• SIM32 S120204120A / 8200672654 / 8200672644,
• Continental S110140023A / 8200661124 / 8200598393.

This demonstrates why “Dacia Logan ECU” alone is not enough to identify a replacement.

Dacia Sandero engine ECU

Selected Dacia Sandero versions share ECU families also found within the Dacia range, including Continental S110... units.

For example, the catalogue contains a Logan / Sandero unit identified by:

• S110140023A,
• 8200661124,
• 8200598393.

The original ECU label should always be checked before purchase.

Dacia Dokker engine ECU

One confirmed Dacia Dokker controller is:

• Bosch 0281019147,
• 237102213R.

See the Dacia Dokker 0281019147 / 237102213R engine ECU for the complete product details.

Common symptoms of a Dacia ECU problem

Possible symptoms of an engine-control problem may include:

• engine does not start,
• intermittent starting problems,
• loss of communication with the ECU,
• limp mode,
• reduced engine power,
• irregular engine operation,
• internal ECU fault codes,
• missing control of selected engine circuits.

These symptoms do not automatically prove that the ECU itself is faulty.

No communication with the Dacia ECU – what should be checked?

Before replacing the engine controller, check:

• ECU power supply,
• ground connections,
• fuses and relays,
• connectors and pins,
• CAN communication wiring,
• water or corrosion damage,
• vehicle-side electrical faults.

No communication can be caused by internal ECU damage, but also by a problem elsewhere in the vehicle.

Does a used Dacia ECU require programming?

There is no single replacement procedure for every Dacia ECU.

Depending on the controller and vehicle, available options may include:

• locked used ECU,
• ECU prepared for programming,
• reset or unlocked ECU where supported,
• data transfer from the original controller,
• ECU cloning,
• Plug & Play preparation where technically possible.

Not every option is available for every ECU. See our ECU preparation options for more information.

Can a Dacia engine ECU be cloned?

For selected engine controllers, required data can be transferred from the original module to a compatible replacement ECU.

The possibility depends on the ECU family and condition of the original unit. If the old ECU cannot be read, another preparation method may be required.

Why the complete ECU number is more important than appearance

Two controllers may:

• use the same housing,
• have identical connectors,
• belong to the same ECU family,
• be fitted to similar Dacia models,

while still containing different software, hardware or vehicle-specific data.

For this reason, always compare the complete label.
