I bought my golf a few months back, and I knew the front discs were wearing. A couple of weeks ago the pad wear indicator turned on.
Now I have changed the discs, and pads, but the light remains on, sometimes after 5 minutes of driving, sometimes after 1 minute, or just on straight away. It doesn't come on when I apply the brakes, just at a random moment, but always stays on for the duration of driving until ignition switched off.
Now a couple of questions; first one being, do you need to reset the sensors at all, or are they automatic? and how do the sensors actually work? finding this out would help me determine the problem. Would it be a circuit that is broken when the pads get to a certain level, and my circuit is broken somewhere else, sending false signals (or none at all)?
I just find it really odd, either the sensors started playing up before i changed the discs and pads, or something may have been disturbed in the process if there is no reset.
