Hello, can anyone help by deciphering these codes off my local garages diagnostic computer? Nobody seems too sure! I have an 2009 E350 Coupe. Can this be the dreaded DPF filter?!
11DA00 - Lower limit value of component B28/(DPF) was dropped below/not reached
118D00 - Component B28/8 DPF has plausibility error

Engine management light had come on so I took the car in to have it checked, these are the readings that came back. The other morning car was cruising at higher revs than normal with a clunky auto box change and no kickdown, re-set that as per google instructions! (turn off, depress accelerator etc}, everything sweet, puffs of smoke from underside then light goes out and been fine since!!! {touchwood}. I am intrigued, any help would be greatly appreciated!
