E12, E28, E34, E39, E60General discussion and technical help for all year 5 series cars.
I put together a little information on the cruise control servos used in E34's and other BMW's. Included are some pictures and diagrams. Here is where you can download the pdf Cruise control actuator - Technical information
This is still in draft. I've include a few pictures showing how to remove the actuator from a 540i without tearing apart the headlight and grill. Please let me know what you think, (i.e. what's missing? mistakes? what should I do to make it better? etc.) On the other hand, maybe not so many care about the internals of these devices (they just happened to catch my fancy...)
