Description

BMW Engine Control Unit (ECU) failure is a common problem on all BMW vehicles. As with any electronic component, ECU failure occurs due to parts reaching the end of their life span, voltage spikes or because of water damage.

Fortunately for you, the ECU Pro offers a BMW ECU Failure Testing service that will test your ECU for only $89. If your ECU is faulty, we can offer you a replacement ECU. If your ECU is not faulty, we will return your original ECU.

BMW ECU failure can be identified by visual inspection or by reading fault codes from the vehicle. To read fault codes you need a fault code reader. If you do not have a fault code reader any garage will be able to read the fault codes for you. Below are some common BMW ECU failures that we can test for with our BMW ECU Testing Service:

  • Symptomps of general DMW ECU failures: $200 -400 per repair depending on ECU
  • 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
  • 134B02 valvetronic servomotor supply voltage short circuit to earth
  • 12474 or 30BA injection valve failure
  • 12475 or 30BB injector 4,5,6 failure
  • Symtomps of a blown BMW ECU: $400-800 depending on ECU
  • Water damaged DME
  • Corrupted ECU coding
  • Blown DME due to jump-started vehicle
  • ECU processor failure

If you experience any of these symptoms you can send us your ECU for a repair. We will test the ECU and either repair it or offer you a replacement ECU depending on the damage.

Our current response time on orders is only 24 business hours. The same key can be used in the car and no additional programming is required. The vehicle will be 100% back to normal.

All our work comes with a 1-year warranty and free 30-day technical support!
