C220 Cdi Avant

[alfiep]

I have a merc c220 cdi auto avantgauard. I'm a forum virgin.

I have a number of issues:

25 miles per gallon, is this real?

I have a problem with the power. When I'm driving the car dramatically slows when going over small hill and gradients. The car's speed pick up is not what it was like. Very sluggish. Mechanic cant find a problem.

AC is Knackered again.

Pls advise where poss. The car has 99k FDSH.

Hello,


You might as well drive my ML and get 25


I would think something very wrong there as I would think 40mpg would be easy?


MAF sensor?


Other wil be around who know far more on the technical stuff shortly...


Cheers
