These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hope someone can help! My brake pad light has started to come on roughly after 15-20 mins driving. The pads are fine. Any ideas to the cause? AndyB

POST 2Original post

I would start by checking and cleaning the plugs where the sensors connect to the loom. The sensor circuit is a loop that runs from the instrument cluster, around each sensor, and back to the cluster. A break in the circuit, or if it goes to ground (ie. when the disk wears through the sensor) causes the light to come on.

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the response Richard. I'll do that. The strange thing is that it doesn't' come at first and obviously goes off when the car is next started.

POST 4Original post

Hi, I had similar problem after I changed discs and pads. Turned out to be a broken brake wear sensor lead. Once replaced with a new lead all was ok. Hope this helps. Regards ray.

POST 5 / ORIGINAL POSTEROriginal post

Thanks for the info: certainly seems as if it is a wiring issue. I drove it 70 miles today before the light suddenly came on AndyB
