Emission warning light came on

[mattycraft]

Having spent a couple of hours in traffic up the M5 yesterday, the orange emission warning light has lit on the dashboard on my E200K. Does anyone know what is the best course of action? Is the only solution to visit the Merc men?

Thanks in advance.

you will need to get the fault codes read to see what the fault is

take it to somebody who has a machine to do this

fixed

well, after a diagnosis, the MAF sensor was replaced, at great expense, and the light is now out.

This maybe another oil contamination issue.
