Hello to all, especially to CR125Honda for this thread from which I have learned quite a bit about the immobilizer. I am a novice at electronics (or should I say a complete ignoramus?) I have owned a 2002 Passat GLX wagon (170K miles) for the past year and half and have enjoyed driving it. Of late, the car starts intermittently, but curiously what I have found is that when the car won't start, everything shuts down after the key is turned to the "start" position; no starter motor whine, the instrument cluster and all electronics immediately shut off. But by chance, I discovered that all resumes back to normal if I disconnect and reconnect the battery; similar to a re-boot of a computer. My instrument cluster is original to the car (I am the 4th owner of the vehicle) and it, too, is starting to show the fading MFA display. I have only one key (switch blade type) FOB which I cannot vouch is the original key to this vehicle. I also have a Ross-Tech VAG-com analyzer which is still new to me. At this starting point what would you all suggest would be a logical way to diagnose my problem?
