REPLACEMENT FOR THE LEAKY BATTERY SI BOARD:
After a lot of research and testing we can now offer you this great multilayer PCB design.
SI or Service Indicator board is part of the Instrument cluster and responsible for monitoring temperature, mileage and other vehicle service related parameters.
It will notify you when it time to perform the next oil change, the yearly inspection, etc.
All boards have a 24h test cycle and a full 2 year warranty!
Will only fit the early E23’s, E24’s and E28’s that have the Service Interval display with 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
