We specialise in restoring these modules to full working condition, often within 2–3 working days. This service includes handling faults and common failure symptoms related to Euro 6 MX-11/MX-13 Delphi DMCI ECUs.

If your Kenworth truck is hard to start, shuts off without warning, or shows strange warning lights, the ECU could be to blame. This is a common problem in Euro 6 models with MX-11 or MX-13 engines.

The Delphi DMCI ECU can fail in several ways. For example, fuses may keep blowing, or you might see communication errors. In other cases, the connectors may be damaged, or the engine might stop while driving. You may also notice fault codes for the injector circuit, or dashboard lights that appear without reason. Sometimes, the problem comes and goes, which makes it hard to find. In addition, oil or water may get into the unit and stop it from working. As a result, the ECU may become completely unresponsive.
