Car: ‘06 K series Built1600 converted to1800
Problem: Starting, press key fob, flashing immobiliser light goes out, turn on ignition, press starter, engine starts, but immediately stops and immobiliser light comes on.
Attempted solutions: Switch off, go through same procedure – negative. Re-arming procedure – negative. Jumping up and down with appropriate noises – negative (but feel better) Try using spare key fob – negative.
Solution which works: Disconnect battery – reconnect – go through rearming procedure i.e. press key fob (blank button) repeatedly. Engine starts – hoo-bloody-ray.
Weird bit: Once the car is warmed up, the problem disappears!
Possible way round problem: Fit Battery master switch which will make “Solution which works” easier.
Any Ideas? (realistic ones that is – renewing the entire engine management system is not!) ☹️
