Brake Pad Wear Warning on DIS

[Simon Wallwork]

Hi Folks

I put new Bosch pads in about a year ago, and all's been well.

I had an occasional hot brake, due to corroded calipers, but the car runs well now- I lubed the stainless skids with some WD40.

Nowadays though, the pad wear symbol is up on the DIS the whole time.

Today, I popped the front wheels off and checked the pads. Plenty left.

I popped the connections off and lubed up the area as it was a bit dry. Still the pad wear light is on!

I read Ians article on how to disable the warning, but can anyone suggest how to just restore it to normal operation?

Many thanks

Simon

In most cases electrical connector between car loom and brake pads wires gets corroded. Just open connector, wash with brake cleaner. Then clean the green/white oxide stuff and pry off connector a bit with a needle or smth to make better mechanical contact.

You can also order new electrical connectors from audi and change whole looms with connectors. Use Certoplast to wrap new looms.

I'd personally won't disable this beautiful feature.

Thanks Notorious

I cleaned up the connections, where the brake pad wires join the loom.

They looked OK, no verdigris or grime. But I cleaned them up anyway.

Does anyone know at which point the warning is meant to come on? ie 7mm of pad left, for example?

I'd like to highlight importance of restoring tight contact. Cleaning is not enough. Just open connector housing and make female connectors tighter.

Does that light come on with low brake fluid as well...?

Worth checking....especially if your front calipers are binding.

That's what finally made me get my calipers refurbished.

No, brake fluid level have different red warning light not amber like for pads.
