Hi Steve,
Thanks for responding. Yeah it's electric steering. The battery is at least 4.5 years old and could well be older than that. bBoth myself and my mechanic tested the battery and although it didn't give sterling results (I cant remember voltage reading off the top of my head) it was in a reasonable condition. I'd have though a dashboard warning light would show at the very least if it was battery related. Regardless of whether it is the battery or not I feel it will shortly be time to replace it anyway so maybe when I do change it out the problem will go away. Thanks for your input, much appreciated.
