Had snow in my part of the UK today, so temperature this morning was below 4 degrees. Tried the Max button and it continued to work normally. Obviously as passan mentioned the compressor was probably not functioning fully due to being below 4 degrees. The green Max button LED was on and fans were on full. So its works.

IMU,
Still not sure why your residual heat function does not work. As KAF's E60 is 2004 build and mine is 2003 we can only assume the 2005 builds have it switched off.

Is that engine stopped but ignition still on?? I guess it is really, but is it ignition on 1st or 2nd position?.

I'll try it next time i'm out in the car.

I thought that if it works at all then it will work through the I-drive too, so that you can switch it on via the "independent heater" controls for first thing in the morning (before you get out of bed so that it warms the car up for you). A few members on BMWLand have it working on their X5s and E39s through the retrofit kit offered by Webasto (who also make the OEM isntallation, I believe) or have spec'd it on their order - yet I have not seen/heard of a UK E60 with it working fully (i.e. through the I-drive as well as the "REST" button)

When I look at the part for independent heater on Real.oem, it says not available for my car

The functons of the REST button which operates the residual heat system is described in the manual. AFAIK this will only work under certain conditions. There has to be a sufficient charge to the battery, a certain exterior temperature, and thirdly; the engine has to be hot.

I use it quite often. It is great when it is cold out and you need to make a quick trip somewhere. The engine has to be warm for it to work, and the ignition is off, in fact you can do it with the key out.

Just press the rest button and get out, and it will keep the interior warm. I don't know how long it lasts, however. It's good for a quick in and out, such as at the videostore. Works great with a warm V8 .

And I forgot to add.. I would guess that diesels are less than perfect with this kind of system, as they traditionally produce less excess heat - that might explain why some out there find enabling this feature hard on their car.

IMU, I think you are getting the residual heat function mixed up with the auxiliary heater. The handbook refers to the auxiliary heater ("if fitted" - !) but my early enquiries drew a blank for availability of it in the UK. I don't think that the E60 has the fuelled heater as standard like the E39 did, so even if you can get one, I think you are looking at installing the full heater, not just the remote.

IMU

Yes you're right, sorry for my moment.

Nevertheless, my REST button light doesn't come on. Does yours?

In what country did the FUEL powered, independent heater come as standard? Nunavut? The northernmost parts of Greenland?

I cannot believe it has ever been standard on any BMW vehicle. But, sure, prove me wrong

Iceman's got it? Where is he when you need him?
