Flashing IMMO light :/ Please help!!!!

[Jock3]

Hi guys, I tried to program a new key for my Golf mk4(-99) yesterday using a VAG tacho Opel Immo 3.01 cable, following Ohsnap´s great guide on this forum. The problem now is that even though both keys (1 old and 1 new) works and starts the car and I´m being able to drive and so on the immobilizer dash light keeps flashing, the only thing i can think of that I missed in the procedure is that i didn´t choose to "delete old keys" in VAG tacho...so the question remains that if I try to program both keys again, checking the "delete old keys" box and enter a value of total 2 new keys, will this work, does anybody have any experience of this problem? Any help would be greatly appreciated Have a good one /Jock3
