    Another remap thread...or is it?

    Hi all :) I’ve decided I want to map the S3...don’t get me wrong 300bhp is quick, I just don’t like the way in which Audi have created the map it’s to smooth. It’s a very quick car it just doesn’t feel quick. I like cars that give a large amount of torque early on so you get that real shove...

    S3 Haldex, DSG & Diff oil change

    Hi all :) Do Audi stealership still change the haldex oil only and not clean the gauze filter? In terms of servicing is there such a thing as a front and rear diff on the 8v that require oil changes? Is 38k okay to wait for DSG oil change or should it be done sooner? Thanks

    Rear end fishtailing

    I was having a play yesterday when the rear end started fishtailing on a 4th gear pull at full boost from around 70mph ish.
