Car has covered 8k and is 4 years old. Stop/start has not kicked in over the 500 miles I’ve driven so far. I did see low voltage warning on the dash once but plugged into ctek for 48 hrs on recon mode and not seen that warning again. Everything else works fine, just no stop start. Is this likely due to battery being too low. I can find a message on dash that says ‘power consumption is high’
-
I think this is caused by the battery, I changed my battery over the winter and had noticed the same thing as you. Once I changed the Stop/Start continued working again
-
At 4 years old if it's the original battery then chances are the battery is on its way out. When I bought my car it had a flat battery and had to be jump started for a test drive, there were loads of fault codes when they were checked and it was a few days after I took the car away before the stop/start kicked in. If I were you I'd start looking at battery deals....
-
The car has done very little mileage over these last few years. Possibly if you were able to get out more often the battery may not have lost its effectiveness as easily these cars are meant to be driven
-
Oh cr*p :shocked:. I realised the other day that my stop/start hasn't worked once in the past 2 months. I have a van for work so the cars used mostly on the weekend for a few 20 min drives and has been since owning it.
Is there any way to check the battery level without owning an OBD11 or similar??
Will buy one asap I think, in case I need to program a new battery and check the charge etc
Edit// Also, can anyone confirm if I need an OBD11 Pro to setup a new battery or is a standard OBD11 ok??. Not sure if the long coding feature of the Pro is required or not
-
As far as I'm aware if you're replacing the battery you shouldn't need to do anything. I replaced mine with a Euro Car Parts AGM and it worked fine, no need for coding.
-
You have to code the car simply so that it knows it has to charge a different battery - type, charging rate, speed etc

Easy to do? Looks like my original battery might be on its way out :sad:

Before anyone goes and gets a new battery, go get a free battery health check at Halfords. It will give you a percentage reading of how healthy it is.

VW are charging £260 to supply and fit the battery here with coding. Seems to be the same price everywhere in the network. ECP are even more expensive £200 plus for the battery with discount. Cheapest option is Halfords but they are proving painful to deal with. Halfords brand batteries made by Yuasa. I’m going to try and get one fitted by them I’m the morning. Quantity varies wildly store to store
-
Lots of knackered batteries at the moment.... because nobody is using their cars...
-
I called a local specialist. £310. What a joke.
-
Seems quite a mark-up considering you can buy the correct Varta or Bosch AGM battery for around £130.
-
Just a lot of demand and missed profits to make up for I guess.... like pubs charging seven quid for a pint...

Super easy. There are plenty of tutorials out there. If no one has linked one by tonight, I'll put the steps up.
I bought an AGM096 battery from battery megastore for just under £130. The OBDEleven was about £40 from Amazon.

Here’s Golf Dave’s tutorial that I used. :cool:

That'll do! Saves me a job later

A genuine battery is alright if you're worried about concurs competitions, but personally I'd just get one with the best warranty. I Actually got a Lifetime Yuasa from Halfords and they replaced it without hesitation, makes it even better if you have a trade card :tongue:

A lifetime what? I thought you meant warranty but it says 5 years.
Still, 5 years is a great warranty for a battery when they're meant ot last 6-8 on average

For a period of time Yuasa offered a lifetime warranty battery and I just happened to need one for my mk5 so grabbed one, think it was £160 at the time full price or £140 trade card. :smiley:
They stopped offering them and now only sell up to 5 year warranty batteries.

Just a little update. My stop/start hasn't been working for a while but today it started kicking in, so maybe the battery level has improved now?
But I've noticed something else strange happening and it did it twice in a row. I reversed my car into my drive, put the handbrake on, and put it into neutral.... at which point the engine turned off and when it put it back into first it said on the screen 'Start engine manually'
What I thinks happening is that the stop/start enables once the cars put into neutral but won't start up due to the battery level? maybe?. Anyone else had this happen?
My OBDeleven arrived the other day so will check the battery charge. I should be able to figure out how to find it on the app myself but it anyone can point me in the exact direction then that would be great!
-
Had you opened a door, even if you didn't get out?
-

