Thank you for your reply. No sluggish starts here in the mornings when I do have to go our early and we never get it very cold in winter so that wouldn't be a contributing factor. I'll have a word with the garagiste on tuesday when it goes for its contrĂ´le and service and see what he says. It was the thought of having to pay out for a new one right at this time that was worrying as the big utility bills have just come in.
