if you replaced the bcm you're gonna have to take it to a dealer to
have it scanned re-learned,but only if it is a new(blank) unit-one from a
junkyard or donor car you would also need that vehicles
computer also

try hooking the original bcm back up and resetting

only thing i havent tried was replacing the bcm ..as im baffled by the no spark but i have inj pulse

crank sensor would be the main cause of a no spark i would think
but that should throw a code

Why would you spend more than the car is worth on a new engine ?

Anyhow. We needed a new key for the wife's VW
$450 at the stealership

$125 to have the computer reprogrammed to remove the anti theft by a private VW mechanic
