I know I`m not talking Honda here but I just wanted some opinions about my diagnosis of my daughters Clio problem. Twice now with about 2 months in between each time the car has refused to start, it just turns over, and the key doesn`t unlock or lock the door remotely. The immobiliser light which normally flashes when everythings ok is on permanently. My Android phone with torque can`t read the OBDII so can`t get any codes. I`ve managed to fix it each time by disconnecting the battery, it must reset something. It will then start ok but its a bit sluggish turning over and its been working fine ever since. She mostly drives it to work about a mile away and does this four times a day (she goes home for dinner) so I`m guessing the battery is slowly losing its charge and causing the immobiliser to get its knickers in a twist. If thats the case I`ve given her a battery charger and told her to put it on charge every weekend just to keep it topped up. Also, the last time it happened I stuck my spare diesel Accord battery in, which as you may know is almost 80amps compared to the Clios 45Amps. I was told that the extra amps wouldn`t do any harm but would the alternator be able to charge it. I`ve checked out the Renault forums and this does seem to be a problem but the remedies on there don`t seem to be relevant or have worked.
