Replacement for the leaky battery Si board:
After a lot of research and testing we designed a great multilayer PCB with a batteryless design.
All boards have a 24h test cycle and a full 2 year warranty!
Because of the batteryless design, the Service Interval function is deleted.
The rest of the instrument cluster will be fully functional.
Will fit all early E23’s, E24’s and E28’s with the early cluster that you can recognize for having 3 red LED’s instead off the later one that has only 1 red LED.
Does not work with Early (PRE 1981) E23’s and E24’s
