Common MSV80 / DME Failure Symptoms

A failing MSV80 can potentially cause symptoms including:

• Crank but no start
• Intermittent no-start
• Engine stalling
• Rough running
• Engine misfires
• Multiple cylinder faults
• Injector-related faults
• Throttle or Valvetronic-related faults
• Reduced power / limp mode
• DME communication faults
• Diagnostic scanner unable to communicate with the DME
• DME intermittently dropping offline
• Multiple engine-management fault codes
• Internal DME faults
• Water or moisture damage
• Corrupted DME data
• Internal electronic failure

Proper diagnosis is strongly recommended before ordering. Ignition coils, injectors, sensors, Valvetronic components, wiring, grounds, power supplies, battery voltage, fuel-system problems, and other components can cause similar symptoms.
