I am having a problem with my 03 E270 CDI
I a tune up shop to have it re-maped a while after that the engine management light came on and we cant seem to get the blinking thing out . Im not sure if the re-map caused the problem or if it would have happened any way when connected to a diagnostic tool it Gives out the following message
2025-
"check component fault B28/5 (preasure indicator downstream of air cleaner)The atmospheric preasure between component B28/5 ( preasure indicator downstream of air cleaner ) and component N3/9 (CDI control module) is implausable "

we have replaced a few of the different sensors going through the process of illimination but we cant find this sensor B28/5

We have tried all the usual "auto data" type information but to no end
I believe the engine is a 211-016

any help would be much appreciated

The generic code P2025 is for the evaporative emission fuel vapour temperature sensor - range/performance.

There is a thermovalve for the EVAP system which could be causing this fault but I don't know of its exact location.
