ECO (Stop-Start) not engaging consistently

61 Plate 308 e-HDI Access with Stop-Start.

The eco mode does not seem to engage consistently. Sometimes (rarely) it does and the engine cuts when stopped at lights etc.

Most of the time the blue 'ECO' light in the dash display flashes when coming to a stop then goes off an the engine remains on.

Is there something i am missing with the way this is supposed to work or how to engage it? (I have taken a couple of trips where the stop start has engaged [properly every time it was supposed to.... most however it doesn't at all just flashes at me)

Any Ideas?

Ta!

Could it be because there is a heavy drain on the electrics, heater, aircon, lights etc. It was my belief that the stop/start would not operate if this was the case.

My 308 doesn't have stop/start as it's the 2.0 HDI but I remember the salesman explaining how it worked on other 308's that I tried.

Same ECO start/stop problem

Hi,

I have the same problem on a newly received Peugeot 308sw, when I stop at home or just normally park, it stops and then start the engine again within 1-2 seconds, and the ECO light flash back at me.

I have been driving all days and at least 50km every day to work, but still no change - if anyone can explain what can change it, it would be very much appreciated. I have had the car for 2 weeks now.

I'd suggest reading the owners handbook which should explain how stop/start works.

The original poster must have been satisfied with all the replies that all said the same - battery related but hasn't come back to say what it actually was - in fact his

Maybe the original poster just got tired of hearing the same - Battery shouldn't be a problem and I had a car (Lupo 3L) app. 13 years ago with start/stop technology, no problem at all, so it ain't a strange phenomenom for me - please just reply if you have something usefull, because crap about new battery's not functioning properly on a new car, ain't of any help as I see it - and just because the thread is "oldish", it seems at least for me, still to be valid.

In hope for something a little bit more usefull than the comment from storeman!

Thank you in advance.

Usually, if replies and advice given doesn't result in a resol;ution to the issue they come back and say it still doesn't work. Very occasionally someone will reply that a given solution works but that is unfortunately a rare occurence. Also when several unrelated people reply with the same answer it usually means the answer is the correct one.

Nowhere in your post did you say it was a new battery - only that it is newly received Peugeot 308sw which says you have recently took delivery of a car of unknown age in an unknown state. Besides, even new batteries will start to lose charge when under heavy load and it takes a bit of time and distance just to put back into the battery the power used to initially start the engine.

People can only respond with their replies based on the information supplied. The more information given usually results in more accurate answers. You gave the minimum information and in my opinion, got the appropriate reply.

Here is my usefull reply --R.T.F.M.

If you thought that you were missing information for making a good comment, couldn't you just ask for the information that you needed, or just not reply at all?! Instead you're acting like an ass and with no information that's usefull at all for anyone, nor anyone who'll check for this kind of problem in the future.

Again that said, please just respond if you have something usefull that you'll know about this kind of issue.

Thanks

I've given enough information TWICE now. Here is the same information for the third time - READ THE MANUAL. My 308 manual which came with a 308 without stop/start technology gives reasons why stop/start may not be available on pages 66 & 158.

If you don't have the manual (should have if the car is reasonably new as your post infers) then you can find it online here.

INFOTEC - Service Box Peugeot Easily found with a google search for 'Peugeot handbook online'

Seems like reading the handbook is too much trouble for you so it is you being the ASS and you want to be spoon fed the information.
 
#13 ·
Just as you say storeman, you keep telling the same and same shit, instead of just keeping quiet when you don't have anything useable to say - No need to tell you, but the manual has been read but needed more of an "in life" opinion, and not some dumb smart remarks, but if it'll keep you going, then just be my guest, I just don't understand if you don't have some more interesting to do, instead of posting to something that you obviously don't know anything about!

Again, again and once more for storeman AGAIN - If someone who's got more "in life" experience with this system has some VALUABLE information, then please post, otherwise just please don't...... Then I will seek more information elsewhere.
 
