Rear Windscreen Heater
I have a 2017 440i GC and I have just used the rear screen heater...and it is painfully slow...just started to clear after 15minutes. Anyone else noticed this or does it need to go back?

It's fine, it will be quicker clearing ice. It takes a lot longer to clear condensation, mine takes around 20 mins this time of year.

Cars are damp at night now along with the windows and mirrors. Maybe it's warmer in Norfolk?

What's causing it? Not using A/C to dehumidify? Or water ingress? |

its the condensation on the outside of the car, just a couple of mornings there has been some on the car. My old x6 cleared it within 5 mins.

Doesn't normally mist at night. The typical situation I have cars that mist, is when the temperature drops fast mid afternoon, on sunny winter season days. Caused by damp in the car, like damp carpet mats. Then it is usually the front screen that starts to mist first, from the bottom. If I see that happen, I get the driver's mat out when I get an opportunity, and dry it.
I use A/C all the time, so keep humidity in check. I see lots of cars up here with very misted windows. I wager most is caused by damp, either through use, (wet clothes, shoes, etc.,) or ingress of water, and/or not using A/C to dehumidify. |

I wouldn't be surprised if BMW are cutting back on element output to help eco credentials. We'd need to check out the wattage, see if it is so. |
