Just installed a newer General module

[Bill R.]

can use and which ones you can't use? The central locking component changed after 90 and the module for each is different. They have an updated module for the early cars and an updated module for the later cars.

I just installed a newer General Module from a 1995 525i into my 04/1989 build 535i. It took care of my irritating lock/unlock twice routine, made the rest of the windows one-touch down (only), and a few of those other cool things the newer GM does. Shogun has posted several times in the past about the newer GM's so I have been on a search for the newest one I could find. Thanks Shogun...no denying you are a GURU!

Oh, the newer GM P/N I used was 61.35-8 355 818, the one that came out was 61.35-1 379 740.

Bill, if you have such info in detail, that would be fine. I am often asked if someone can use any GM in any built year, but I do not have such info.

Now I have a GM from an E32 750iL made in 03/1994, the last month of E32 production. Not yet used, still in the car I bought last year.
And I got another one together with the RM from a 1993 E32 740iL.
