I'm having the same type of issues with my'04 545. It's been very cold here(12F) so, I can make allowances for the warm up time. But as the engine comes up to temp it seems to take even longer for the heater to even remotely catch up. It seems though, that once I'm driving the temp of the heater comes up a BIT faster rather than idling to warm up the car. This is of course uncomfortable but it becomes embarrassing when the GF starts her impreza and gloats about her little "thermonuclear" powered heater.
Help?!!

Must be something about NW e60's. I'm in Tacoma.

Hi,

I've same problem (cold air from vents for about half an hour, engine not heating up to operational temp and incresed fuel consumption as result of only warm engine....) till today. The solution was replacment of both thermostats ( I'm not sure if petrol cars have two thermoststs- EGR and cooling liquid) and the diffrence is huge- 5min of drive and engine is at operational temp and warm air from vents after 3 min. Check your thermostats - 99% they bad or one of them. Heard that bad thermostats is a commom E60 problem during winter months.

I have the same problem. Before the car used to heat the car very nicely now it takes a good 15-20 min and blows cold air for the first five min. Big road trip tomorrow interesting to see how the heat will work out. Also putting the system on auto just results in cold air being blown at the feet.

I had a similar situation last year. I have a 2004 530i and I was having a similar issue with the heat. Last year my heater refused to work. When this issue started the air temp was around 10 F. I do think the colder it is the longer the car takes to heat up - something to consider. The root of my problem was the air would not warm up at all except when I'd stop at a traffic light. Only then I could feel the air starting to warm up - I mean some nice warm air, but once I was on the go again the air would get cold - it drove me crazy! I did all the normal checks and finally decided to take the car into the dealer. I was told I had a bad thermostat stuck in the open position. The repair was covered under the CPO less a $50 deduction. Once repaired the car warmed up relatively quick - well faster then my Jeep Wrangler I had :-). Honestly now I'd say the car temp is changing within 5 mins. I also let the warmup in the driveway for a few - an ingrained habit from the Wrangler. Also I never receive an error iDrive, but defiantly the signs of a bad thermostat were there. I sort of took the car for granted thinking it would let me know something was wrong, so lesson here is if you think somethings wrong and its absolute repeatable problem then take it in. I while I drive error are helpful I don't think it necessarily covers everything. Good luck!

I had the same issue car in the shop for about a month, repaired under warrenty, thermostat replaced, waterpump, replaced, and ultimatly it was the hkra system that was defective I now have heat like a mother f_cker, even out of the center console vents and it is hot not respectively cool like they say in the manual good luck on this quest for fire (heat)

what's an hkra system googled it but nothing came up

The control unit that controls the temp it maybe called something else in the e60 that is what it was call in my e34 but it had to be replaced and all is well
