I bought this 2012 E350 Blutec about 18 months ago. I have for the second time had to replace the Back Pressure Sensor. After reviewing some articles on the Forum it appears that the continued failure of this sensor maybe the found in the failure of the DPF (Diesel Particulate Filter) to self clean.
There are DPF cleaners, Liquid Moly has one, and I wonder if anyone has used it with good results. BTW, I used Liquid Moly Diesel Purge on my old 123 300E and it worked very well!
So, I am hoping the DPF cleaner will work as well.
But, am I the only one who has continued problems with their Back Pressure Sensor? And, are there other reasons for their failure besides the DPF?
I greatly appreciate your responses.
