Why don't my 2010 Mercedes Benz 350 ML won't crank

GurlMechanic46 from United States 8 months ago

After replacing my battery, car required voltage to be between 12.8-14 volts and i supported the initial start with a jump. Then let it run 15-20 min idle. Also, the aux ( secondary battery) had to be replaced for the crank. Make sure aux pos and neg terminals arent in contact with any metal sides of compartment if under seat. Then monitor for draining componants like not latched doors, dirty sticky power buttons, and fuses

Signal lights did not work this am... on road trouble shooting- 4 way flashers work. Looking for signal light fuse location first... then signal switch on steering wheel.

Mine was in limp mode no crank no start. Replaced the main battery and aux battery. Needed at least a 12.8-14 voltage to not only start but more importantly to go into gear! Also first crank i supported with a jump, then let run idle for 15-20 min. Module resets for transmission and ESPwere essential.

My electric sockets are not working and I already changed the fuse that belongs to the group
Does anyone know if maybe there is a relay or something else that I have to replace in order for this to work?
