i have a 1997 528i and recently when i attempt to engage the cruise control i occasionally get a surge, as if i just floored the accelerator. it doesnt happen all the time, occasionally it works fine. i've had my mechanic reset the computer several times but it has not fixed the problem. my mechanic also gets no error code. it shows up as everything is fine. he has the computer specific for bmw's so i know the comp reading, of nothing wrong is accurate. anyone else ever expierence this or hear of this and any solutions? thanks, rob marsh
