Engine start, cut off within seconds, 2008 ML350 ...?


Asked by Jul 25, 2015 at 09:00 PM about the 2008 Mercedes-Benz M-Class ML350

Question type: Maintenance & Repair

I am having this issue right now. Batter died last week Sun, called AAA, guy had a hard
time jumping as battery had no life for 2 days. He went back to his truck, got a differ
machine I assume, we tried about 2 more times and it cranked. I drove that night to
charge voltage. I did have 1 time the next day put key in, didn't start, took key out,
waited a few seconds, then tried again, it started. Due to the charge, the AAA guy says I
loss memory, (sig. lights, wipers, chairs) did not work. I took to shop to have memory
reboot and oil separator leak fixed and guy is now saying my car won't start. He did
nothing. I get there and it cranks but cuts right off within 2 seconds. Pls help if any idea.
He's suggesting CAN BUS but all my research does not point to this as solution. Thanks,
April B.

Have alternator tested should be charging at 14 volts.


Thanks firebird338, well dealer came back with this as my 'Diagnosis; Various CAN communication codes. No Communication with ESP/ME/Transmission and Rear SAM control units. During inspection, found corrosion at Rear SAM connectors. Recommend replace Rear SAM and CLEAN connectors Rec' to inspect for water leak Advised may require further Diagnosis/Repair I am skeptical of this dealer and believe I have a place to take care of CAN and SAM replacements, yet scared that problems may be so complex, dealer is needed. Any feedback is most appreciated.


Is the check engine light on or the battery light ?


Remove and clean battery terminals to make sure they are nice and tight and I really do not see anything they told you has anything to do with the vehicle not starting and why do they have to replace the rear SAM try cleaning connections first before replacing saying they have to replace. Maybe that is all that it needs is to clean connection that maybe all that is wrong a bad connection.


Did you manage to fix problem? I am dealing with it now. Check Engine light on.
