Fuel loss

[Madds]

I have a mercedes c200 elegance, w reg the old shape year 2000 Automatic
I have recently noticed iam not getting enough miles from my mercede as a iam getting about 150 miles out of a full tank. There ain't no leakages to what i can gather.
Vehicle has been serviced. I have reset the trip and noticed its doing less miles and using up loads of fuel.
any ideas what the problem can be?
Could any one tell me how many miles I should be getting??


any comments??

Your cat could be blocking up or brakes binding maybe?

You are either losing it or burning it. If the former, could be dangerous. If the latter it will kill your catalytic converter, so either way, don't live with it for very long. The key thing that controls fuel is the MAS sensor. The ECU should detect a problem but not always. Get it checked.
