A Full Test and Repair of the Mercedes CPC 3


Mercedes CPC 3 failure is a common issue across the Mercedes MP4 Actros, Arox, Antos, EvoBus, Citaro, Setra, and Tourismo.


At Alliance Transport Technologies we have worked with our customers to identify the common faults on this unit and how we can fix them.  The most common faults that we see relate to communication issues and accelerator faults.


When we receive a unit to fix, we will talk to you about the faults that you have seen and then use our diagnostic equipment to test thoroughly for that fault as well a more thorough inspection of the unit.  We will then fix the faults we have found using components that satisfy our stringent quality criteria – and we believe we apply a higher quality standard than the manufacturer.  Therefore, we are happy to offer a 2-year warranty on our fix.
