Hi people am pretty new to this so go easy while I find my way around. As usual I wont be the first to open a new thread with a problem so I'll try to pick some brains if thats ok. Well here goes... I bought a 2004 C220 CDI in june and its been running like a clock. It's just done 80,000 so its average mileage. Today I came across my first problem which is loss of power and it's pretty flat and useless to overtake anything. Anyway I now have a warning and a spanner symbol and below that it says Exh,filter Carry out service in 30 miles. Thats really all it's telling me. Has anybody had this problem and what is the remedy? Many thanks guys and as I say I'm new to forums and to MB. Hope you can help.
