Hi all i,m looking for a bit of advice i have a 2013 Volkswagen Passat Diesel my dads car that he's had from new done 40k and been superb until the other day he put the key in the ignition and it wouldn't start no ignition lights just says imobilser active and has a yellow steering light on the dash, he had noticed a few issues starting it the other day but by taking the key out and putting it back in again it started, Have tried a new key reader, didnt make any difference, akward as i cant get a scanner to communicate due to no ignition lights, also all of the windows went down, was able to get them back up again holding down the lock button, we do have two keys and both are the same.

Any help would be greatly appreciated Many Thanks Dan
