#s3

Okay so I have a 2017 Facelift S3 Sportback, as pictured <------------------ I have noticed when I push it hard into corners I get the back end coming around. I read alot before buying and heard that if anything the S3 understeers which is the opposite to what I am getting. I was on my way...

A quick question.... I have a Audi s3 02 bam 225 my turbo oil in feed keeps leaking oil at the turbo side, I have changed the washers 3 times now every time with washers from Audi and can't stop it leaking?? I'm baffled, am I over tightening the banjo bolt?? Is there a certain torque that it is...
