Audi a4 1.8t quattro fuel consumption

[gio]

hello everybody. I bought 1997 a4 1.8t quattro(from usa), and all i can say, it is different philosofy (i was owner of two civics). I changed turbo, fixed some minor bugs from the comp, chaged oils, timing belt, filters, but one thing that troubles me is a fuel consumtion - 15.7/19.6 mpg (city/hgw). No bad simptoms, spark plugs are ok, i even changed them, the most strange is that computer diagnosis says everything is perfect (fuel oxygen mix - perfect), no errors. guys from the cervice center here, in Georgia (caucasus), say it is normal for this car, especially the one from USA, as in USA they put in engines "larger" injectors for more power, and quattro also consumes more then regular front drive a4. Can anyone comment about differences between european and us audi-s? or if somebody had such "strange" problems, could you comment what was the reason. or may be it is realy OK?

Your car is fine it just uses a lot of gas. Thank god that we dont have as high of gas as you.

I would just upgrade the turbo and make more power for the gas consumption!

PS. More power is always good!

thanks, Adam,

now i just hope that due to high gas my car has much more power then it should. But does it? My civic even with 1.5 had more torque, hm, well may be just try to drag with an other low gas a4? I will tell about the drag results.

[Adam@mvp]

What do you mean by drag? What has been done to the motor?

i mean drag racing, to see wich will be faster, mine or an A4 wih a "normal" gas consumption.

[Adam@mvp]

I dont think that a different MPG (Mile Per Gallon) will change how "fast" the car is. Honestly should be the same unless one engince is tuned or changed differently.

So i do think also. There must be something wrong, i am sure service center guys are dummies, i am waiting for vag-com interface to diagnose the car by myself. thanks

[Adam@mvp]

Ok, let me know what you find out!

Hope that what I said helped..

This problem you're having seems to be strange to me... Out of all of the b5s that I have had, and worked with, this number does not sound right. My gas mileage on my 1999 B5 1.8t (AE quattro, 5spd, averages from 25.2 to 31.1 depending on what and where... It may deviate a couple of miles depending on oil life. I only have a cat back exhaust, and intake. BUt thats it. I have always been impressed by the fuel consumption, so your problem puzzles me... This is with 91octane shell gasoline.

I am sure there is something wrong with my car, but here in Georgia, audi service is very poor. when I was buying it, in AUDI center they tested it, told everything was fine. I bought it. couple of days driving made me sure, there was something wrong with the power. I took it to VW center, diagnosis told the turbo did not work, but to fix the problem they sent me to audi center, where audi comp guys said, there was no problem with turbo, no problem at all, concerning consumption all they told was - the ratio gas/air mix is perfect.

i took the car to a cervice with noname, they mechanicaly found out that turbo really did not work and fixed it (it is strange, but there was no valve that directs gasses to the turbo and redirects it to exhaust if the preasure is to high, so the exaust was going out not getting into the turbo at all). I did not know anything about a turbo that time.

so the only way i have to look after my car and fix it, i think, is to get a vag-com and learn from your expirineces guys.

thanks.
