Vehicle ECU failure and symptoms.

Much like other electronic components, vehicle ECU failures are widespread and can be due to several reasons.

Finding out what caused your vehicle ECU failure can help determine whether you need an ECU repair or a replacement ECU. The ECU Pro offers vehicle ECU replacements / repairs that are more affordable than OEM repairs.

Below are some common vehicle ECU failure symptoms:

• Injector driver faulty
• Cylinder Misfires
• C9304 BSD databus communications fault
• Internal Valvetronic failure or Valvetronic under-voltage detected
• No ignition spark on one cylinder
• 133902 DME internal fault
• 134B02 Valvetronic servomotor supply voltage short circuit to earth
• DME Master relay Activation
• Intelligent battery sensor (IBS) related codes
• 12474 or 30BA injection valve failure
• 12475 or 30BB injector 4,5,6 failure
• Water damaged DME
• Corrupted DME coding
• Blown DME due to jump-started vehicle
• DME processor failure

If you experience any of these symptoms you can send us your vehicle ECU for a repair or replacement service. Once we receive your vehicle ECU our professional team will conduct a comprehensive test and diagnostic check on the ECU. Our team of specialized technicians can then recommend a repair or replacement ECU, depending on the results.

If no fault is discovered and your vehicle ECU is in working order, your original ECU unit will be returned. All our repair and replacement services are Plug and Play solutions. Once we have completed the repair, the vehicle will be 100% back to normal and no other programming is required.

All our work comes with a 6-month warranty and free 30-day technical support!

ECU repairs / clone highlights:

• 100% plug and play - There is no additional coding required.
• 3-6 day turnaround - Most of our repairs/clones are completed within 5 days. Time is impacted by the availability of parts and the extent of the damage to the unit. Some units can take between 5-10 days.
• 6-month warranty - All our ECU repairs / clone come with a 6-month warranty.

• How does the vehicle ECU mail-in repair process work?

1. Remove your ECU from your vehicle.
2. Mail us your part. We do not provide a part collection service.
3. We will recommend either a replacement or repair service.
4. Once we have repaired your part, you can fit it back into the vehicle. All our repair and clone services are 100% plug-and-play, and no additional services will be coding will be required.

• Can a vehicle ECU be repaired?

Yes, a BMW DME can be repaired. First, a diagnostic check is needed to be done on the damaged DME to assess its repairability. If possible, a DME can be repaired and restored. Alternatively, a refurbished replacement DME can be installed.

• How to identify a failed ECU on a vehicle?

Identifying if your ECU has failed and what faults are present is the first step in replacing or fixing your damaged ECU.

The most basic tests to determine if your ECU has failed are:

1. OBD fault codes - Most diagnostic scanners can read fault codes from the ECU. If there are fault codes relating to the ECU, it can be a good indication that the ECU is faulty. If there is no communication with the ECU, the ECU might be faulty.
2. Visual inspection - Look for water damage or any other physical damage to the outer case.
3. Smell Test - If you can smell burned components, the ECU is likely damaged.

If you have done the above tests or if you are unsure if your vehicle ECU is faulty, we can offer a comprehensive ECU test. Once we have done a test, we can recommend the best repair option.

• How much does it cost to fix a vehicle ECU?

A OEM BMW ECU can cost between $2000 - $4000. Fortunately, The ECU Pro offers repairs and refurbished replacement units at a fraction of the OEM repair price.

An ECU diagnostic test will need to be run on your existing ECU to see if a repair can be done, or if replacement is needed. The outcome of the ECU test will determine the cost of your vehicle ECU repair.

• What happens when there is a vehicle ECU fault?

The symptoms of different faults will vary depending on the fault. In some cases, the vehicle will not start. In other cases, there might be constant miss fires, permanent fault codes, or a completely dead ECU. Running an OBD fault diagnostic report will identify if the ECU has failed.

• What is the DME in a vehicle?

The DME, or Digital Motor Electronics, is the unit that controls all aspects of your vehicle’s electrical operations. Often referred to as an ECU in other cars, the DME (in BMW’s parlance) receives electrical signals from the engine and other components to adjust the vehicle’s performance accordingly.

• Where is the ECU located in a vehicle?

Depending on the vehicle, the ECU can be located in different places. In most vehicles, the ECU is located in the engine bay. When checking out on our website, there are detailed removal instructions for your specific vehicle.

• What is a ECU fault?

A ECU fault is when an incorrect signal is sent to the ECU from one of the controllable components or performance metrics (accelerator, throttle position, speed, airflow, air density, and air temperature).

If there is a ECU fault, your vehicle might not start, the engine light might be on or there will no communication with the ECU.

• Is DME the same as an ECU?

Yes, a DME is the same as an ECU, as BMW’s technical description for their proprietary ECU is a DME.

• Vehicle used ECU programming

Much like installing a new operating system on a computer, we can reprogram a used ECU for your BMW. Programming the used DME will function the same way as a new OEM part from BMW.
