This car constantly finds new ways to try my patience!
Anyway, sometimes the key fob won’t open car on first press. Then when I put the key into the ignition the steering lock comes off perfectly, but sometimes it won’t start and comes up with “ESP inoperative” message.
re-locking and unlocking the car with the fob and it’s generally fine.
I guess it’s the immobiliser not disengaging, but is it likely to be a key fob issue or something else? I have changed batteries before and the range of the key seems better, but it’s short lived.
do they need a certain battery, ie premium brand?
