Hi John That's clearer for colour and I can see what you mean, not bad to get a gas sniffer on the car if you have a chance, even if its at the MOT as you don't want to go too low as that can be expensive. I am always suspect when something has been changed and sometimes after a fault shows up. You would not believe the number of customers who would arrive at the garage with a fault and then in the conversation would drop in 'Oh, I changed the XYZ 3 weeks ago'.....its amazing how things are connected, cause and effect and all that.
Good luck with solving it, you will get there.
