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.

I'm thinking that they put the wrong plugs in. There's very little to
adjust on a Saab and the things you mentioned really should not impact
mileage. Was it a Saab specific service place? If it was a non-Saab
service center, then you should ask them exactly what plug they put
in.

FYI - not sure it this applies to you, but colder temperatures have a
major impact on Saab mileage, particularly if you take shorter trips.
