Renault Clio 1.5 dCi ECU – Common problem

Renault Clio engine ECU fault

 

This engine ECU (DCM1.2) is a very common failure for Renault vehicles fitted with the 1.5 dCi engine built between 2002 & 2015.

The common symptom is complete non starting with no communications via diagnostic. You may also have the immobiliser light on all the time and the coolant fan constantly running, the main relay will also not function when the ECU is faulty.

 

This ECU is very expensive when purchased directly from the manufacturer or main dealer, we are able to rebuild your own unit for a fraction of the dealer cost and we give an unlimited mileage lifetime warranty with every rebuild.

 

 

Common Failure symptoms:

  • No engine start
  • No communications to the ECU
  • Inactive main relay

 

Affected Vehicles:

  • Renault Clio III (2005-2014)
  • Renault Kangoo I & II (2004-2012)
  • Renault Megane II (2002-2009)
  • Renault Modus (2004-2012)

 

 

Test and rebuild:

First, we test your ECU on our purpose built HIL (Hardware In-the-Loop) test rig, this allows us to run your ECU exactly as if it was running on the vehicle under all driving conditions. Once we have identified that your ECU is faulty, we then go on to the rebuild stage – during this stage we replace all the common failing components with higher rated versions and correct the original design flaw, this is how we are able to give such a long warranty period. Once your ECU has been rebuilt, we then test it again on the HIL rig to ensure it is functioning as new. We then ship it back to you, ready to be fitted back on to the vehicle.

 

Programming:

All programming is retained during test and rebuild, meaning that once you receive it back you can just plug and play.

 

Quality:

Due to our very high Lifetime Warranty standards, encompassing testing, components, workmanship and ESD safety, we have been the number one choice for main dealerships and specialists around the globe for many years.

 

Warranty:

Lifetime unlimited mileage*
