Hello,

Have been looking at on line prior to my car being delivered tomorrow.

What if any are the prose & cons of stop start setting. Does this drain the battery or wear the starter motor ?

The idea of constantly having to start a car throughout any given journey seems very odd.

I cannot see why Auto Hold setting should not be on permanently, am I missing something ?

Thanks. 

 

Enjoy the new car.

 

You do not have to start the car as such other than when setting off, the stop / start system designed for the vehicle does the starting very easily as you touch the accelerator, turn the wheel etc after it has functioned.

 

Some do not like 'Autohold', so the choice is there to enable, same as the choice to disable Stop / Start. 

So many choices, and the change to do what suits you, and maybe on different trips in different weather you might do one setting and on another do something else.

Or another driver might set as they want in the same car.

I love the autohold facility on my Superb, however when manoeuvring into parking places etc I turn it off. 

 

This is because It makes “creeping forward” a bit jerky - you stop, and want to move another couple of inches and by the time you’ve overcome the resistance of the autohold you have to jump back on the brakes sharpish to avoid over shooting where you want to be. And so on.

 

You just have to remember to put it on again before turning off, if not the car moves a bit...a bit scary the first time it does it!

 

Mine is a DSG and maybe you don’t get the same issues in a manual?

Touching the brake pedal lightly and braking does not put on 'autohold' you need to press harder for that.

Same here. Same reason and usage.

There is no real benefit to the end user with this technology. It is best to disable it. Only premature starter and battery wear will come of it.

There is every reason for it is you are stationary in traffic in built up or not built up areas and vehicles are all pumping out emissions with engines running.

Once Australia gets real on emissions and maybe stops mining the coal to fuel the world (& the minerals for the EV Batteries)  the mind set will change.

Having a car with auto hold basic, ie a 2015 Polo 6MT without the ability to switch it off - and it being "short term hold" and a car with full Hillhold with an on/off switch, I'd pick the one with the switch - and the proper Hillhold, as it gives me the option to use it under certain driving conditions and to disable under other driving conditions. I don't like the feeling of easing the clutch out and sensing the car initially fighting the brakes as they slowly come off.

 

Stop/Start is here to stay for obvious reasons if you drive in inner cities, some people still seems to think that it is a cunning plan by VW Group to keep raiding your wallet, it is due to changing ideas about inner city pollution due to too many people wanting to drive their cars where only buses/trams/trains/tubes should be running - as far as humanly possible I try to avoid driving in inner cities, there are usually smelly buses available for the final few miles, keeping away from inner cities is also a good idea as humanity has morphed a bit in there??

Speciousness reasoning unless you drive an electric car. Come on. Idle fuel consumption is so small compared to actually moving those 1500 kg

 

Go look at the raw data before making emotive arguments like this. Idle pollution is not the issue here.

Nothing to do with fuel saving.

To do with 10 miles in and out a city and it taking an hour, and no need to have the engine ticking over for all that time stationary.

Then what does it have to do with?

Cutting down on emissions as has been stated previously.

Fuel savings and emissions are the same thing.

 

Idle emissions (5%) are not the problem. Emissions while moving are (95%).

 

As I said, do the math.

 

You want to argue about this stuff, start driving a hybrid or electric car.

 

And what if you want air conditioning?

Edited 12 June, 20197 yr by digifish

@digifish

Are you on a wind up?

 

Air Conditioning!, more like Flying Jackets and ear warmers needed. 

Global Warming not so much an issue, just Climate Change.

 

Pollution / emissions, Glasgow, Edinburgh, Aberdeen, Perth, Inverness, Dundee, Creiff, just anyplace with gridlock or traffic at standstill. 

& Scotlands aim to reduce pollution which yesterday they admitted they missed for a second year.

Today the UK is making new claims on pollution reductions by 2050. Zero.....

 

PS

I ride an Electric Bike and park and ride. 

Sadly the EV's are delayed currently as the Elephant in the room is Australia & other mineral rich countries not getting the batteries manufactured quick enough.

More Renewable Solar Energy Production needed and pull the finger out required.

Thanks everyone, comments all noted.

