The connection is unstable or breaks

The vehicle’s engine compartment may interfere with the Bluetooth connection. This may cause poor reception between the eFlexFuel control unit and the connected mobile device.

Vehicle’s thick insulation or enclosed mounting of the control unit to the engine compartment can cause a poor usage.

How to repair

  • Lift the hood and try to connect with eFlexFuel. See if the connection is still unstable
  • If the connection is still unstable: 1) try to relocate the control unit. 2) Move the wiring harness away from other wires and high voltage components
  • If the connection is stable when the hood is open, it is fair to presume that the insulations of the vehicle weakens the Bluetooth signal substantially and causes the connection problems
