If ya read my post a while back (this thread I think), I mention how great the air cond. was in both our E53s, and the air in my 05' M3 and both E46 330cics was excellent. The air cond in our Z8 Alpina is great too. It's just newer BMWs, that the air seems very subpar. It's awesome if some of you have great air...you're lucky :)

Since 2004, my Spouse and I have bought 9 new BMWs. Besides from the 2006 E90, 2007 E70 and 2008 E70...they have all been nearly flawless, performed beautifully and given a lot of pleasure. In a way the 2006 E90 and 2007 E70 were somewhat "my fault", as I know better not to buy a first model year. This is not unique to BMW, but true for most makes (especially German and American). I honestly just thought the 2008 E70 would have none of the problems and glitches that the 2007 models had. I am in awe of BMW's safety, engineering and overall quality...but I honestly think they have become somewhat "cocky", and got used to MBZ having such problems for 5+ years, while BMW didn't have any, or much negative press in terms of reliability problems (although the 2003/2004 7 Series was a nightmare!!). BMW is just taking their sales somewhat for granted, IMO of course. I will always defend BMW in terms of safety, as they are amazingly safe & solid vehicles!!

I just went to the dealer to complain about A/C, in my case it often stops blowing cold air while the car is not in motion. :dunno:

And they indeed found a faulty relay which turns on/off the fan. They replaced it and everything is cool again :wow:

air con plus towing SUCKS!!
 

I have posted this problem separately here:

I would appreciate if you guys read and tell whether experienced the same problem and how to solve it.

In short, while a trailer electric outlet is attached (regardless what trailer), the air con goes off and comes back only when the plug is taken out.

Please help, soon I will be cooked tender in the E70

BMW guys have no clue what the heck is going on.

Is this a factory hitch? If it is, you leave it with the delaer and tell him you will pick it up when he figures it out. If they give you any trouble, call BMW directly. From my experience the problem will be solved immediatly.

If this is not a factory hitch, you are on your own.

I cannot think of anything else, as I have tried 2 different trailers and the same thing happened with both - so I can disclose the trailer electical failure related issue. Seems like a factory hitch.

thx for the advice anyways....

I wonder if anyone else had this same thing.

Just to follow up. Took it back to our dealer this morning. My wife was told that there wasn't a problem with the a/c. She pitched a fit and then learned that the unit was cooling on the driver's side, but not on the passenger's side and the rear unit. We learned it may be in for a couple days and they gave us an X3 loaner. I'm a little miffed as I was skeptical of this a/c upon delivery and was told it was because it was brand new.

WHAT???? "because it was brand new"

BTW- For those with AC problems, are you aware that the AUTO button is 3 phase? When you push it once it is low air flow, 2nd time is medium and 3rd time is high.

can anyone tell me why may A/C blows cold out of my left side vents but not the right side or the rear ones in my 01 X5

Just to update. The E70 air conditioner as designed works GREAT (in our loaner). Unfortunately looks like I have a problem and it's still being sorted out.
