Please anyone can post this solution again, because I have the same problem and the link is not working.
Thanks,
Same thing happened to me ------ I changed the 15amp fuse any the indicators then flashed again when the alarm was activated.
SEE BELOW for a copy of the text from that thread :
PROBLEM FIXED
My lights are now flashing on locking/unlocking ... the problem was resolved with the help of pgl (who is a member on this forum and CERETAINLY know his stuff).
For the chappy who had the same problem as on me another thread, you need the
following:-
a 15 amp fuse(blue one)
a 20 torx screwdriver
a torch
Above the accelerator is the relay station. You cant see it when you get under because theres a cover there which has 3 screws holding it in place. Take off the cover and youll see the relay station with relays such as 53 409 etc in them. iShine the torch on top of the relay station and youll see a blue fuse ... take out the fuse. If its blown then this will fix your problem for sure. Replace the fuse and cover and your done
