Hello all.
I've been struggling with poor mpg for the past 18 months on my 2003 w211 e270. 180.000 miles
The car was very hesitant to accelerate. Especially when cold. Was only seeing 60 miles out of 16 litres of fuel. My initial thought was the vanes in the turbo. But these were completely free.
After a long process of numerous scans and elimination, nothing was showing up.
I replaced the crank and cam sensors and BANG!
It's like a new car again and mpg is instantly back to normal. These sensors determine the timing of the injection of fuel.
Hope this helps everybody.
