Dave, I cannot claim to be able to answer questions on your presentation but am pleased to know all of the things mentioned are working correctly in my car.
On the second topic of your future motoring, I was rather hoping you would go for an Aero next, lovely big V8 and a lot of gears. This for selfish reasons, in that you are prone to taking things apart and explaining them on this forum. Less adventurous souls, like myself, can then benefit from your pioneering spirit.
Dave
