Electrical System on 2009 3-series

Asked by Guru9M5XBC Jan 05, 2023 at 04:23 PM about the 2009 BMW 3 Series 328i xDrive Sedan AWD

Question type: Maintenance & Repair

When starting the car in weather that is below freezing or close to it, there
are lots of electrical system warnings and certain things -- windshield
wipers, for example -- don't consistently work.  There is a clicking sound
coming from the glove box area.  Not of this happens in warm weather.



A mechanic friend suggested that it was a problem with the fuse box and/or
electrical relay.  I took it in to a shop and they confirmed that there was
water damage in the  fuse box and the electrical system.  They were going
to try to find the source of the water and initially thought that this would
solve the problem.  Now they are saying that the whole electrical system
might be faulty (not sure why they would say that now).  Any experience with
this?  How do I work to get this taken care of?

Did your friend test the battery? When it gets colder, batteries have a tough time holding a charge. I would look at replacing the battery if the voltage is low.
