2013 E220D - EML - P047128
I've got a 2013 E220d, I'm having a loss of power along with the code P047128. I'm UK based and live near Wakefield/Pontefract area.
When the car is cold it drives perfectly fine, once warm it has a loss of power - delayed gear changes and struggles to get up to speed.
I've replaced the exhaust back pressure sensor for a genuine sensor from Mercedes - i've plugged my Icarsoft V3.0 in and read the values etc - shows 1.02bar pressure on idle when cold. but jumps upto 2.02 and limp mode from what I can work out. I've got the car booked into a specialist in June (earliest appointment) but I want to try and fix before this.
Any help with me making sense of the live data would be great. Or even someone who can fix it before June.
Thank you

The next item is to deal with the pipe that plugs up with soot needs cleaning/replacement.
In addition you can buy quick live access to the No1 professional repair network at www identifix dot com for exact PRO fixes specifics to your VIN at DIY cost.
