Just had a similar scenario with mine - reading 51 advance (I think) at idle. It turned out to be a piece of swarf / metal stuck in the valve which I extracted with a screw driver - now works perfectly!

If the coil fails in the OCV then they tend to get stuck at 0 advance (which means they need replacing) but if stuck at anything over 0 advance the valve probably has something jamming it open.

If they are not jammed you can move the valve easily with a screwdriver against the spring and then when you remove the screwdriver it springs back to shut again.
