My 2007 Ml350 w 150k miles running very well. Recently ABS, ESP inoperative appeared but the car runs normally other than at vey low speed, such as parking, the power steering is gone. Replaced all the abs/wheel sensors, the previously mentioned remain. I leaned from one of the threads in this forum that pulling fuses for the ESP will de-activate the function, which I did. With the fuses, 109 and 115, pulled, car will still start with ESP on (no ABS now) but engine runs at a very low/weak idle and shake/vibrate significantly as if it’s going to die at anytime (and it did die sometimes). With all that going on, gas pedal is not working at all, seems to be dis-functioned, so no way to pump gas. The strange thing is that when I put the fuses back, the car behaves the same.

I’ve cleared codes (all kinds as you can imagine) with a BlueDriver Pro scanner, dis-connected batteries (main and auxiliary) over-night, the car behaves the same – low idle, shake/vibration and gas pedal not working. I thought after putting the fuses back on, it would drive the same as before I pulled them, but obviously not. Does the ECU stores the information that can’t be cleared? And the info prevents the car from starting normally? I’m completely puzzled …..

Really appreciate anyone here could share some similar experience and maybe solutions, or any comments that could shad some light on the issue!

Thanks you much in advance!

First thing is first, do a complete scan of the car and post the codes that you get including what module has what codes. No one can help you just by you describing what the car is doing. Also, stop pulling fuses. You will not accomplish anything by doing this.

thanks for the reply. sure the codes are in the attached report. You can see that there are so many of them. I think they are related to "pulled ESP fuses" situation, but the thing I dont understand is that after fuses put back, the car still behaves the same and the codes are the same, even though I've cleared all the codes with BlueDriver Pro and dis-connected batteries for over-night. It seems ECU saved the codes which can't be erased, and the ECU prevents the car from operating normally.

does it make sense to you at all?

pulled fuses are just like blown fuses, once replaced car should be normal again?!

truly confused!

thanks a lot,

Stop pulling fuses.

Delete them all and then test drive. Then check for codes again.

glmlsdus

thanks. yes, I did. still the same as discribed in my first thread. could starting car w/o the fuses damage other devices or sensors?

Maj. Dundee

Are you saying that after you delete all the codes and then you recheck for codes, you are getting the same codes that you originally posted?

If yes is the answer, then you have a massive problem.

And yes, removing fuses will pose problems elsewhere.
