Dynamic Drive

I have a 2005 BMW 645ci. The Dynamic Drive warning light pops up here & there & the car acts up. Any solutions that can be given??

Any other info? What other errors? I you get a whole bunch of random unrelated errors could be electrical, battery and/or alternator.

Have you checked your fluid? The Dynamic Drive uses the same system as your power steering, so check to make sure the fluid is not low.

If you are getting dynamic drive error with startoff assistance warning it could be SZL, the steering wheel angle sensor. If you have the codes pulled that one will show up.

Sounds like your voltage regulator is overcharging. The voltage regulator is cheap, & easy to change, after you remove the alternator.

I got the same problem - 2005 645Ci dynamic drive warning signs up a few times. Dealer said it shows alternator problem. Is it true? What if I don't replace the alternator, would there be danger? It is not cheap

Thank you,
