Ordered some relays for my 2005 z4 GM5 module ( tyco V23084-C2001-A303 )Same as I ordered for my 2003 z4 a few years ago. Only to find it has different relays in it. ( NEC EP2F-B3G1S ). Fantastic. Just assumed they would be the same.
You need a very good soldering iron to remove them or a decent de-solder gun. It's easy to damage the tracks. We use £750 induction irons here at work and it's even tricky with those.
