W123 E,CE,D,CD,TD,TE Class
I need advice, I bought a 230E three months ago. I got the same fuel consumption as stated in the manual, but I had to replace the exhaust.
Afterwards the fuel consumption dropped from about 10km/l to 7.5km/l on the open road and in town from 8 km/l to 4 km/l.
I have tried everything...
