My '06 E55 Estate is bone stock. Just clicked over 22000 miles on the way home, going about 75 mph in the rain, the motor died

The range was still at 45 miles; I'm sure there were at least a few gallons left in the tank.

Coasted to a stop on the shoulder, and the car restarted immediately and idled nicely, but stumbled at anything more than idle.

I was able to limp it to my buddy's shop....no codes thrown.....we'll see if it's a bad fuel pump or what!

 

Let us know what happened

 

On my previous W210 E55, the same thing happened. I recall replacing the fuel pump, fuel filter and I think an EGR valve too.

 

Apparently both fuel pumps were toast. Which is a mystery to me on such a low mile car. Full autopsy results to follow...

 

Do you have the tendency to run your gas tank low? I can only think that sediments may collect and be denser in a tank low on gas and may clog up the pumps...then again there are filters.. not sure if they are built in or not.

 

I recently bought the car, but I doubt the previous owner did that. Will find out more soon....

 

Hmm interesting both pumps going bad at the same time? Hopefully you can check the condition of the fuel filter to see if sediments caused the pumps to go bad.

 

One pump may have actually been dead already and the other could've been on it's way out

 

do both the pumps perform the same function? in some cases the cars have two pumps, one pump scavenges the fuel in the tank to one area and the other one pumps it out of the tank.
