Had my '06 Audi A3 2.0 TDI Quattro Sport serviced and MOT'd yesterday. Knew my front pads were **very** worn (tried to change them myself but was sent the wrong parts) so asked the guy to change them aswell. Previously I hadn't had any warning lights regarding the pads being worn... Nor the rears (which were replaced a month or 2 ago). Now after the change and MOT my car's warning me that the brake pads are worn! I can clearly see the new pads are fitted correctly and have plenty of tread on them... So my question is: Can the signal cable/sensor wire be incorrectly plugged in/setup? Giving me a false positive and nothing for a true negative?
