Faulty BMW E28 SI Board Instrument Cluster

BMW E28 SI Board with error.

Temp gauge should indicate the correct temp regardless of the Service Interval indicator.

this board has an error where it only starts indicating the temp after a SI reset

Thanks, I build my own test unit so I can simulate all functions and values to test these units. It's very common for the E28 instrument clusters that they fail, now I repair the.

Check out my website E28 dot NL

Very cool !! How are you able to test the e28 type board out of the car ?? I noticed the Temp needle didnt move at first, is that the problem with the board shown in the vid ?? I'd really like to know how to test one of those boards on the bench
