I recently changed the front disc pads on the A4, two problems.
First I broke the plug where the pad sensor plugs into on the harness end. Can I buy just the plug and splice it in or should I cut the ends off the sensor wire and splice it to the end of the harness?
Second problem, the brakes are spongy now, I didn't open up the brake lines but I'm guessing they have to be bled, or is there another issue?

Thanks
