: When highway driving on cruise control in my '81 733i, if I turn on the indicator/flashers, the car hesitates/lurches when the indicator goes on and off. Similarly, if the windscreen wipers are going, the car lurches/hesitates in synch with the wipers. It is as if any switching electrical need of the car interrupts the cruise control.
: Any ideas.

Check the batteries in your instrument pannel,
they should read 1.5 Volts each. If they do not, they probably need replacing. Both my speedometer and my cruse control malfunctioned when these went south on me. Clean all terminals and lubricate with dielectric grease. The batteries are rechargable AA type and can be had from Radio Shack if you have that chain down under; If you have trouble finding the btteries, contact me and i'll help out. Good luck, Merry Christmas and keep me posted!
