My Citroen C4 automatic is a sweet car and the automated manual transmission works superbly and smoothly. My 56-plate example is ex-Motability and has covered 19,000 miles. Recently the transmission went into 'Limp home' mode, staying in third gear. On switching off for a few moments all was well again. The main agent who sold me the car claims now to have replaced the stop light switch, but the fault has recurred. I am stuck with the main agent for another nine months of the warranty, after which I shall go back to my trustworthy Citroen Specialist, who can and does talk sense to me and welcomes my close interest.
