my car is a audi a4 cab 2004 quattro my brake pad sensor light keeps coming on not staight away from cold but with in 2 mins it comes on so had a quick look at the wires at the plug just behind the caliper gave them a wiggle and light is on all the time from cold as well ... could it be a broken wire there looks to plenty of pad left a good 7 mm easy .. or is it the connector .. anyone on this is... 90% its the front cos before when it didnt come till warm i pulled the hand break and no light but soon as break padle was pressed it came on .. any one shed any light on this ..