#17 ·
Just think you a little out of order and most forums members try to avoid using derogatory remarks and language. For what's its worth I had the same problems as you had but with daily use and longish trips the system works fine now. I found later that the my car was stored for awhile before I bought it SH but as I said it works fine now every time .. but it can be a nuisance in heavy traffic so I tend to switch it off then
 
#14 ·
Last post to you ever. You keep spouting the same old shit and I obviously know as much about the system as you do - possibly more. No dumb smart remarks from me but valid replies though plenty of dumbass gobshite replies from yourself. I have plenty of interesting things to do and have given valid responses to a loud mouth who runs his mouth off when he gets an answer he doesn't want to hear. You aren't the first and you won't be the last. Be my guest and look for an answer elsewhere.

I have given information in ALL my former replies to you (which right now feels like wasted time), except for one thing, which seems for me to very odd - EVERYTIME, I asked someone with information regarding this issue to respond, except for you "storeman", as you have brought nothing new at all, and writing "R.T.F.M" is just plain dumb and childish.

One brilliant thing that you have said just now is "last post to you ever", because now I can hope that someone who knows a little bit of the Eco Stop&Go will be the next to respond, and quite frankly I'm just at this moment happy not to hear from your childish an immature profile again, so thank you for that at least.

Looking forward for an adult to post the next reply to me on this subject, if not, then I can live with it.

You really need to give more information. Although you've said you've had the car for two weeks I cannot see anywhere how old the car is? If its new then simply return to the dealer and ask them to check it over. If second hand depending on its age then really you do need to get the battery and charging system checked over as previously suggested, these would be the key culprits for preventing the system to work correctly.

I'm not taking sides but Storeman would appear to have been genuinely trying to help. We get a lot of people who just join up to the forum and chip in mid way through a topic without any introduction and expect instant expert answers. We are a community of like minded peugeot owners who try and help each other out where ever possible however most of us would at least expect that the basics have been checked first.

Hi,

Thank you for a more polite and "trying to help" reply.

As posted before in this thread 04-09-15:
new battery's not functioning properly on a new car, ain't of any help as I see it - and just because the thread is "oldish", it seems at least for me, still to be valid.

Of course I'm just going to ask the dealer if no one knows about the issue, but as I saw this post with exactly the same headline, then i thought that someone else might have seen or heard about it.

Believe me, storeman had seen everything that I wrote, and because of that, I'm very sure that he wasn't trying to help.

Hi all. New to site, but got e-hdi with stop start and it only seems to operates when it feels all is ok with the "system". I thought it strange at first, that it wasn't working 100% of the time, but I just live with it now and realise it hasn't kicked in because obviously something needs the engine to keep running to provide power or whatever, which it refers to in handbook. I have even had it start working straight away on a journey to work but after 2 stop starts it has stopped working, how bizarre! Don't know if this helps but it is my experience with Peugeots stop start system.

Hi I have the same system..just to give you an example my stop/start system has been working ok after initially having problems like yours. I went on holiday for two weeks and when I game back the stop/start system is not working all the time. So my advise is the system will go back to normal after continued use. I read there is a booster large capacitor which aids the the stop/start and this has to be charged fully together will the battery

To promote harmony on the forum I would like to present some info regarding the working of the stop start system, this info is available to all on the web.

Quote :- Stop car & press clutch - move gear lever to neutral - release clutch - then the engine stops. The engine won't stop if the car is moving, even if the aforementioned steps are followed. The engine restarts when the clutch is pressed prior to selecting a gear to move the car. The engine may also restart if there is a demand for power from, for example, the AC system.

The system was introduced to Peugeots by the first generation 308. The alternator can reverse its polarity, switching its function to become a generator and reclaiming energy that would otherwise be lost.

It stuffs the capacitors full of electricity that the alternator then piles back into the engine and restarts combustion in just 400 milliseconds. Once the engine is warm, the alternator takes care of all restarting duties. Like Mazda’s system, the fuel savings are immediate when the engine cuts out.

Hi,

my car has the same system and i have experienced the same issues. The dealer says it´s a normal behavior because the ECO system analyses several parameters like engine temp, battery charge, electricity consumption, etc

I usual turn off the ECO because it annoys me when the ECO engages and the engine starts to shut down e restarts again. I beleave, in a medium-long term, this feature will bring mechanical issues far more expensive than the fuel saved. Of course we have to think about the environment issue but if you have to replace several parts regarding this issue it will also leave and ecologic footprint...so, let's go buy a Tesla P90D! :-D

Drive safe!

