And, this morning the engine fault light went out on its own!

Is that normal, still shows on the start up lamp checks, so led/bulb is ok.

Sure - if the solenoids are gummed up it could well just be sticky. Take them out and give them a good squirt with carb cleaner before you think about ordering new ones. Feel like I'm repeating myself a bit here.

Its going in Friday morning for diagnostics, I have an aftermarket warranty so hoping to get new solenoids as opposed to cleaning them.

I did not know that the engine fault light could turn itself off, never known that in a car before..

Had it down to RL motors this morning, they swapped the vanos over. If the problem m oves with the solenoid then all is fine. If not it is either a problem in the timing chain setup or the vanos hubs which apparently is not that rare.
The inlet cam vanos hub is repairable, the exhaust hub is cast into the head so a damaged hub means a new head - GULP.....
So lets see what the next fault code says...

They have been swapped over and the problem has disappeared completely!
Still got a ticking on the tip of the motor, clogged up lifter I think..
