Hi. I am the very proud owner of a 2005 A3 2.0T Quattro. I am happy to say that it still drives like a dream and I am more than happy with it. I'd like to know if there are any possible replacements/upgrades to the engine I should consider as it approaches its 10th birthday. It has less than 80,000 miles, has a full audi service history. The only complaint, and its a small one is that it produces approx. 33 mpg on the open road so a little bit thirsty. Any suggestions welcomed as am happy to invest back into the car. Thanks in advance.

 

I should add that I am happy with the aesthetics of the car so I'm really looking for suggestions on any part replacements that will boost performance or increase the cars miles fuel economy. Any suggestions welcomed.

 

1. First thing would be to replace the timing belt before looking into Performance upgrade.

2. Check your Cam Follower, those things wear out fast and take the hole cam+pump with them when they break.

3. 33mpg is pretty good for the 2.0t with Quattro. I don't think that is considered "thirsty"

4. If 1+2) has been taken care of you can do pretty much anything you want at this point. There are many mods for this car. An easy one is: Cold air intake and Chip tuning (stage 1). For anything else you have to spend more money and time.
Needless to say the list just goes on.

 

Thanks Sheldon. Can you recommend a suitable air intake as a first step? Appreciate the advice btw.

 

Most of the ones that are good will cost somewhere around the 300 area. I bought the AFE but it doesn't really matter as long as you make sure it's not a short air intake, it comes with a sort of heat shield and that it has been constructed of a material that helps the air to either cool down or stay cool.
