Welcome to the forum. welcometomyturbodies

These immobilizers can be a pain in the a**e. My http://www.myturbodiesel.com/forum/f4/passat-immobilizer-4472/.

I'm don't know what you mean by battery light? Are you refering to the generator light?

That is strange. Is the battery defective? Use a voltmeter to check the battery voltage around 11.8 and generator w/engine running, around 14. The immobilizer normally resets if you leave the car on for a half hour or so with the key ig nition.
