Customer Question

I have a CLK200k, 2002 (2003 model, newer shape) Elegance. 66,000 miles, always well maintained and serviced.
Engine warning light kept coming on, codes showed various sensors so all have been changed. Even replaced fuel filler cap in case air was leaking in to system.
Was fine until I refilled with fuel and the light has come on again.
There is also a smell of rich exhaust fumes when the car first starts, though this stops after a few minutes when it is warm.
Any thoughts would be much appreciated.
