hi im new to the tt ive only had it about a month but i seem to have a problem.my car drives fine and with no problems when driving normal or just the odd squirt of the pedal BUT today i was having a play with my mate in his cupra r up and down the local carraige way and after a couple of minuits of hard driving i had a horrible knocking/vibrating noise coming right through the car it felt like it was from front to back i got a bit scared so i slowed down to about 30 for a bit then it went so i put my foot down again around the island and the as i was going up through the gears it started again.it seems to happen after ive gone round a bent a bit up turning slightly when going hard at it.any help would be greatly appreciated thanks guys
