I have a 2013 s550 4matic with amg sport package and face lift. It has happened to me a couple times now. I will go to start car and It starts for a few seconds then I see
Presafe innoperative see owners manual then
Parking guidance inoperative see owners manual.
The command screen will be completely black
And the car will shut off. Then I get a check engine light on saying (cheap scanner UO109) fuel pump .
I am the proud owner of a benzninja computer and he scaned it when it was doing it and found the fault code of fuel pump. Saying I should replace the pump I explained to him the weirdest part is, the second I see command and radio turn on car starts no problem. Which I came back a few hours later and had him connected and command came on and car started no problem.
after a few starts that check engine light goes away..
He said next step would be replace auxiliary battery to see if it helps.
I replaced the battery with a Walmart h8 battery a few weeks ago. And it has still happened a couple times. Since
I cleared the rain drains when I picked up the car to try and avoid having water issues in fiuse box
I've checked fuses
I unplugged battery for 20 minutes
Just trying to get your guys opinion if anyone has had similar issues.
It hasn't bothered me until last night when I took my wife and son on a trip a couple hours away and it happened in not the greatest of neighborhood at night and it wouldn't start for 2 hours. Very embarrassing as I love the car but had my wife questioning my purchase of it after this.
Sorry it is early and my xentry is dead in my trunk so I just used the picture I had on my phone.
Why don't you post the Fault Code from your Xentry? Anyway, the U0109 seams to be related with Fuel Pump Control Module CAN communication, not the Pump itself, if you trust your Generic Scanner more than Xentry.
