BMW E60 535D Electrical problem

    I have a 535D 2005 which has an intermittent electrical problem. Shortly after starting the car the electrical power seems to cut out for a second and every error message under the sun comes up on the idrive. battery fault, servotronic failure, abs failure etc etc. If you switch off and restart its fine then all day. Generally happens about 3 or 4 mins after you start the car.

    So far have had a new battery fitted and coded correctly, new IBS battery lead, New MPM module. Now running out of ideas and money.

    Anyone ever heard of this before or any ideas on what to check next. A few US BMW forums have shown the same issues with cars there but there were no posts on what actually causes it.

    I don't think anyone's going to have the answer here. I'm guessing it's had time to sit on a BMW GT1 or the newer ISIS diagnostic machine?

    The only thing that shows up on a diagnostic check is low voltage so we changed battery and MPM module. Alternator seems ok and charging voltages are fine. At €800 I am holding off changing it!

    Have a look on bimmerforums.com and bmw-driver.net for a start.

    Got it sorted at last. The regulator in the alternator was faulty and was causing electrical spikes which were knocking out the electronics intermittently. Thanks for the help.

    @ Are we nearly there yet.... I think I have exactly the same issue. Can you tell me what sort of cost was it to replace the alternator regulator?
