Vehicle Information: Model : Cayenne S; Year: 2006; Mileage: 16000;
Took the CayenneS in with 16k miles, to have the 20k service done at dealer. Service tech says the front brakes only have 15% pad left, and recommend changing for $950. The brake sensor never came on, and one of the postings on PCA says the sensor light should come on with 30% pad left. I asked to have the sensor replaced under warranty, and dealer says their electronic diagnostic check didn't indicate any failure, so can't replace just the sensor. Does this make sense ?
