Hello all, I'm a new member hailing from Montreal, Canada.
I own a 1999 A4 1.8T with 220,000 km (135,000 miles). Love the car, it still drives and looks great. It was very reliable until it reached 160,000 km. I think I've spent about $15,000 (Cdn) on it since then to fix a variety of problems. Perhaps someone can help me with my latest since even my mechanic isn't certain what should be done to resolve this.
My breaks seem to pump almost every time I apply pressure on them, however it's not at the same pace as when the ABS activate. The rate of vibration is much slower and louder. I've changed the pads and rotors. Had the rotors re-surfaced, the sensors cleaned, and hooked up the diagnostic tools on them while driving and found nothing wrong. My ABS light does not go on, however, we tried unplugging the ABS unit and the problem disappeared. Can anyone help? Is it the ABS unit, the ABS sensor or perhaps something else?
Any info would be greatly appreciated.