I don't quite understand, what is annoying in stop/start? You suppose to do anything special, just as usual: stop on the traffic light, put in neutral, wait, put in first, go. With or without stop/start, isn't it?
And I believe that is not reason to worry about mechanical issue, engineers do just right with technology and materials to do what suppose to do for a long time. Just like injectors, wipers, fans, pumps ....

I have experienced the same issues you describe. I do quite a lot of short journeys at the moment and the system hasn't worked in months- a long journey normally sorts this out though- for a short while. What does need further investigation is why I haven't experienced this on numerous rental cars with stop/start (including large battery sapping diesels) which have been used in similar driving conditions. I have a strong suspicion that this system is there purely to give lower average emmissions figures to comply with EU demands. The 'official' emmision figures will assume that the stop/start system is working all the time if fitted- wheras in the real world I and others find it hardly ever works (& this is important) IN PRECISELY THE DRIVING CONDITIONS STOP/START IS MEANT TO WORK IN & REDUCE EMMISSIONS! It certainly isn't a deal breaker for me as in all other aspects the car is supurb but I think Peugeot need to come clean on how effective the system is. Out of interest how are others finding Stop/Start on other Peugeot diesel models?

I got my 62 plate 308 e-hdi with stop/start a year ago, and even though I took it for a test drive the eco function never operated.

As I'd read about the system before I purchased the car I wasn't too concerned, as obviously it was cold weather in January and thought that it was quite likely that the car had been used for short test drives and sat on the forecourt etc. so the battery probably wasn't in optimal condition.

Unfortunately 1 month later the car failed to start and it ended up costing me ÂŁ200 for a new battery!

From what I remember Peugeot only give the battery 6 months warranty! and as the stop/start models require an AGM type battery I had no choice but to pay the RAC to fit a new battery.

I could have got one slightly cheaper, but it looks like a bit of a nightmare to fit, I couldn't drive the car and was concerned about resetting the system when I disconnected the battery.

The RAC did give 4 years cover on the new battery though.

So basically, don't just assume the weather is too cold etc, if you're buying a car with stop/start, then make sure the battery is ok!

My 2012 5008 eHDI seems to be doing the same.

I've not seen it execute a stop for the stop/start eco mode for months now.

It always starts, it has never even sounded reluctant to start and at rest, with no key in the ignition, the battery reads 12.4v.

So the battery appears to be good, and yet all it ever does is flash the Eco light.

Is there a procedure for resetting this function?

I've tried switching off the Eco mode and then restarting the car to see if that might kick it in, but to no avail.


Any ideas?

I have previously posted about the poor performance of the stop/start system on the new308. I have recently given my new 308 150 Bluhdi a couple of long runs of over 90 miles and it still does not engage.

I have rented several cars this year which were diesel and their stop/start systems worked fine.

The most recent rental being a Megane diesel which had only 2000km on it and a poll of recent journeys on its (excellent TomTom based and vastly easier to use than the 308's ) Satnav showed it had done nothing more than drive a few km round the airport as a staff hack and one journey Faro- Albufiera. The stop/start worked perfectly every time.

My car is booked in for its service next week and this is the main issue I want looked at under warranty. I will let you know what is diagnosed.
 
#28 ·
Thanks mate,
I'd appreciate you sharing whatever response you get.

I know it is only a minor point of operation, but I'd just like the damn thing to work as it is supposed to.

I had a test drive of a new A4 for a week this year, and it being a press car had a hard life. The stop start was impeccable and only showed just how used to it not happening I had become.

Coming back to this post after a while as i had no reolution, so just lived with it.
Recently had work done on replacing an injector after the car wouldn't start.

Now the ecomode kicks on when it should.. so im assuming that some kind of system reset was done when the injector went in? (it wasn't a feature woth having my mechanic look at before, but now it seems to work fine.)

Eco stop start on new 3008 Allure

I have just purchased a 3008 diesel blue eco 1.6 where the Eco stop start is not working. When I come to stop in traffic, I disengage the gears ie I am in neutral, and have my foot o. The foot brake the engine stops, then as soon as I apply the Electric hand brake the engine starts up again. It doesn't matter what I do, the Electric hand brake seems to override this Eco function! Is there a solution?

No, it is for security reason, so you can't forget and leave the car with not running engine and after a while engine kick in again, but without your presence. So, when your engaged hand brake, car assume that you want to go out.
