EGR in an '89 740? I'm not an expert by any means, but being an '89 740 GL, it came with an 8-valve, non-turbo B230F engine with either LH 2.4 or possibly Rex-Regina engine management. I see that you are in Maryland, so I will presume this car was made for the North American market. With the possible exception of a car originally sold in California, or an engine swap from a 940, I'm surprised to hear "EGR".

But check this out in the 700/900 FAQ anyway:
