I've got a 2001 (Y reg) Clio II, and it's developed what I think is an immobiliser problem.
When I unlock the car and try the ignition the immobiliser light on the dash-board flashes quickly, indicating (according to the driver's handbook) that the immobiliser hasn't been deactivated. Sure enough, if I bother to try to turn her over, she coughs and dies immediately.
However, if I sit there and use the key-remote to lock and then unlock the car, then try it again, it'll work, probably 5% of the time. It took me 8 minutes of trying this morning to start the motor to get to work.
This originally happened about 2 years ago, with the other key I've got, but I switched to the spare key, and it worked fine, no problems up 'til now. (I recognise I'm a Bad Lad for not getting the original key sussed out at the time - I thought it was just a fault with that key).
I've searched on the internet, and on this site, and it doesn't sound like (to my very inexperienced ear) the
Sensor problem - at least I haven't seen anyone else mention that trying different car-keys made any difference at any point, and no-one else has mentioned the dashboard light flashing to indocate a problem.
I've rung up my local Renault dealership (Reg Vardy, Sheffield), and they want to book it in for a diagnostic which is going to cost me £65+vat just to find out what's wrong with it.
Anyone got any suggestions? I hate giving money to Vardy's, after the way they conned my wife when she originally bought the motor.
