As above, not sure how to descibe it? sort of chirping noise on slow play! it will only do it for about 1 second then stop, it does it on cold mornings when the ignition is turned to II position and when the engine is turning over to start, but if it doesnt happen in No II position then it doesnt happen when starting and if it does it on starting or not it doesnt do it at all when running.
Just to add if it does do it on possition II and I dont start the engine but turn off the ignition it will do it again when turned to position II again but not quite as much.
Jesus even i'm confused reading that back
