Hello, I just had the 96 000 km service on my 2002 9-3 (5 doors). They change all the oils, filters and spark plugs on the car. Also I have changed the battery because it was dying on me.
Before the service I was averaging 7.5 l / 100 km on the highways and
10 l / 100 km in the city. I do a bit more highway then city roads like
60/40. With a full tank I was able to do 550 - 650 km ... 700km if I was lucky
Since the service, my fuel consumption way up. I'm averaging 10 l /
100km on higheways and 14 l / 100 km in the city and went from 550 -
650 km to 400 - 500km with a full tank. I didn't change my driving habits.
I'm not a mechanics but I was wondering if the ECU will adjust the fuel consumption by it self. Do I need to get it programmed? By replacing the battery have I unprogram something.
Any help would be appreciated.
Season Greetings to all Saab lovers.
