This is veird. It's electric, doesn't run on coolant. As we've discussed the increased electrical load on the alternator should in turn load the engine more speeding warm up time. Which is probably why it's programmed that way. 3 Link to comment Share on other sites More sharing options...

Stoney871 Posted January 13, 2017 Share Posted January 13, 2017 Remember that the rear demist circuit also operates the external mirror heating coils too. It's a safety option to ensure clear all round vision that is required for safe driving in cold conditions. It also helps to remove water from external mirrors in wet driving conditions. 1 Link to comment Share on other sites More sharing options...
dzincha Posted January 13, 2017 Author Share Posted January 13, 2017 Why they make start/stop system and led for lights? To save fuel and watts(led)? But then turns on auto window heating and all savings go to waste. In vw case if i order heated windscreen they add generator with more Amps. 80A if i remember correct. How many Amps screen heating consumes? Link to comment Share on other sites More sharing options...

VW don't need to worry about emissions as they write better maps than Ford. 2 Link to comment Share on other sites More sharing options...

Normally it is just wet and wiping is fully enough. Then question is - why those 2 buttons are on climate control? Outside mirrors are also on same fuse with rear window heater? Yeah vw made big ***** with co2. It is nonsense, because every car delivers at least 40 g co2 more in real tests than it is written in specs Link to comment Share on other sites More sharing options...
dzincha Posted January 13, 2017 Author Share Posted January 13, 2017 Just tested one thing : Started up, drove few km, stopped at red. Start stop is grey. Motor t ~60 degrees, switched both windows on, then off. And guess what? It switched off engine via startstop system. So on off and screens are off. But isn't this stupid? Most winter is just plus 2 -5. Below minus not so often. So mainly it is just wet. And why it should warm it up? To make some tea? If u need better view, wipe off wet stuff and it is ok. And i normally drive forward, don't really care about rear window. And in winter with - deg it is mainly snow there, it takes longer to heat it up than just wipe it off. Maybe in Spain when it is coming to 0, it is catastrophic and all heaters should turn on. Here it is half year with that weather. Link to comment Share on other sites More sharing options...

Ok, generator compensates el.heating consumption. Nowadays i got vw golf6. During summer i thought that it is time to check how full/empty battery is. I puted charger(5a max). So it started with 3a and during 24h it dropped to 2a and didn't went to 0 as it should do. Then on one summer sunday we should go to festival and i could't open the car with remote. Opened with keys and starter gave 0 reaction. battery was flat. Later during several service visits they found vampire- alarm buzzer. It sometimes activated itself and beeped How long it takes to get fog or ice away from front window? Today got humid air with rain/snow and screen was foggy. 2mins for fog and ice could be even 5. Could be faster. Link to comment Share on other sites More sharing options...

Strange that it is not mentioned in the manual. I did wonder a bit why it came on by itself. I have had my car for a year now and just seeing that. I think I have seen it earlier without the parking heater. Link to comment Share on other sites More sharing options...

dzincha Posted January 14, 2017 Author Share Posted January 14, 2017 When both heaters on - consumption 0.7-0.8 l/h, when off 0.4-0.5 l/h. Is it heating all time or only when engine is cold? If engine is warm they goes off? Is there thermistor for regulating on off cycles or it is just on all time when it is below 4 deg. If they wanted to heat up engine faster, then put some heater in engine in oil colector or in coolant pathway for getting hot air faster. Ok this is easier - few clicks eith mouse in controller sw and windscreens being warmed up with load on engine and generator. After years generator will get problems faster than without this auto feature. Link to comment Share on other sites More sharing options...
alexp999 Posted January 14, 2017 Share Posted January 14, 2017 Don't I know if it relates to engine temp. But it's only on for 5-10 mins the same as when you push the button yourself then whatever causes it to go off. Link to comment Share on other sites More sharing options...

Or run the coolant past the hot EGR and turbo, shut off the intercooler and fit a small electric heater in the HVAC box... There are already methods in place for heating the engine to operating temp quicker. Can't you switch off this function using Foccccccccus or something if it bothers you that much lol? I have the option on the Mk2.5 to enable 'auto heated windows' but it wasn't activated from the factory. Like you I'm ok with just pressing the button when necessary, my rear window rarely steams up unless I get in with wet clothes but the front needs demisting nearly every time I go out this time of year.

I've got a mk 2.5 too and wondered about that as mine isn't auto at all. I used to have a mk3 Mondeo TDCi LX and that was surprisingly well kitted out for poverty spec. That had (IIRC) auto 'chaos' which switched on everything to do with front and rear windows. Air direction was via buttons so screen air only was activated along with A/C, heated front and rear, max heat and full fan speed. Or was that a 'chaos' button and just front and rear heat was auto...? Link to comment Share on other sites More sharing options...
TomsFocus Posted January 15, 2017 Share Posted January 15, 2017 Hmm, not sure about auto chaos, Dad has had a couple of mk3 Mondeos but I really can't remember. If you've got ELMConfig you can activate auto screens easily. 1 Link to comment Share on other sites More sharing options...
