Warning light on 2005 vw bug

SOURCE: a dashboard warning light on

It's an orange warning indicator lamp. It lights when brake pads are weared. Now it's time to replace the used brake pads!

Hi,
You will need "VAG diagnostic software" - (google it) on a laptop and a £15 VAGCOM interface cable if you want to do it yourself.
Cheers, D.

Maybe, but the same fuse is used by other systems, and I would suspect other issues to arise, but check it out, I am wrong sometimes, hehe.
The sensor is on the bottom of the over flow. It seals in the coolant with a rubber o-ring. If this goes bad, it will leak coolant out the bottom and ruin the sensor.
The sensor pulls off with a sqeeze. Clean it with a can of electrical cleaner, and inspect for corrossion.
If either doesn't fix it, look for gremlins.
Good Luck!

Are you disengaging the parking brake all the way?
have your parking brake sensor checked.
