GT1 is usually used for the latest batch of cars like E60, E65 and E90.  Basically there is nothing to overhaul with a valvebody, basically some springs and small little pistons (if I may call it). What is usually done, is to clean it properly (all the fluid chambers) and ensure the springs are still working effectively.  And the usual suspects are the solenoids. The modic 2 itself can show which solenoids is/are faulty. If got no modic, then use the old way....connect a 12V battery directly to each solenoid and try to hear the ticking/clicking sound, if there is any sound then its ok.</blockquote>
