I bought a new Jeep COMPASS of 2012 year 5 months ago from our official dealer of Jeep.
Specifications say it has 11.7 Lt per 100km petrol consumption in urban cycle.
Mine has 21-22 litres per 100km.
I went to official service in Baku/Azerbaijan, but they can say me nothing.
Now after 7000km of driving my MIL(check engine) light is illuminated.
I used 93 octane petrol. Acceleration was poor. Now I use 95 octane.
Acceleration is a little improved. MIL light turned off after a while, but yesterday it illuminated again. I visited our "service" center again. They said our computer is frozen and we can't diagnose any more. Please come another time. Even with computer they can't diagnose normally. We don't have any other service center for Chrysler, Dodge, Jeep.
Please help, what can I do myself to diagnose my car ?
