Well after not sitting in the 86 drivers seat for a year Got in today to this with the car off! Never had that happen in any of my e24s. Doesnt reset either just stays on as well as “oil service “. To coincide ,after an oil change the Speedo and tach/mpg not working either. Went for ride n speedo came alive But tach/mpg not so. Temp gauge fine /gas comes alive so Ok , for now.
Fuse Okay radio comes on.
Looks like im in for a SI board
Be third one in my e24 life.
No tach

Re: No tach
Did you remove the cluster for inspection?
Perhaps the batteries have leaked.
My tach/mpg didn't work a while ago, cause was corrosion on the metal pins that connect it to the board.
But as you are having multiple issue I would also think your board is damaged.

Re: No tach
Interesting u say that. I replaced battery several months ago Never did peak inside the car to notice If thats when it started. I will make sure its not a connection issue before i remove cluster. Will b few weeks before i get back to warehouse n check but thanks
Re: No tach
Mm that sounds very familiar in my case also
After checking connections per above post I will take it on a small trip thru Paso back roads n see what develops.
As I said above speedo did come alive after brief spin .
Thanks