Mine is the DSG , I can see how the Autohold might be a bit awkward when manoeuvring , parking in tight places etc, so I will certainly take the advice to turn it off when performing manoeuvres in tight places. The rest of the time I think I will leave it switched on. 

The stop / start I will have to see how it goes , I can see the obvious issues & benefits re pollution in city driving, but in general driving conditions when you stop at traffic lights in urban settings or roundabouts in similar locations it might be bit ‘over the top’. 

Thanks again everyone, no doubt loads more questions when car arrives tomorrow lunchtime. 

LOL,

Or just don't press the brake hard and Autohold will not come on.

Not at all. I have a science degree and like to look at the data.

 

The facts are. There is little correlation with congestion and emissions. Full stop.

 

When 95% of the emissions come from moving vehicles then stopping 5% is irrelevant.

 

Idling emissions are not your problem. Vehicles moving and using fuel are. No?

 

Lets flip this problem. You realize that cars on the freeway are creating more emissions than those tootling through a village?

 

What matters is not whether a car is moving or stopped, but how much fuel it is consuming per-hour. And moving cars use (on average) 19x more fuel per hour than idling ones.

I'm not too sure that I was arguing.

You obviously know far more about this topic so I'll leave you to interact with the other participants. 

@digifish

With the greatest respect your Science Degree appears to not have helped you get to grips with 'Autohold'.

 

Tootling through a village you are moving or you are stopped.

One of Scotlands highest emissions areas is seemingly on Crieff High Street where a few hundred yards of high buildings is trapping the emissions, 

a by-pass would be the answer there and really the readings /figures are a bit sus, probably done by someone with a Science Degree, all the gear and a bit of an idea.

The council are planning on banning idling on Crieff High Street, quite sensible really.

Other high emission areas happen to be near the Bus Stations and Taxi Ranks.  Banning keeping diesel engines and inside vehicles is sensible, 

but hats, coats and gloves required for drivers much of the year.

 

 

 

 

It must Just be something that came about to boost the sales of expensive batteries and engines / components.

Wasting the worlds resources and boosting corporate profits.

Come on again. Yes you are wasting fuel idling. However, you are wasting SO LITTLE compared to moving. You are wasting 5% of the fuel you use compared to moving. 

 

Look at the numbers, forget the words. Seems like you have been sucked into an emotive rather than data driven argument.

 

You can save more fuel (i.e reduce emissions) than you waste idling simply by driving with a less heavy foot. Better yet work from home.

While I question your numbers, it's painfully obvious you use more fuel when driving isn't it?

 

Yet every little helps.

@digifish

Over 40,000 miles with a 2.0TDI SCR / DSG i do the same or similar trips passing through the same cities if i head south or north.

I have used Stop / Start, and had Coasting Function Enabled and tried also without Stop / Start & Coasting, so know when i can get 630 miles from 63 litres of diesel or 730 miles.

 

Same average speed journeys pretty much as Average Speed Cameras cover a few hundred miles of the trips.

So basically i know what is what MPG wise, weather wise and getting through cities in rush hour and gridlock or flowing traffic.

It is not rocket science it is driving and paying for your own fuel and knowing what every vehicle you might drive or ride does in the way of economy.

 

PS 

Love the work from home bit,

you sound like a Politician or something, someone that thinks everyone can do that. I could actually, i gave up work.

Do you work from home and with what you earn then stay at home and look at the science of the world & out the window at your car?

Try going out and driving, and try a brim to brim of your car, try some parking with Autohold enabled, reversing up slopes and easy on the brake,

and if you are not doing stop / start journeys then Stop / Start enabled will not concern you.

This problem is not solved by little solutions. Urban air quality will only be improved when people stop driving ICE cars there.

 

Start-stop is 95% BS and will never make a difference to pollution for that very reason.  

 

 

@digifish There you go then, you never wasted your study time.

It will never affect you then if people use Stop / Start or not.  So what's the wuckin furry?

Because (we) consumers have to pay for it at purchase, and then in more expensive battery replacements and any other associated issues with the extra complexity of the system.

 

And, in the end its not the solution to any problem we face as inhabitants of the city or drivers.
