Ford Mondeo and Kuga diesel engines won’t start due to faulty engine ECU

Mondeo and Kuga ECU fault

This engine ECU fitted to Ford Mondeo (Mk IV) and Ford Kuga (Mk II) diesel engines is a common failing module that will prevent cranking and start of the engine. When the ECU completely fails you will find that the engine management system fails to achieve communications with your diagnostic equipment. Instead there will be loss of communication fault codes from other electronic modules on the vehicle.

Symptoms often begin intermittently with limp mode being activated, the vehicle cutting out and then being unable to restart. At this stage the Mondeo/Kuga ECU may store fault codes relating to sensor voltage references and ECM/PCM power relay de-energised performance. The message ‘Engine Malfunction’ may appear on the dash along with the illumination of the engine management warning light.

This ECU failure not only affects Ford Mondeo and Kuga diesel models but also: C-Max, Focus, Galaxy and S-Max.

As market leaders in remanufacture services, our in-house R&D team have identified that these Delphi DCM3.5 engine ECUs all suffer from manufacturing defects and have developed a solution to get you back on the road as quickly as possible. Before this solution was available main dealerships and specialists would purchase new from manufacturer. However, the defect has not yet been worked-out by the manufacturer, meaning that even new ECUs are predisposed to fail.

We can now rebuild your Ford Mondeo/Kuga diesel engine ECU within 1-2 working days and return it back to you without the need for programming at a fraction of the cost of new.

 

Common Failure symptoms:

  • Will not crank
  • Not running / none start
  • No communication to ECU
  • Cutting out
  • Limp mode
  • Engine management light (EML) illuminated
  • ‘Engine Malfunction’ message on dash

(These fault symptoms can be intermittent or permanent)

 

Common fault codes:

  • U0100 – Lost Communication With PCM
  • U0401 – Invalid Data From PCM
  • P06A6 – Sensor Reference Voltage A Malfunction
  • P06A7 – Sensor Reference Voltage B Malfunction
  • P06A8 – Sensor Reference Voltage C Malfunction
  • P0606 – PCM Processor Fault
  • P060C – Internal Control Module Main Processor Performance
  • P0194 – Fuel Pressure Sensor Intermittent
  • P068A – ECM/PCM Power Relay De-Energised – Too Early

 

Affected Vehicles:

  • Mondeo (Mk IV) 2007-2015
  • Kuga (Mk II) 2010-2015
  • C-Max (Mk II) 2010-2015
  • Focus (Mk III) 2011-2015
  • Galaxy (Mk III) 2010-2015

Test and rebuild:

Using our bespoke HIL (Hardware In-the-Loop) test rigs each Mondeo/Kuga engine ECU is tested beyond operating parameters both before and after the rebuild. This ensures that the ECU will meet, and even exceed, OEM standards. Using components that are higher rated than standard, we know that a rebuilt ECU will outlast the vehicle.

 

Programming:

This ECU is programmed to the vehicle, all coding information is retained during test and rebuild so that when you receive your ECU back from us, it’s just plug and play.

 

Quality:

Franchise dealerships and specialists across the globe benefit from our services. Our work defect rate is lower than 0.49% on all rebuilds, because of this, and our strict quality control guidelines, we can confidently provide an unlimited mile Lifetime Warranty.

 

Warranty:

Lifetime unlimited mileage*
