Heating and Ventilation problems
X3 is about three months old and with colder weather I started to notice that there was no heat coming through into the footwell. Air con works fine.
Had car in at dealers two weeks ago to sort this out, they told me that it was now sorted. Problem is that it is not ! car is booked in tomorrow for them to re-visit the problem. Can get heat to footwell but only by turning up heat really high(23/24 C) with ambient temperature of approx 11c and using manual control buttons to concentrate heat on footwell. Very little heat with auto setting. Other problem seems to be that when driving at say 70mph I cannot get cool air to the vents in the centre console when using the rotary red/blue control above the radio, this is even with vents fully open. Only way to get cool air is to turn down temperature dial and then cabin temp. drops ! On all the other BMW's I have been able to get a mixture of warm air in cabin/footwell and cool air to the face from the central air vents ? Has anybody experienced any similar problems? I am womdering if there is a fault on the installation from the factory? With all other BMW's ventilation & air con has functioned faultlessly. |

Thankfully no issues here yet, I had to scrape ice off of the car this morning and within a few minutes driving on the road the car was toasty. Let us know the outcome of their investigations please.

Took car into dealers and asked to talk to one of the technical guys. The chief technical guy looked at it and asked me what settings I was using- to which I replied automatic as on all previous BMW's.
He said that he never uses the automatic setting and uses the manual flow controls on the LHS of the dash, reason being that the auto air con is now different on the X3.He told me that they have recently been advised by BMW that customers had been complaining about the heating & ventilation not realising it works in a different way. I pointed out that it would have been helpful to point this out at handover as the salesman said I wont need to go over the heating controls as you have had BMW's before ! He also told me that with the auto setting the flaps which control the heat and airflow do not allow them to be fully open so he uses the manual controls. To get any sort of flow on auto you need to set the auto fan setting quite high, I think there are about 6 settings which come up as ascenting bars on the display when you press the fan control. I must admit that I had this on the second setting as in the past on other BMW's this seemed top work fine and the heating automatically increased the fan speed and temperature and I never had to bother adjusting it much. Now need to spend more time fiddling with controls to get more airflow/heat, it does work but I thought the idea of climate control was that it was automatic? I was told that the new system is supposed to be more technically advanced, not sure in what respect as it does not seem to work as effectively as before-a case of ' if it ain't broke don't fix it'. Sometimes BMW technology can cause more problems than it solves. |

After six months ownership I thought I had cracked all its idiosyncrasies but it seems yet another backward step for BMW. Controlling the rate of inflow from the central vent with the fan adjustment (when this wasn’t necessary before) is counter-productive as it will presumably also affect the rate of outflow from the other air vents, and increases the general cabin noise level which in my opinion is already excessive—all in the name of ‘progress’. In the past, this was the one big differentiating feature for me with BMW in that you could get heat in the car as well as cool fresh-air to the face, which wasn't the case with most cars, and certainly a big negative with Audi. |

If you're certain that the tire pressures are correct then reinitialize the TPMS system. The correct pressures are on the driver's door jamb.
As to the turn signal error, if the dealer cannot correct it then check GA's lemon law, and start documenting everything. |

When I first got my X3 I used to have my settings on automatic and the fan on the 2nd speed setting like you did. I also didn't think it worked very well because if it was really cold or hot the fan speed never blew very hard at all. Now I just leave it on automatic and the fan speed setting maxed out and it seems to work very well. It is as if the the fan speed setting is for the max speed in automatic mode. If it is set at 2 it will never blow harder than 2 but it it is at 6 it will blow up to max speed. Now if it is really hot when I get into my X3 the fan will start out blowing at max speed and gradually slow down as the car cools, like you would expect in auto mode.

That's exactly what it is. In auto mode, the fan level is a MAXIMUM setting. That's why the fan display changes slightly. Not very intuitive... but once you realise it all the auto mode woes go away.

I realise this is an old thread, but I wondered whether anyone else was experiencing weak hot air going to the footwell area when in Auto mode?
I have the Auto blowers set to one below max so pretty high, but I still don't feel as though I can feel much air reaching the footwell! The car warms up pretty quick and I end up turning the heating down in the end as I can feel a lot of warmth from the front vents. If I select the manual downward option, then I have to turn the blower speed quite high to feel the air coming out in to the footwell. Is this normal? Seems ridiculous that I have to come out of Auto mode? Then you also lose the auto demist feature I believe. It could be that I'm use to how good my E90 is and that the air distribution is different in the way the air is released in to the footwell on the E90 compared to the X3? Or maybe it's the size of the footwell and that it takes more time to fill? Any comments welcome, just so I know whether this is the norm. Mine is a 2.0ltr diesel. Cheers |
