- here we show you how to change fit and programme Stop Start AGM Battery on most modern cars
NEVER put negative on first, ALWAYS positive first, any time, all the tme, every time, POSITIVE FIRST.
Once you've loosen the negative terminal disconnect it right away before loosening and removing the positive. If the tool touches any metal part of the engine when undoing the positive while the negative is still connected it will make spark, might damge something.
Removal: disconnect negative first
Installation: connect positive first
I did this successfully on a 2013 Golf TSI 1400cc. Used the Ancel VD700 (approx. £110) to program battery code. I noticed your "original" battery code showed JCB, although battery was NOT JCB. Mine was the same! All works fine - as long as car "knows" new battery (and type) is fitted - so it doesn't damage it by under, or over, charging it!
Also noticed if you monitor battery voltage while driving, it is completely different charging pattern to older conventional cars!
Youre a lifesaver. I'm replacing the battery of my 2015 VW polo from an EFB to an AGM battery myself as its really pricey at the mechanic and would have had no idea what affordable OBD scanner to order if not for you saying you used an Ancel VD700. Luckily the new AGM battery has the same capacity so I dont need a more expensive OBD scanner like the OBDeleven PRO to program it. The Ancel VD700 would suffice as I just need to register it as a new battery :) Now Im just waiting for both my new battery and scanner to be delivered!
@@Icolorimutevoli glad I could help! The Ancel device has menu enabling you to change battery type and ALSO battery capacity - so if new battery was a bit bigger you can just input whatever the new battery capacity might be!
From what I have read, type "Binary - AGM" are for the spiral-wound AGM (like Optima). All other AGM batteries should be type "Fleece".
This is true. OEM battery type for AGM is Fleece.
Thank you, I have an EFB battery on my 2020 Rav4 and has been replaced twice the battery. Some are saying the vehicle DCM is causing the battery to die others are saying the OEM battery from toyota are bad and recommending I switch to AGM.
GOOD NEWS....I did battery swap...on start up bunch error symbols......drove off......they went off ...NO COMPUTER
Did the same on my A3 2017 and it works normally for weeks now already
The problem isn't that it won't work and the lights won't go off... The problem is that the computer treats your new battery as if it were the old battery, unless you adapt the car to the new battery. This means that the charging cycles will act like an old battery, and your new battery will likely not last nearly as long as it could/should.
Mine doesn’t start it says button for system assistance defective. What should I do?
Will you recommend to buy the Autel maxicom mk808bt, the new version of yours?
Do the older version b6 passat use Stop start. I have an AGM battery in a 2009 b6 but it only was a wire on negative terminal unlike yours which had wires on both terminals
Fitting would be exactly the same procedure
AGM batteries should be set to Fleece. This is the factory setting
Correct, allot of people get mistaken just because it has the letters AGM, binary AGM refers to spiral AGM batteries, the AGM fitted here is a flat plate with Fleece
Sorry for all the questions. Did the start stop system stop working with your weak battery? BTW I’m from Ireland too, Longford.
No it would work but you could hear it struggle so changed it before it left me stranded
Mine disabled win battery got low notice it struggle Replaced battery now it’s not working idk if it’s because I replaced it with a AGM Battery from Walmart or it need to be programmed what y’all think
Binary-AGM or Fleece in the technology section? Some say one some say the other. But which is correct?
Fleece. It's the factory setting for AGM batteries
Binary AGM is spiral ,not flat plate FLEECE
Hi changed my battery on 2011 touran but didn’t program it there is no light on the dash , is it going to be ok or not , I smell something burning since I changed the battery, do you think it could be the change of the new battery?
It should need programming in or it would overcharge the new battery reducing its life drastically
Nobody’s going to mention the + terminal cable he ripped off taking out the sleeve? 2:20
Halfords have their own coding machine does it do the job ?
Having a nightmare trying to code a brand new bosch S5A to my caddy just becuase it didnt come with a BEM code, have you any ideas what to do?
As long as the amps are set correctly you can usually just change 1 digit from your old BEM code and it should be fine.
AGM is "Fleece" for VW. Your battery didnt look like "Binary AGM".
How can you tell which cars need battery programming..is it all start stop and cars with sensor on the negative?
Yes. Most modern cars with AGM batteries need to register it to avoid overcharge and reducing the life considerably.
If not sure once we plug our scan tool in it would have the option to register the new battery if it requires it
@@ORileysAutos thanks for the information
Did you put a battery tester on it before you replaced it? If so how many EN amps were left?
Only 65cca!! Not sure how it was even starting
any cheaper reader/scanners that would do that thank you
I'm sure there are plenty but not sure what models.
Query it with Launchtech.co.uk
Why does the heat (car) says 90 degrees after installing battery ? How to set this to zero when starting
The car was being used before the battery installation. It's still on 90 as it was only off for 10 minutes while installing the new battery so it's not enough time to cool down 👍🏻
Ok thanks,it's because i changed my battery and now the degrees say 90 when starting..didn't that before
@@ellendil280 did you plug in a diagnostic scanner?
No i did not,but it fixt itself after a second ride 😉
Will the radio need re-coding aswell?
No
thankz alot
How old was battery?
5 years
@@ORileysAutos They don’t seem to last long. My Passat will be 4 in February and it doesn’t have the same kick, especially in mornings or when ambient temps are low. It read 43% SOH on a conductance tester. Exact same battery but mine located in the boot.
My fathers 2007 Passat still on original battery lol
Mobile mechanic myself. Why people bother to post videos on how to do their own business jobs when it basically countrywide and a massive effect on downturn of new customers.
All you should have done is measure on min setting battery as cranking. Less 9v change battery. Or disconnected battery and connected AUTEL battery tester and analysed it.
Stay busy
