Fuel consumption (Diesel) SSANGYONG Korando C200

Hi you all,

I bought this car in 2012 and have it as single owner, very good car and lots of power with the E-XDi 2 liter diesel turbo motor.

I use to get good fuel consumption (8.0l/100 km) but the last 12 Months it was getting worse (11.5l/100 km). I changed about all sensors that is possible to change and the car keeps on idle uneven with start up. Unfortunatly no agents available in South Africa as it withdrawn from our Country. Does anybody know of the same problem? On the diagnostic test it doesn’t shof any codes.