Nope. That wouldn't shut the engine off though?
-
My previous car definitely did a similar thing, pretty sure it was when it stopped the engine at my works gates and when I got back in from opening them it gave the same message. Probably worth a perusal through the instructions, must be in there somewhere.
-
Are your cars manual? Otherwise I might have said that it could be having to have your foot on the brake pedal before moving off/starting the engine.
-
Yeah it’s a manual. Just confused as it’s never done it before
-
Invest in a battery tester which will test the battery on load. I suspect your problems will be solved by getting a new one and coding it in for stop start. (or coding the stop/start out which is what I did)

Is it possible to code the car such that S/S is off by default, but can be turned on with the button? The opposite of the standard setup?
Or is it a case of you can only code it out completely?
-
Just plugged the OBDeleven in for the first time and it says the battery voltage is 11.5v. Ffs!
-
I don't know if it is just my car and the fact that my battery is on the way out, but when I plugged the OBD11 in, it eats battery life for fun.
So much so after about 30 mins or so of messing about the car would not start and I had to recharge the battery.
Unless I was coding something that needed the engine to be off I had to have the car running :sad:

I have the Pro Version and I coded it out completely with an APP within the software. It can also be done manually in the adaptations. Basically, you are fooling the car into thinking it doesnt meet the requirements for stop/start to be available.
AFAIK, (open to corection), you cannot code it so that it can be turned on with the button but defaulted to off.
-
Iirc, I read somewhere that there is a cable that goes to the battery that if disconnected will disable stop/start. Worth a search/google.
Personally I like it on and only rarely switch it off. Also the fact that it is effectively a warning for a low battery.

You are correct Watts thats the battery monitoring module. Each to their own, i cant stand STOP/START. the poor battery and starter motor!!

My stop start is not working on a 22 month old car just bought. Mileage suggests lengthy time unused. Dealer said it would work after the battery had a good charge. Not happened. Voltage is 12 .2v. Is this low enough to stop it working? Since battery warranty is 2 years wondered if dealer would replace it? Thoughts welcome.

Dealer replaced my battery just under 3 years old when my start stop was intermittent. Works fine now.
-
Update - battery changed and coded. Has made zero difference. No error codes but no stop/start.
-
Do you get the message about stop start pop up on the MIB?
And the A with a line through it?
If you do get it on the Mib, press the "i" button and you can see why its not stopping... might need to be on the vehicle status screen to see it.

Aren't batteries like this designed to run with stop/start? I imagine the starter motor too? So surely it won't do any harm as that's what they're made to do and they're not the same as on a standard car without it

Thanks! That's actually a good read and clears a few things up. Personally I like the stop/start and impressed by how flawlessly it works ....just a shame that mines still stopped working for some reason :grin::grin: ffs

If you believe that stop/start does no harm to starting motor and battery fair play to you. There’s a reason my battery lasted almost 8 years on my GTi and most here are having trouble with theirs after 2/3. Each to their own tho. I can’t stand stop start. Have it permanently disabled on the wife’s E class wagon also

And this is precisely why I turn off stop start on every trip. Every car battery I've owned has lasted ~8 years - longer in my last GTI (mk5). With the new stop start systems it seems 3 year, often less is the standard. For me the economics of stop start do not stack up, as these S/S batteries are freaking expensive. All for a thimble of petrol saved per week.

I've said it before and I'll say it again.... its not about a X amount of fuel cost savings for you, its about a small percentage (its about 5%) decrease in carbon dioxide emissions across Europe. In 2015 the average car across the EU emitted 1.2 tonnes of CO2 per year and there are roughly 260 million of them.
5% of 1.2 tonnes times 260 million equals 15.6 million tonnes of Co2 per year.
And thats probably a conservative estimate.
Until someone waves a magic wand and fixes the overall problem, all we can do is to try to slow it here, slow it there and 15.6 million tonnes is a good chunk just by giving you a little annoyance.
-
Probably the reason so many on here have batteries going so quickly is because of VW fitting second rate EFB batteries instead of AGM. Low use during the pandemic won't have helped either. Having said that, my mum's Mini has stop/start and is almost 7 years old but is still on its original battery.

You do know ye are not in the EU anymore right?! :whistle:
-
Don't be daft.... I am using those figures to show you what that annoying start stop does on a macro scale because the numbers for vehicles and emmissions are available as a dataset for "EU". I could have used USA or China or some other large dataset, but its easier to think of something more akin to your own life.
