750I DRIVERS SIDE "AUTO" HVAC CONTROL WON'T STAY ON
2006 BMW Other • V8 2WD Automatic • 56,000 miles
I have a 2006 BMW 750i, the "auto" drivers side HVAC control keeps turning off as i'm driving. This causes the passenger side to have to overcompensate for the system turning off on the drivers side. BMW has had the car for 3 days and cannot find "a fault". Do you have any suggestions? On a typical 45 minute ride to work, i have to press the auto button to turn it back on at least 4-6 times. I can also hear the ventilation fan, it can be fairly loud, and then there are times it seems as if it's disconnected because it makes no sound whatsoever.
The dealer cant find the problem? Seems a bit unusual. The issue must have been sent through the channels to BMW engineering as a PUMA case, does the dealer have anything about this in their communications with you? Just so I understand you, the dealer cannot duplicate the issue? And they are saying they cannot find a fault, right? I haven't a clue as to what it could be, but I also find it hard to believe that BMW engineering can't come up with the reason.
Thanks for the response! I will be picking up the car after work. Correct... They are trying to duplicate the problem, but letting the car sit and run does not "duplicate" the problem. I'm driving when it happens. I asked "what would cause the HVAC system to turn completely off by itself?" no answer! They keep saying they cannot find "a fault". I don't think this issue has been escalated beyond the staff at Wide World BMW. My feeling (and suggestion to BMW) is that the fan is not working properly (because of the noise), and it is somehow causing the system to shut down as a matter of safety or simply because it's not operating. That's a mechanical issue though, not necessarily a computerized issue that might result in a fault.
Well, the thing that I am activated by is the similarity to others in your thread. People have complained to me in the service drive about their BMW cars for problems that span the range from mild upset to total outrage, my way of being has always been to be a listening to the problem and then to take action along the lines of what I heard and then have what I heard be reflected back to the customer so that I know what direction the repairs were going to go. If that did not happen, the repair attempt almost always was doomed from the beginning. Sometimes you as the end user need to elevate the level of communication so that the issue can be heard, this can include but is in no way limited to asking for the car to be driven like you drive it, even if that means that you insist the service or shop representative go with you and you drive the car until it shows the fault. Sometimes it means going to an extreme and doing something that is out of your personal comfort zone. I do not know how you feel about screaming and yelling, I have also found tears and emotion to be sometimes effective. I suggest you see this as a process, what do you want? What are you willing to do about it? Are you willing to not allow the conversation to be driven by the nay sayers, to open your mouth and be heard? I am a stand for you to be that voice, how shall we proceed?
