Question about 2002 Volkswagen Jetta TDI

My gas milage has become worse

When I bought my 2002 jetta tdi brand new I was getting 40 plus miles a gallon. Now I'm only getting 33 miles a gallon. My car is an automatic which are said to get lower gas miles then a stick shift. Any Ideas how I can fix this problem?

There are several items that can, and do, affect your mileage rating:

How long has it been since you changed your air filter?

How many miles has it been since you've done a tune-up?

Have your driving habits changed at all?

Have you checked the air pressure in your tires lately?

Have you had a geographical change in your driving routes?

All of these conditions, and a few more, do affect your mileage.

Try updating everything when you can, and see if your mileage goes up.

Even something as small as a different spark plug can do what you're experiencing.

Hope this helps you some.

When it is cool my car gets about 25 miles to the gallon. When it is hot and the AC is on it gets 33 miles to the gallon. I have changed out the thermostat. What esle could be wrong? Thank you...


Thanks for choosing FixYa and welcome. You should loose fuel milage when the A/C is on because you use more gas. Is it the other way around? Sorry for the confussion.

Why is my 2002 Chevy Cavalier horrible on gas? I am only getting 17 miles to the gallon. I have a CNG tank but no filling station close by. Could the weight of the tank be affecting my gas mileage?


Cars are just like airplanes. Weight will always have an effect on fuel milage. Check your tire inflation. We find, in our shop , that low tire inflation in the biggest cause of poor milage. (beside a lead foot like mine)

I just bought a used tdi jetta 2006 at what milage should the timing belt be replaced??? always owned trucks never had to worry about this before


I would look in the owners manual, but I would say every 90K miles. Be sure to use VW spec oil. Very important to use the correct oil.

Should a 2002 jetta tdi- automatic at 87,000 miles


That specific transmission is known for failure. Sometimes it's premature failure (in your case) and sometimes they have 150k miles, but that specific automatic transmission will always fail.
There are plenty of stories online about premature failure of the 01M VW transmission...

2007 kia rondo seems to use alot of gas


I have the same issue of low gas mileage. My 2008 Kia Rondo with V6 (2.7Lt) gets 20-21 mpg in average. Even for highway mileage, it is around 21-22mpg. Very poor gas mileage. Disappointed. I hope it would improve in the future.

Wide tires make less gas millage, get narrow wheels, let the car accomplish speed slowly from 0 to 30, look at air filter,if shortly replaced, oxygen censor, 15 miles is normal 16 miles per gallon is good for a V8

Reverse not working properly


sounds like the pump is weak, or the filter in transmission is almost stopped up. either way not enough fluid pressure to torque converter. If it was me I would have the fluid changed and a new filter installed. In all of my dealings with transmissions 80% of the time once they are messing up it is too late. sometimes when you change the fluid once it is acting up it gets worse. that is just a risk you have to take though because the outcome will be the same more than likely

Gas Consumption


If you have the RT with the 5.7 hemi as stated I do not beleive you ever got 27 to 29 miles to the gallon. the best that car will do is 24 - 25 miles to the gallon and that is on a pefectly flat and straight road at about 60 miles an hour. As fas as the MDS the best way to tell (if you can't feel it change) is to use a tool such as the dashawk that monitors the engine stats. I disabled the MDS for several reasons and really so little to no change in gas milage. I do not beleive the MDS helps as much as people would like to think. I have added a lot of mods to my hemi, but still think that 14 - 18 mpg under normal driveing is good for this car
