Summary

Service Engine Soon Light Flashes with Throttle Adaptation Faults Stored. The EML light flashes with a check control message for reduced power output and/or the Service Engine Soon lamp (MIL) flashes. During the throttle valve adaptation (teach-in limit run), faults may occur due to signal voltage oscillations. This could lead to a termination of the teach-in routine or an incorrect value taught in at the lower limit. The following faults can be stored in the DME memory: E82, E84, E88, E89, E92, and E93 BN2000 vehicles 28D0: throttle valve, adaptation: Initial adaptation, lower limit not taught in 28D4: throttle valve, adaptation: Subsequent teach-in, lower limit not taught in 28C4: throttle valve, adaptation: Emergency air position not adapted 28A0: throttle valve angle - Intake manifold absolute comparison: pressure too high ??3166: Tank-ventilation system: fault F01, F02, F06, F07, F10, F12, F13, F30, F31, and ALPINA B7 BN2020 vehicles: 101408: throttle valve, adaptation: Initial adaptation, lower limit not taught in 107AE0: throttle valve, adaptation: Subsequent teach-in, lower limit not taught in 101402: throttle valve, adaptation: Emergency air position not adapted 101F01: throttle valve angle - Intake manifold absolute comparison: pressure too high ??190F08: Tank-ventilation system: fault Sensitivity of the throttle valve sensor (only affects parts installed during this production period)
