messed up sid???

[bwxdme]

how good are your saab 9-3 mpg? for me highway driving i get a good 36-40 with speeds of 65+ but local driving is a whole new story i get 12-14 do you think there is something wrong with my car or is the sid broken? maybe im driving improperly , would using the shiftronic help me with better mpg? ive never driven stick so even tho this is ezier i dunno when to change gears, and is it possible to program with tech 2 to get the realtime mpg not just avg thx in advance

Sounds about right to me. On the highway the turbo is not guzzling gas as it does around town.

all depends on how heavy your foot is. are you stomping on it out from every stop? wouldnt think mpg would be that bad.

I did some stop and go Inner City city driving for a two day period last month and was at 15 mpg on the SID. To get 36-38 It's usually after I've topped off and gone immediately to highway speeds, real traffic knocks it back down to the 20's for an overall avg in a while though.

If your SID is not acting correctly it might fix itself - LOL.


My unit was not properly reporting total Mileage based on the amount of fuel in the tank. I would fill up and the SID would report 133 Miles. Finally, after about 3 months of it doing this the unit reported correctly and has been "Knock on Wood" since.

I think you're about normal. In real city driving mpg's can be pretty poor, especially if you tromp on it. It's a heavy, powerful car that happens to do well on the highway, and in town the auto eats up extra gas. The SID reports a sort of running average for the past x miles (probalby 20+ miles). You can press and hold the 'clear' button (until it beeps, I think...) to wipe out recent history, but short increments aren't that accurate, either. You can get very high or very low numbers, depending on what you've done since the reset.

To determine your real mpg, it's best to calculate it yourself at each fill up, rather than rely on the SID

I don't think it would help much in the city, especially if you're not used to shifting. On the highway, above 50 mph I usually slip it over into M5, and this helps improve highway miles. Just remember to put it back into D when you exit. Nothing really bad happens if you don't, but the trans does clunk a little and sound generally unhappy.

LOL, Heavy and Powerful are two words no-one has ever applied to a 93SS...Curb weight is 3,175 lbs and HP on a 2.0T is 210 hp. It is lighter and less powerful than a 328i or S40.

The Transmission is a Sentronic not a Shiftronic.

And The SID starts calculating/displaying mpg within seconds based on your current driving conditions.
The DTE is based on average mpg use which can change quite quickly depending on driving conditions.

The average guy with mixed daily driving gets about 300-325 miles per tank, mostly highway drivers get more, mostly city drivers get less.
