E550 won't turn over
This just started today. When it did start, there were no warning lights, no maintenance-needed lights, nothing and everything was working fine. It did tell me my "blind-spot" monitor was turned off and I know I didn't do this and I'm the only one who drives it.
I haven't left anything on (lights). Not sure what's wrong.
Any suggestions would be appreciated.

I was thinking it was the battery but a friend who works for a dealership was trying to convince me otherwise.
Again, thank you & I appreciate all the feedback!
The tech said a common problem with the E550 is the headlamp switch may be off but it will continue to send a signal to the car saying it's on and will drain the battery. Since the car is still under warranty they can write it up as warranty work.

My 2011 E550 has a phantom drain or some other battery issue that I haven't diagnosed yet and I'm not under warranty. Battery tests good and continues to start the car regularly. However, every few weeks or months something gets it low and then it is slow to start or worse needs a jump.
Please let us know what they find as this could help me look into my issue.
It was a little surprising as you would think I could hear it running but I didn't and that was the problem.
Fisch, my car is a 2011 and I still have the factory battery. They ran a check and said the battery was fine, just needed a little charging. Luckily I'm just barely under warranty otherwise I'd hate to think how much I'd have to pay to get the fan replaced!




Durell, mine is the factory battery also. It tested good, needs charging before but I still have issues. I would get them to charge the battery while they have it for the fan repair. That way you are fully charged when you get it back. Then I would have them check the battery again before your warranty expires just to be sure it is still holding a charge.
The evaporator fan is with the evaporator core deep inside your dash. To get at it involves removing practically everything you look at when sitting in the car. Listen in your garage after 30 minutes or so when your car is parked at the base of your windshield in the center. It is a very soft humming fan. It dries the evap coil.




My W212 seems to drain from the evaporator when it pleases. I can leave it running with AC on parked in the driveway after a drive and there is no sign of draining most of the time. I have checked the tubes for signs of blockage and not found any. It always seems to drain after my car has been parked for a while - I wonder if that is related to the fan and the drying process. One time I was in the garage after it was parked for at least 30 minutes and I heard water running quickly. Looked under the car to see if had just started draining. Maybe it's too classy to drain all the time or maybe my car needs Flomax.

We did have the oil changed while we were there so that was the only charge. I don't normally have the dealership do oil changes because the cost but the car was there and it needed it so we did it. Next time we'll go to the local MB non-dealership garage who does quality work at a more affordable price.
We bought our 2011 (with only 20k miles on it) for $33k. It came with the AMG package. We got a really good deal and are quite happy with it.
I see you have a '65 Mustang! I used to own a '67 Coupe...loved it. Had only one owner and everything was original except the engine. They pulled the 289 and dropped a 302 in it. Sorry, I'm getting off track...this is a MB forum.
