Hello all,

so i was sitting in traffic and heard a loud thud in the back of the car. i thought someone had driven into me, came out to hava a look the nearest car was 5m away. looked under the car and nothing. with the nice weather i have had the roof down and everytime i go over a bump in the road i can hear a ringing noise on the rear left. after some investagative work i find out the lower part of my coil had snapped. so called audi they have quoted me £90 each. any idea where i could get it cheaper?? it an a4 cabriolet b7 s line..
