O2 mileage counter clicking under dash behind kick panel
Posted: Apr 16, 2025 4:07 PM
I've got a 1986 staock automatic 528e.
There has been a clicking from behind the kick panel for some time now. clearly a mileage counter as it clicks slow when driving slowly and speeds up with car speed. I was under the impression that it was the O2 sensor mileage counter and the pushing the reset button on the black box under the kick panel would reset it and make the clicking stop. There are no O2 sensor lights on the overhead display, which works, or on the dash. I pushed the white reset button, and it clicked but when I drive it still makes "counter" clicking sound. I feel the clicking coming from the cylinder-shaped part to the right of the reset button. Any ideas what's happening here and how to make the thing stop clicking? Picture below for reference.
