That does sound intriguing. During the latest MOT, the emissions were raised, but passable.
I don’t want to start jumping to conclusions at the moment. And start thinking the Camshaft isn’t responding to the VVT calls.
I’ll do some basic checks on the solenoid first, and see what that brings me.
Thanks for the replies
