A6421501272 / 0281014204 – Mercedes 3.0 CDI CR4.30 VIRGIN engine control unit

The offered engine control unit with numbers A6421501272 and 0281014204 is a Bosch CR4.30 unit prepared in VIRGIN state. The module is cleared of immobilizer data and ready for first start in the vehicle after completing the programming procedure using Xentry / Star Diagnosis. This is a safe solution in case of original ECU failure or communication problems.

Application

This ECU is used in Mercedes vehicles with the 3.0 CDI V6 (OM642) engine. Depending on equipment version it can be found for example in:

  • E-Class (W211 / W212)
  • C-Class (W204)
  • S-Class (W221)
  • ML / GL / R

Typical years: around 2006–2013 (depending on calibration and software number).

VIRGIN version – what does it mean?

The unit has no VIN stored and no synchronization with the immobilizer. After installation it must be assigned to the vehicle online or offline via Xentry / Star Diagnosis. For workshops without access to coding we also offer a cloning service of the content from the damaged module.

Typical failure symptoms

  • engine cannot be started
  • no communication via OBD
  • random injection faults despite correct wiring
  • engine stalls while driving
  • no control of relays or cooling fans

 

FAQ

Is A6421501272 ready to drive after installation?
No – this is a VIRGIN version. After installation programming in Xentry or Star Diagnosis is required.

Can 0281014204 be installed without coding?
Only after cloning data from the original ECU. Otherwise adaptation is required.

I have a damaged A6421501272 module – can the data be transferred?
Yes, in most cases it is possible to copy FLASH and EEPROM, so the vehicle will start without additional procedures.

How to choose the correct 0281014204 ECU?
It is best to compare the Bosch part number and the Mercedes number from the label or send them for verification before purchase.

Each engine control unit passes a power supply and communication test before shipping.

      Audi Q7 3.0 TDI Water Damaged Engine ECU| 4L1910401D & 4L0910401G IMMO OFF Plug & Play

      Audi Q7 3.0 TDI won’t start after heavy rain? The engine ECU could be water damaged

      One of the most common failures in the Audi Q7 3.0 TDI is water damage affecting the Bosch EDC17CP04 engine ECU. This issue frequently impacts units 0281015868 and 0281014174, which are mounted beneath the windscreen scuttle panel, an area highly exposed to moisture and blocked drainage channels that can lead to corrosion inside the ECU.

      In this article, we explain the typical symptoms of a failed Audi Q7 3.0 TDI engine control unit, when ECU cloning is still possible, and why in many situations an IMMO OFF Plug & Play solution is the fastest and most reliable repair option.

      0281015868 & 0281014174 – common ECU failures in the Audi Q7 3.0 TDI

      Learn why engine ECUs such as 4L1910401D and 4L0910401G are especially vulnerable to water ingress, which fault codes usually appear during diagnostics, and how professional ECU repair or replacement is performed for the Audi Q7 3.0 TDI.

      Water-Damaged Bosch 0281013691 / 4L0910401K ECU – Common Audi Q7 3.0 TDI Engine Control Unit Failure

      Water Damage in Bosch 0281013691 / 4L0910401K ECU – A Common Audi Q7 3.0 TDI Failure

      The Bosch 0281013691 / 4L0910401K engine control unit fitted to the Audi Q7 3.0 TDI 4L is well known for being vulnerable to water damage. In many cases, the issue is caused by the ECU’s location beneath the windshield cowl, where moisture and rainwater can accumulate over time due to blocked drainage channels.

      Symptoms of a failing ECU may appear gradually or occur suddenly after heavy rain, a car wash, or long periods of vehicle inactivity. Common signs include no communication with the engine control module, intermittent or complete no-start conditions, CAN bus communication faults, and in severe cases, a completely dead ECU in the Audi Q7 3.0 TDI.

      Similar problems frequently affect other Bosch EDC16CP34 units installed in the same location, including 0281012772 / 4L0907401, 0281012919 / 4L0907401, 0281013689 / 4L0910401M, and 0281013690 / 4L0910401L. These engine control units share nearly identical hardware architecture, with the main differences relating to software versions and vehicle-specific configuration used across different Audi Q7 3.0 TDI variants.

      In this article, we explain the most common failure symptoms of the 0281013691 / 4L0910401K ECU, the typical causes of water intrusion, CAN communication issues, and a practical solution in the form of a ready-to-install IMMO OFF Plug & Play engine ECU that works without immobilizer programming or data cloning.
