My first post and my first mercedes
I bought my car 4 weeks ago, Facelift c220 diesel auto estate full MB service history, and so far very happy, although there are a few things that need sorting but its done 99k.
It has been returning about 42 mpg combined, I commute from Somerset to Liverpool weekly and then its short (5 miles) to and from work,
However on the trip home on friday night I struggled to get 25 mpg, speed made very little difference 50 to 90 mph only 2 or 3 mpg difference according to the computer, filling up today confirmed i used £48 of diesel to do 195 miles.
Today I serviced the car replacing all the filters and the thermostat ( it was taking 10 - 15 miles to reach 80c) but no improvement in mpg, until i disconnected the MAF immediately the mpg went back up to low 40's (10 miles of A and B roads)
when I bought the car the dealer ( not mercedes ) told me the DPF had been deleted from the map and the internals had been removed, I've no reason to doubt this as i believe the remap has also increased the power over the other c220's i test drove
The car has been producing a lot of black smoke on acceleration, and on kick down its embarrassing but it pulls like a train so i thought the smoke was a result of the remap, now the MAF is disconnected the powers slightly down but the black smoke has virtually gone.
So I guess I'm going to need a new MAF ?, but my real question is, am I ok to keep the MAF disconnected until I fit the new MAF ?
Many Thanks for any advice you can give
