GL350 Lost power/limp mode - Error code P2454
Out of the blue today, while my wife was driving the car, it basically had no power in the morning.
Later on her way back she said it was fine, till she hit a hill, and she lost 90% of power, and limped on and off home, and then it threw CEL, which I checked, and it says; "P2454 Aux Emissions Controls"

Is this the pressure differential sensor problem ?

Spent a $100 on a new DPF Pressure sensor from the dealer, and that fixed the limp mode, and the error...

That will hopefully carry us through another couple of thousand miles, before something else break ......
