Clio II immobiliser problem
Hi. I have read a lot of forums and seen many work arounds for immobiliser problems with Clios but not found one like this. Hopefully these symptoms will be recognised by some experienced Renault owners or technicians and a solution is already known?
With a fully charged battery, when the ignition is turned on, the immobiliser light is blinking and when the key is turned further to engage the starter, nothing happens. If however, a unhealthy battery which has around 9v charge is used when the key is turned to the ignition on stage, the immobiliser light is a solid red as it should be. Without disconnection the sick battery or turning the ignition off, connecting a healthy battery allows turning the key further to engage the starter and the car starts perfectly. This works every time, no problem. I have used this car a number of times on the weekends like this with multiple starts during the outing. I can do this quite effectively by keeping the good battery as the main battery, disconnecting the +ve cable and using a sick battery with jumper leads to the +ve cable when turning on the ignition, then connecting the +ve terminal back on to the main battery for the starting. It just looks a bit dodgy doing this in public places all the time! Any magic solutions anybody?
