Don`t think you have immobiliser problems but would make sure all your filters/plugs are clean and in good condition and may need plugged into a computer/code reader to see what fault codes are there and one more thing, do you realise the problems owners have with their Renaults? Just on this forum there are thousands of problems registered, mainly electrical issues, if there is one manufacturer I would steer clear of it is this one and French cars in general, good luck with your Clio, think you will need it.
