2011 e550 - Won’t start

Hey guys,

hope everyone is doing well and staying healthy.
quick question....I have a 2011 e550, 50k miles.
Hopped in today, went to push start and nothing. Fill power still, can hear maybe fuel pump, etc.

any ideas on what it could be?

thanks,
eric

Have you tried your spare key to eliminate a key issue?

Also did you check voltage at the battery too?

To know if you are getting the power to the start solenoid you would need to get under the car and measure if you get the battery voltage to the starter solenoid when someone else tries to start it for you.

I'm not sure if these cars have the first solenoid I mention, i.e. the one that would feed the starter solenoid. Older cars have the power running from the key switch when you do the starting move with the key. I would think MB would use another solenoid for this but I'm not sure.

If you measure the voltage coming to the starter solenoid and find the battery voltage there then for sure the problem is with the starter motor or the starter solenoid build in to the motor.

For the age of your car I would not be surprised if it is the starter motor/solenoid. I had to change mine at about 10 years old on my 2010 E550. Same car as yours since 2010-2011 were built the same.

Last year my 2011 E550 had to get a new starter motor - because it just did not start after stopping to get a coffee. It happened that suddenly. Without much warning - although I felt it was cranking & starting in a weak fashion for a while.

Now (see recent thread) the car has failed to start 2 times. Getting a new battery right now. Mechanic is checking out related potential contributing factors.
