Asked by May 20, 2014 at 09:48 AM about the 2006 BMW 3 Series 325i

Question type: Maintenance & Repair

Hello, I have a 2006 325i BMW with
right at 82k miles... My first concern
is the check engine light. When I turn
my car on, the light will appear as
well as many others and then quickly
disappear once the car is entirely on,
however, when the car is in park
without the engine on the service
engine light is the only one that
appears. Is this normal or should I be
worried? I also am having concerns
about a weird whistling sound when
driving but this only happens when
the car has been sitting and goes
away after the car is being driven for
a bit. Any answers? Thanks guys!

The whistling and CEL are related. I suspect you have a vacuum leak on one of your hoses. Open the hood to see if you can pinpoint the area of the whistling and replace the cracked part. You can alsoscan for the codes to help you determine if the CEL light is on for another reason.
