2003 and newer DEM’S suffer from a variety of failures from communication issues to total network shutdowns. They are also prone to water damage, resulting in an even broader range of failures.

In 2005 and newer models it is also possible for the Rear Electronic Module (REM) to cut off the power supply to the DEM. We strongly recommend that you consult our DEM Diagnostic Flow Charts to correctly diagnose the failure.

We also recommend that the Haldex feed pump is tested prior to reinstalling a rebuilt DEM. These pumps can seize-up creating a short circuit. Your freshly rebuilt DEM will be destroyed instantly as a result.

In order for us to correctly address and assess the repairs needed to be done you would need to send in your DEM for a repair estimate. Once we have received your DEM we will test and inspect it and then provide you with an estimate on your unit. We have divided the repair in to two different repair levels, Basic Level 1 and Advanced Level 2. These are based on the nature of the failure and how extensive the repair may be. Additionally, if your DEM is damaged resulted from water intrusion, additional water damage repair charges will apply. During checkout you will be charged for the basic repair service, should your unit require additional repair we will contact you prior to proceeding.
