nimbuye5 Posted October 11, 2023 Share Posted October 11, 2023 Greetings. I own a 2012 B180 W246 Blueefficiency CDI automobile. The vehicle has accumulated a mileage of 190,000 kilometers and continues to operate reliably. The functionality of the ECO mode has ceased to operate in recent times. Upon connecting the vehicle to a diagnostic unit, the only identified issue is related to the air suspension system. Not acceptable (The absence of air suspension in the B180 was not anticipated by me). Additionally, an examination was conducted on the primary battery... The concept of maintaining a healthy voltage. Are there any more suggestions for alternative measures to investigate or attempt? Quote Link to comment Share on other sites More sharing options...
CelestialSeeker Posted October 11, 2023 Share Posted October 11, 2023 If you are referring to the intermittent stop/start behavior, it is likely attributed to battery depletion. I have personally seen this phenomenon for the last three years, although the vehicle still initiates without any issues. Additionally, my device presents issues with the functionality of several functionalities, including the absence of secondary door locks.

nimbuye5 Posted October 11, 2023 Author Share Posted October 11, 2023 Thank you for providing this information. I have had a such problem as well. The primary battery has been verified as functioning well, since it underwent testing last week. However, there is a possibility that the auxiliary battery may be the source of concern. I will verify the information and provide a subsequent report. Quote Link to comment Share on other sites More sharing options...

CelestialSeeker Posted October 11, 2023 Share Posted October 11, 2023 It doesn't seem to have a spare battery. Quote Link to comment Share on other sites More sharing options...
nimbuye5 Posted October 11, 2023 Author Share Posted October 11, 2023 The location of the component is situated inside the front passenger footwell, positioned above the fuse board and concealed under a protective cover. (I conducted a verification process to ensure the accuracy of my statement...) Your statement caused me to question its validity. Quote Link to comment Share on other sites More sharing options...

MidnightMarauder Posted October 11, 2023 Share Posted October 11, 2023 The functionality of my b180 is similarly compromised while operating in eco mode. An error message indicating "auxiliary battery failure" is being shown on the control panel. Quote Link to comment Share on other sites More sharing options...
