s.i board

[jb81]

Hi all, ive not long got a 318is, the fuel guage sometimes bounces about and when you tune the heaters on to full blast the fuel guage and temp guage move up a bit, ive been told this might be the si board, is the si board the the printed circuit board that the service lights are on, behind the clocks? it would be great if anyone can give any advice on this or if anyone has had the same fault and found out how to fix it

Thanks

John
