Hi all
I've had a problem with the immobiliser on my TF for about 2 months. Up until then i could leave it unlocked and when i came to start it the immobiliser would be disarmed by the fob just being next to the transponder coil around the ignition switch. Now i have to manually cancel the immobiliser alarm via the fob key each time. The fob batteries have been changed twice. Paul from Technozen suggested that this coil may be at fault. 
On a meter it reads very low resistance, I had expected it to be open circuit. Is it only possible to test by substitution? 
If I lock and unlock the car and then go to start it there doesn't seem to be a problem.

Thanks
