is it true if you open the drivers door and bonnet then turn the ignition on it aligns the throttle body? when would the best time to do this be, when engine warm or cold? also ive got a boost leak, which pipework should i generally be looking at. im mechanically minded but the 20v engine is that compact i dont know where to start. the s3 is running pretty **** at the minute and im bringing her over to england to drive to the f1 at the weekend and would like to fix it before then.
