335i Heater Question

bronco · 11-09-2006, 06:47 PM

Hey all,

I wonder if you can have the heat turned on on the new 335i, without having the AC compressor work.

I hate to have my performance affected by the AC compressor if that is the case...Had a nissan 300zx and a Mercedes before, and they both had that flaw...

Thanks!

Although I don't have my bimmer yet, I haven't driven a German car that doesn't have the option to turn off the A/C compressor. I think I saw the button for it when I skimmed thru the e90 Manual.

My A/C light comes on when I engage the heater via AUTO button. I just push the A/C button to shut it off.

yeah, you can do that. But really, turning on the A/C on a 300HP car won't have any noticible effect on the power. And it's not like the A/C compressor would work really hard when you are using heat.

Plus the fact that if you turn it off, you might as well disable the auto feature altogether and set the fans to manual.
I found the climate control doesn´t work well without the compressor. If it´s turned off, the fans at times run really hard to control moisture (which is of course pretty difficult without the compressor).

A/C compressors take so little power its laughable. I forget where I saw it but someone did a dyno with it on and off and I think they lost like .8 HP or something stupid like that.
