hey fellas, im realy interested in fixing/modding/troubleshooting my 98 1.8T a4, but im new to modding and even cars in general. i think i have the basics down(thanks to howstuffworks) and im realy confident. Is there any tips for begginers like myself? Are there any things i should know before taking apart anything?
thanks

 

also, is there a good picture or diagram and terminology of the all the parts of an a4 so i can start off of.

The first tip I have for you is to make sure you have $$ for fixing, $$ for modding, and some skill for troubleshooting. If you want to fix your car, you need to tell us whats wrong with it to get an answer on that. For modding, a chip ($500) is the best bang for the buck.. Will take you from 150hp to around 200, and lots more torque. A new Diverter valve (or in your picutre, bypass valve) will be needed with a chip (about $30) Then an exhaust($300-$900 but isnt necessary-recomended though)... With troubleshooting you might need a haynes or bentley manual.. The benley is about $70 more than haynes, but gives you about 99% more info... Its what the dealer uses. Also, most of the stuff you are looking for can be found by using the search link on top of the page. Just type in "modding" or "chips" or whatever you want to know more about.

 

Ok just tell us what you wnat to do first and we will try to help you out the best we can the best mod to start with a 1.8T would definetly be a chip then it just goes on and on from there

 

thanks for the imput

I checked my p/s Fluid and it was way below MIN. im guessing theres a leek somewhere which i cant see from the top. Where are the usual places to check? would i have to go under my car to see?
