'84 300D Dashboard Warning Light Question

7999 Views 4 Replies 5 Participants Last post by  ianrandom
I have an '84 300 Turbo Diesel. Love it, but I don't have an owner's manual.

I have a warning light intermittently going off on the dash. It's a circle with 6 dashed lines around it. I seem to notice that it might come on when I hit the brakes hard, and at times it will just kind of flicker off and on for no apparent reason.

Anyone know what the warning light is for, what problem I may be having and how to fix it?

Thanks, BtD

It is your brake pad warning light. Your pads are getting thin or, the sensor has a nick in the wire. Mine came on and when I looked at the pads, they were worn a bit, but the sensor wire had a nick in it and was reading off the nearest metal.

Pad warning light. Mine did similar despite new pads, no obvious problems with the sensor wires but new wires (inexpensive) sorted the problem so that was where the fault lay.
