I have a R reg 1.8 auto estate petrol Audi A4, I would like to increase the reve's on the engine but can not find the adjusting screw to do this.
It looks like the engine is fuel injected and I am used to carb's.
Any tips were to look.

all of that is done through electronics ECU unit some call it tuning or remapping to get the best out of the car where Audi failed to do so Virtually everything is governed through sensors and electronics you will need to get a VAG tool to read the codes and know how to read them or the audi program itself and install it in a notebook so it is portable (cord can hook up to laptop & car)

good luck L8R..... carb's I know I am a 60's guy..... had to learn everything I knew over again but it is basic as yester-years.....
