Brake pad warning light

[jonathanc]

Hi,

I've recently upgraded my front discs to a grooved and drilled one. I've also put on a set of OEM pads. The brake fluid was fully bled and refilled as well.

However, the Brake pads warning lights came on. Can this mean faulty sensor? I don't really think its sensor though since it only came on after I changed the discs. Don't really know what's wrong unless Audi A8 doesn't like grooved/drilled discs?

Can anyone please advice?

What type of A8 do you have?

There is a common fault related to the wires leading to the pad wear sensor being streched over time and becoming faulty, documented with fix here audipages Front Brake Pad Warning Light Troubleshooting
