Hello,

I just changed my main battery at the truck but I still get the red battery alert light on the dashboard, I also checked to see if my alternator is charging, and it shows that it is charging properly. I have also checked the Aux battery for life and it reads above 12.50. My car goes off after a while after the a/c trips off and the Car stereo goes off and on.

Car model: E240 2003 model

My air flow meter is giving me nightmares, I drive a Mercedes Benz(211) E500 2005 model and just of recent I started having air flow meter issues, when i am on transit and break for a bump or slowing down, the car goes off, an analysing machine was used and found the issue to be the air flow meter and some days ago, the radio and navigator refused to come on, when I press power it comes on then go off, I also changed the air flow meter like 8 times but, still having same problems, what do I do please?

In reply to Delian. I would suggest that you call your dealer and ask them what the part number should be for that module. Also what battery did you use? Was it aftermarket?

hi there, i recently purchased a second hand Merc e220 w211 (2005) and this message appears every saint day. i changed the auxiliary battery … but nothing. so i bought a delphi car diagnose system that helped me to identify the problem : BATTERY ENERGY CONTROL MODULE – BSG211 —> DTC : 9051 CONSUMER SHUTOFF STAGE 1(PERMANENT) and second DTC: 9050 CONSUMER SHUTOFF, STAGE 2(INTERMITENT). After erasing them, they still appear . But the problem that i have now is this one : i physically inspected the module at the back of the trunk but the part number is not the same as the one that is stated by Delphi. So, on the back, in the trunk i have A211 540 42 45 (that has a hand made hole in the casing and a white wire attached to mother board) but Delphi is reading from the ECU the following PART NUMBER : A211 442 01 55 .please help me
