On my 2004 Audi A4 the yellow brake pad wear sensor warning light is constantly illuminated on my dashboard. Brake pads have plenty of life left in them so I dont think the sensor has been triggered due to low pads.
In addition to this a red "BRAKE" warning light is illuminated when I first start the car, accompanied by the red exclamation mark (as though handbrake is applied) and a few bleeps before it goes out. This Red light will sometimes appear intermittently when driving also. I have checked my brake fluid and it seems ok.

Id be grateful for any advice. Thanks in advance for your help.
