⚠️ Common Signs of Failure

• Engine will not start, or cuts out with no fuel or air fault found
• Warning lamps or alarms with codes pointing at the control unit itself
• Erratic running or a hard-limited rev ceiling
• Unit will not communicate with diagnostic equipment
• Water ingress or corrosion visible in the connector or case

🛠️ Service Notes

• This one is marked Kamd, while control unit 3819874 is marked Kad - the two carry different settings, so ordering the wrong one gives an engine that runs to the wrong specification
• The superseded number was catalogued as a dataset, so a control unit and its programming may be quoted as separate things in older records
• Check the supply, earth and connector condition before condemning a control unit, as a poor earth mimics an internal fault
