Heated Wing Mirrors

nexus66 · 08-19-2005, 02:31 AM

Got out to the car this morning and it was covered in dew. I couldn't see anything in the wing mirrors, but no worries heated mirrors right?

Well, got to the station where I leave the car, and they still hadn't cleared. Now I know on my old e46 they were on whenever the engine was on, and I assume the same is true for the e90. Got out the car, and felt the mirror glass - wasn't sure if it was slightly warm or just at ambient temp, but my e46 would have been definately warm to the touch (and probably clear).

I also had the heated rear screen on as well.

Can anyone in colder climes tell me if the e90 mirrors get hot?

Have you got electric seats ?

If not I dont think you have heated mirrors

It's UK spec, so I checked to make sure, and the SE models come with heated mirrors and heated windscreen washers as standard.

I had the same problem. The heating of the mirrors now only occurs below a certain temperature. The manual actually states:

"At outside temperatures below a certain limit, both exterior mirrors are automatically heated while the engine is running or the ignition
switched on."

This is great for frosty mornings, but useless for those misty mornings here in the UK!

You are correct, I misread the system, you can get them wihout electric seats

Doh! I guess the moral of the story is to RTFM (Read The F...... Manual!)

Cheers guys

So for extra credit - what temperature activates it?

I'm not sure - I'm guessing that it's around 3 - 4 degrees, as that was the temperature and below that I noticed that they had switched on in April.

I noticed this today with my car. Dew on the mirrors and no heating.
Went to the dealer during my lunch and discovered that it is indeed temperature dependent and according to the outside temperature - they will work at 100 75 or 25 percent of full power !!.

To activate the heaters when the temperature would normally prohibit them, simply turn on the wipers and this turns the mirrors on - but if its not too cold - it will still only use part power. You only get full power if it is below 10C.

Another example of how too much complication and technology can ruin something that used to work so well - just like the indicators !! Wake up BMW and stop applying technology just for the sake of it. Often it doesn't work that well

simnew, that's the best explanation of the heated mirrors on the E90 that I've seen. Thanks! It's a question I've been asking, too.

Phila · 09-26-2006, 08:52 PM

does turning on your window defrosters turn the heated mirrors on?

E90Fleet · 09-27-2006, 05:35 AM

The values are

Without Wipers on

Temp 5 to 15'C 50% power
Temp 5 to -10'C 75% power
Temp below -10'C 100% power

With Wipers on
Temp 25 to 35'C 25% Power
Temp 15 to 25'C 50% Power
Temp 5 to 15'C 75% power
Temp 5'C and below 100% power

100% power is 18W

Question to E90Fleet.
Do you know if they have made any changes to these values with newer CIPs? My car is built in march 2005 and I had the latest CIP downloaded a couple of weeks ago and since then I have a feeling that they work faster now than in previous CIP.

They may have
They only list problem fixes and not upgrades, so its hard to know when they have updates something like this

epiphone3 · 09-27-2006, 09:03 AM

so does turning on the rain sensor count as turning on the wipers?

I find that the heated mirrors are the weak point of this car compared to older models of BMW. My dad's E30 and E46 cars defrosted the mirrors like no one's business... my E90 323i seems weak in this department (sorry to my car for speaking badly about it for the first time!)
