Hi guguys replaced all 4 shocks on the S3 BAM today and had a bit of a **** day to be honest! Help required as my mate pulled on something that he shouldn't. On left hand side of engine bay between the water coolant and windscreen wash bottle there is a small 8mm ish hard black pipe that connects to some sort of round plastic thing. That's my knowledge of it does anyone know what it is and what it does? also on the drivers side front the drive shaft has a lot of play as in it moves back/forward mabe an inch form gearbox end. Any ideas why?
