  2. 7 Series - E65 / E66 (2002 - 2008)
    Dear All, The A/C intercooler fan doesn’t seem to work anymore on my 740d. I tried to use ICOM and INPA/ISTA-D but it won’t move at all. Error codes I got following the clear-codes and actuation were the following ones in DDE : 41F1 4B22 I tried to use a multimeter and oscilloscope to...
  3. E46 (1999 - 2006)
    2005 325i Hey everyone -- hoping to get some advice / ideas about what might be going on with my car's head unit... I've got the BMW Business radio in my 325i and about a year ago I dealt with the broken power/volume button issue by clicking the internal button 'on' then leaving it. All was...
  4. 3 Series & 4 Series
    Hi everyone, Recently purchased a brand new 4 series (2021). About a week ago, I started noticing a strange whining noise which sounds like brakes but probably isn't. It sounds like it's coming from the inside of the car and only when the A/C is turned on. It doesn't appear all the time, but...

    I just bought a 2011 bmw 550i, the ac in the car worked fine on the drive home but when I parked it the next day didn’t work. I checked the charge and it was full, that’s problem number one. Number two my key fob won’t work. I changed the batteries in both key fobs and they will not unlock or...
  8. 7 Series - F01 / F02 / F03 / F04 (2008 - 2015)
    I just bought this 740Li 2014, less than 45K miles on it & am loving it.... however this has happened twice now.. it’s been quite hot & humid here in NY. I went out started the car, set temp at 60, max AC, to cool down before leaving, also seat coolers turned on. Let it run about 10-15...
  9. E36 (1991 - 1999)
    So my e36 has cold air and the blower fan that is located under the windshield wipers spins fast and without sound but I have almost no power at all with settings on max. Any ideas? Also I already ripped cabin filter out and no change in pressure The blower fan works because I bought a...
  10. F10 / F11 (2011 - 2016)
    Hi! Apologies in advance if this question has already been asked/answered. If so, I wasn't able to find it. My 2015 F10 is due for an a/c recharge as it doesn't cool at all anymore. The dealer said I would need to drop the car off for a few hours while they take things apart to get to the a/c...
  11. E85 / E86 Z4 (2003-2008)
    Anyone know who the original manufacturer was? Have some deer related damage and a problem with State Farm trying to sub a $60 generic Chinese unit from an E46. Just trying to figure out what makes our condenser unique to the E85/6. Guessing it’s just because it was matched to a smaller...
  12. X5 E70 (2007 - 2013)
    I have my X5 acting weird after battery went out, the ventilaton flaps are not working, in the sense that they wont move, it doesn't matter what setting I put in the controler, the flaps are just blowing to the defroster, I took the central vents out and moved the central flaps by hand (I know...
  13. General BMW Questions
    Am giving thought to selling my 78 320I. Sunroof, great paint, low mileage. BUT, A/C just quit and driver seat (original) is beginning to fray badly. Do I repair before I list? Hate to give her up but she is getting a little low for me to get in/out at my age even tho I love driving her. 2nd...
  14. E36 (1991 - 1999)
    All, first time posting in roughly 8 years (it's good to be back). This post is more to vent if anything and to see if anyone else has had this problem / bad luck. I recently replaced the a/c compressor and drier on my 1998 M3 sedan. Previously, when the A/C was turned on (compressor clutch...
  15. X1 E84 (2011 - 2015)
    Hey gang, As stated in the title, I just got my first BMW. I bought her used with 61,000 miles on her, only two previous owners - neither of whom wrecked her, and both of whom performed her regularly-scheduled maintenance - and got her for a steal, to boot. That said, I'd like to make sure I'm...
  16. E46 (1999 - 2006)
    Hi everyone! I have a 320d pre-facelift with M47 engine and my A/C Compressor making a strange whining noise when the clutch is engaged. This whining noise changes its pitch with the engine RPM and when it happens I get poor cooling too. I have changed everything except for the A/C compressor...
  17. X5 E70 (2007 - 2013)
    Since it's gotten warmer, I've recently noticed that I'm not hearing the auxiliary fan kick on.. especially at stop lights when the car isn't moving and it's like 90° outside. I tested the fan in ISTA and didn't have any problem getting it to turn on. One thing I did find was that the DME could...
  18. E46 (1999 - 2006)
    Hey guys im kinda new here but i just got my first car its a used 325i e46 (2003) everything works great with the exception that there is a mildew-y smell in my car and it is humid all the time i like to think the two problems are related and require one solution but if not i guess thats...
  19. E39 (1997 - 2003)
    Ok, so, in my epic quest to find the (somewhat elusive) cause of the TRANS. FAILSAFE PROG my e39 540i was reporting recently (now solved, thank goodness) I found that something was pulling 85mA from the battery while the car was sleeping. A bit high, I thought. So, after pulling fuses and...
  20. E60 / E61 (2004 - 2010)
    Hi Guys, i'm new to posting. so be gentle. :D i have a 06 530I blowing warm air and it just hit 100+ degrees in the car today in Florida. i grew up in Ireland so if i don't fix it soon im going to rent it out as a mobile sauna. I have a bit of a time crunch thats why i'm bringing in the big...
