I could feel my brakes need some attention soon.Ihad a slight vibration in the front when I applied the brakes. Sure enough, my brake pad wear light came on( 83,000 miles). I ran VCDS to see if it would tell me which wheel the sensor was tripping, but after a full diagnostic check, nothing on brake pads faults, only think that came up on brakes was: 00541 - Brake Boost Vacuum System P1479 - 008 - Mechanical Failure. Why doesn't the brake pad fault show up? And if there is a Brake Boost issue, it doesn't tell me what wheel. Either way, I decided to replace my front rotors, brake pads, and sensors. It was time anyways. After completing the job, my brakes are much smoother, but the brake pad warning is still on and no other braking issues like a vacuum system problem. Of course this could mean the rear wheels, why can't VCDS tell me which wheel the fault (sensor) is tripping? and or...Are the Brake Boost fault linked to the brake pads?
