Hi and many thanks in letting me be a part of the forum. I'm in need of help and hopefully somebody can help me,
I recently purchased my 520d touring E61 it only came with one key, after having it for 3 months the central locking became intermittent until the other day it lacked up completely. I have had the key checked And that seems to be holding the charge and giving out a good signal, the locking works when using the blade but as you'll no it's a pain in the ##### when the alarm goes off!! I here the diversity antenna mentioned and the wiring in the tailgate any advice or what would be their first port of call?? Help regards mark
