COMMON MSV70 / DME FAILURE SYMPTOMS

A failing or damaged MSV70 can potentially cause:

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

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