“The AGM battery is a formidable piece of engineering that, unlike a traditional SLI battery, is designed with a high cyclic capacity and the ability to recharge extremely quickly. This is needed because, over their design life, which was projected to be around four years, they are expected to make 350,000 engine starts, compared with the 30,000 expected by an SLI battery in a non start-stop vehicle.”

 

According to the worlds largest manufacturer of AGM batteries, drivers are turning stop start off, because of this they say their AGM batteries are lasting too long, (this is the manufacture stating this not me) If drivers are being forced to spend up to 3 times the price for an AGM as the did for a Flooded lead acid battery they surely would expect the more expensive battery to last longer. My blueefficiency Merc was registered in Dec 2011, the battery is stamped Sept 2011, that makes it about 7.5 years old. I have never used stop start and have now disabled smart charging, the Merc`s battery still registers 12.7 volts after rest and starts the car first time,  as I have tried to explain, if there is little or no gain with stop/start why the need for an extra layer of complex electronics that will cause problems as the vehicle ages.

 

Again, I posted here a simple free method of defeating the stop/start system to help anyone who hates it, I was hoping to gain information relating to how the system works on your cars compared to mine, unfortunately the poster maffyou appears to believe that if the manufacture installs a system it must be advantageous for the driver or they the manufacturer would not have installed it in the first place, he/she has argued that point ever since. I don`t understand why he/she is posting on this link, I believe the title of the discussion is (Has-anyone-actually-removed-the-stop-start). I have and in good faith explained how to do it, it is simple quick and just as easily reversible, whats not to like.  Rob.

 NO that`s the whole point of this thread, if it defaulted to OFF there would be no thread.

Nope.

Not what I’ve argued at all, nowhere have I suggested that manufacturers are doing it out of the goodness of their hearts and for my personal gain.

Because winding you up is entertaining. 

 

And, as a secondary reason, I think facts are important.

According to your posts you are winding yourself up,

 

The facts I have posted are from Hyundai UK and J.D.Power, simple to check for anyone half computer literate.

 

• New to the top 10 list of problems reported in 2017 is battery failure. In fact, 44% more owners report a battery failure this year than in 2016. Batteries are the most frequently replaced component not related to normal wear and tear in 3-year-old vehicles at 6.1%—up 1.3 percentage points from 2016.                     https://www.jdpower.com/business/press-releases/2017-vehicle-dependability-study

Geeze, this is hard work, I will try again, Disconnect the small 2 wire sensor attached to the negative lead of the starter battery, stop start will then stay (yellow), to reactivate reconnect the sensor, for those with a little soldering skill, cut the data wire attached to the plug of the sensor, feed a wire into car, attach a small switch feed the return back to the sensor, insulate joint, reconnect plug into sensor, you can now connect and disconnect sensor at will without going under bonnet, this has been tried and it works, see below.

I had a bit of time on my hands this evening so I have now implemented my switch idea. I had the switch already left over from another project and some 2 core cable of the appropriate size.
I routed the 2 core to the cabin from the battery compartment using the convenient grommet just behind the battery. The sensor wiring has a red power cable connected to the positive battery terminal and a blue one which is the sensor output to the rear SAM. I’ve put the switch in the blue signal line. I’ve installed the switch in the kick panel above the pedals, so it’s in reach from the driver’s seat but out of sight.

So now with the switch closed it’s OEM behaviour and with it open stop/start and brake hold are disabled but crucially cylinder deactivation is unaffected!

Thanks Bobclive.  I will leave alone and switch off at each start up as required.  Not difficult unless I forget.  Keep calm and carry on😀

My new pre f/l 230 hasnt worked at all since ive had it

 You will forget to do this, when this happens at a busy junction and the engine hesitates unexpectedly you will then appreciate why the system should default to off. As you obviously like the system why the comment, the tread is about turning it off permanently and I have shown you how, disconnect or not it`s irrelevant to me, all I have done is shown you how to deactivate end of.

Probably because your battery is not charged to the required level, try checking it.

Don't get so hot under the collar Bobclive2.  You are quite wrong, I have not forgotten to switch it off in three years, any more than forgetting to shut the door and belt up.  If you ever get round to doing some flying, you will find there are far more checks to do before you actually fly than just using one switch.  Many of these you 'forget' at your peril.    Anyway let's hope this really is 'end of.'

Can i ask why folk would take it off?

I found it down right dangerous on my DSG, cutting engine on pulling out of junctions etc..  loved it when I had my manual before, had it disabled along with my work colleagues Audi's (who were DSG as well) using Carista..easy.

Why are people talking about turning stop start on/off? This thread is about whether it improves emissions or not, can we get back on topic please? 🙄

The thread title is 'Has anyone actually removed the stop start' suggesting the discussion is about who has or hasn't disabled it.  Not necessarily one or the other.  Please don't bicker about the direction of threads.  We often learn more when they go off topic anyway.

My bad.  There has been a fair few unnecessary digs at people of late and it has slightly degraded the good nature of what is a great source of info and entertainment.

Lets see, diesels were purchased in their millions because politicians told us they were supposedly more fuel efficient and emitted less of that dreaded CO2, actually they are nothing like as efficient as we were made to believe but do emit the far more life endangering product NOX which effects the population today. The CO2 theory goes that a doubling  of that trace gas from pre industrial levels around 1850 may increase temperatures by 1.5% C (no one actually knows if this is the case), an increase of 0.8C so far appears to have been beneficial, (world population has exploded but there is NO world shortage of food). The present  CO2 levels are about 408 PPM I believe, pre industrial is stated as 280 PPM therefor it has already taken almost 270 years to get half way to the first doubling, as CO2 is logarithmic the next doubling will have a diminishing effect on any temperature increase. The warmers say there will be a positive feedback through water vapour (the most powerful greenhouse gas), this does not seem to have occurred so far. The only danger we are in regarding CO2 is misguided politicians and money grabbing so called climate scientists trying to save the planet from a none problem hundreds of years in the future by introducing life threatening schemes such as encouraging drivers to switch from petrol to diesel cars, they have also introduced direct fuel injection in petrol cars which produces less CO2 through a slight increase in fuel economy but the deadly side effect is an increased  danger to human life NOX.

 

As explained earlier stop/start means heavier batteries, more lead content, shorter life span, more mining costs, more manufacturing costs, more shipping costs, disposing of more old batteries. A prime example in the UK of GREEN shear stupidity is the Drax power station.

@Bobclive2 dear Lord are you still going on about this, even when no one’s replying to you about it? You’ve made your views perfectly clear continuing to shout about it after everyone else has gone doesn’t make you right, it just makes you a bit deranged.

maffyou I informed you that stop/start does not improve CO2 emmissions and gave the reasons why, you then obfuscate as you obviously cannot counter those reasons, that`s what greens do. Trees absorb CO2, hardwood trees can take over a hundred years to mature, they are being cut down for drax to burn in the power station therefor cannot once cut down absorb any more CO2, Drax then burns them but for some amazing reason doesn`t count the co2 comming out of the stacks, it`s amazing what you can do in the green world. these idiots are doing the same to the Amazon rain forest, clearing thousands of acres of rain forest (the lungs of our planet) to grow bio-fuel, Don`t you understand there is NO free lunch. Shall we end it here.
