Looking to replace my pads here soon and have noticed that for my 2000 a4 avant there are three size listings, determined by whether the are has Large Round Wear sensors or Oval Wear Sensors or no sensors..what would help me determain which settup my car has? Or does it not matter? from what I can tell the difference appears to be pad thickness.

2.8 manual
hawk pads

Thanks.

GRC.
