Does your E23, E24, or E28 instrument cluster show service interval (SI) lights in an illogical combination of green, yellow and red LED’s? Does your tachometer make noise? Coolant gauge inoperative? Speedometer broken or keeps blowing the fuse? Economy gauge not working? If so then you most likely need to replace all of the capacitors in your instrument cluster.
ATTENTION: Your SI board must be in good shape and not heavily corroded due to leaking batteries!
First off you need to determine which cluster board you have. The easiest way is by counting the RED number of LED’s:
3 RED LED’s in the line of 5 green and 1 yellow mean you have an early type 1 cluster, see picture gallery.
1 RED LED in the line of 5 green and 1 yellow means you have a late type 2 cluster, see picture gallery.
Once you know what type of cluster you have simply select your variant below.
NOTE: This requires knowledge of electrical components and the ability to de-solder and solder components on a printed circuit board!
